# Guide for authenticated requests
|
||||
|
||||
The OpenAIRE APIs can be accessed over HTTPS both by authenticated and non authenticated requests.
|
||||
You can use authenticated requests to increase the rate limit of your requests (please refer [here](./terms#authentication--limits) for the current API rate limits).
|
||||
There are 2 main modes that you can use to authenticate API requests:
|
||||
|
||||
* [Personal access tokens](#personal-access-token)
|
||||
* [Registered services](#registered-services)
|
||||
|
||||
|
||||
In the following, we elaborate on these modes.
|
||||
|
||||
## Personal access token
|
||||
|
||||
To access the OpenAIRE APIs with better rate limits you can use your personal access token. To have access to the following functionalities you need to login to OpenAIRE. In case you are not already a member you will need to register first and provide your [Personal information](https://develop.openaire.eu/personal-info).
|
||||
|
||||
:::info New!
|
||||
The registration process has been updated! In order to visit the Personal Token and Registered Services functionalities you need to fill in the Personal Information form available [here](https://develop.openaire.eu/personal-info). This update will not affect the operation of your existing services. However, if you want to register a new service or access/modify an existing one, you will need to provide your personal information first.
|
||||
:::
|
||||
|
||||
### How to create your personal access token
|
||||
|
||||
To create your personal access token go to [your personal access token page](https://develop.openaire.eu/personal-token) and copy it!
|
||||
|
||||
:::info
|
||||
Your access token is valid for an hour.
|
||||
:::
|
||||
|
||||
:::caution
|
||||
Do not share your personal access token. Send your personal access token over HTTPS.
|
||||
:::
|
||||
|
||||
### How to use your personal access token
|
||||
|
||||
To access the OpenAIRE APIs send your personal access token using the Authorization header.
|
||||
```js
|
||||
GET https://api.openaire.eu/{resourceServicePath}
|
||||
Authorization: Bearer {ACCESS_TOKEN}
|
||||
```
|
||||
|
||||
### An hour is not enough? What to do.
|
||||
|
||||
To prolong your access to our APIs you can use a **refresh token** that allows you to programmatically issue a new access token.
|
||||
|
||||
To get your refresh tokeng go to [your personal access token page](https://develop.openaire.eu/personal-token) and click the **"Get a refresh token"** button to get your refresh token.
|
||||
|
||||
OpenAIRE refresh token expires after 1 month.
|
||||
|
||||
In case you already have a refresh token a new one will be issued and the old one will no longer be valid.
|
||||
|
||||
Please copy your refresh token and store it confidentially. You will not be able to retrieve it. Do not share your refresh token. Send your refresh token over HTTPS.
|
||||
|
||||
Since the OpenAIRE refresh token expires after one month, when a client gets a refresh token, this token must be stored securely to keep it from being used by potential attackers. If a refresh token is leaked, it may be used to obtain new access tokens and access protected resources until a new one is issued or it expires.
|
||||
|
||||
To get a personal access token using your refresh token you need to make the following request:
|
||||
```js
|
||||
GET https://services.openaire.eu/uoa-user-management/api/users/getAccessToken?refreshToken={your_refresh_token}
|
||||
```
|
||||
|
||||
The response has the following format:
|
||||
```json
|
||||
{
|
||||
"access_token": "...",
|
||||
"token_type": "Bearer",
|
||||
"refresh_token": "...",
|
||||
"expires_in": "...",
|
||||
"scope": "...",
|
||||
"id_token": "..."
|
||||
}
|
||||
```
|
||||
|
||||
## Registered services
|
||||
|
||||
If you have a service (client) that you want to interact with the OpenAIRE APIs you need to register it.
|
||||
|
||||
:::info
|
||||
You can register up to 5 services.
|
||||
:::
|
||||
|
||||
We offer two ways of authenticting your service: the Basic Authentication and the Advanced Authentication.
|
||||
|
||||
### Which one is for me?
|
||||
|
||||
| | How | Client Credential Issuer | Authentication Method |
|
||||
| --- | --- | --- | --- |
|
||||
| **Basic** | Client ID & Client Secret | OpenAIRE AAI server | Client Secret (Basic) |
|
||||
| **Advanced** | Private Key signed JWT | Service owner | Private Key JWT Client Authentication |
|
||||
|
||||
For the **Basic Authentication** method the OpenAIRE AAI server generates a pair of _Client ID_ and _Client Secret_ credentials for your service upon its registration. The service sends the client id and client secret when authenticating to the OpenAIRE AAI Server to obtain the access token for the OpenAIRE APIs. The OpenAIRE AAI server checks whether the client id and client secret sent is valid. [Continue reading for the Basic Authentication](#basic-service-authentication-and-registration).
|
||||
|
||||
For the **Advanced Authentication** method your service does not send a client secret but it uses a _self signed client assertion_ to authenticate to the OpenAIRE AAI server in order to obtain the access token for the OpenAIRE APIs. The client assertion is a JWT that must be signed with RSASSA using SHA-256 hash algorithm. The OpenAIRE AAI server validates the client assertion using the public key that you have provided upon the service registration. [Continue reading for the Advanced Authentication](#advanced-service-authentication-and-registration).
|
||||
|
||||
:::info
|
||||
The Advanced Authentication method allows the OpenAIRE AAI server to verify that the client authentication request at the token endpoint was signed by your service and not altered in any way. This is more computation intensive compared to the Basic Authentication but it ensures non-repudiation. On the other hand, the Basic Authentication is more lightweight and easy to deploy but it does not provide signature verification, and there is always a possibility of the Client ID/secret credentials being stolen. Note that tThe Advanced authentication method gives a higher level of security to the process as long as it is used correctly, i.e. when the signed JWT has a short duration. When the duration of the JWT is long, the process is no different from the basic one.
|
||||
:::
|
||||
|
||||
### Basic service authentication and registration
|
||||
|
||||
To have access to the following functionalities you need to login to OpenAIRE. In case you are not already a member you will need to register first and provide your [Personal information](https://develop.openaire.eu/personal-info).
|
||||
|
||||
:::info New!

|
||||
|
||||
#### How to register your service
|
||||
|
||||
To register your service you need to:
|
||||
|
||||
1. Go to your [Registered Services](https://develop.openaire.eu/apis) page and click the **\+ New Service** button.
|
||||
2. Provide the mandatory information for your service.
|
||||
3. Select the **Basic** Security level.
|
||||
4. Click the **Create** button.
|
||||
|
||||
Once your service is created, the _Client ID_ and _Client Secret_ will appear on your screen. Click "OK" and your new service will be appear in the list of your [Registered Services](https://develop.openaire.eu/apis) page.
|
||||
|
||||
#### How to make a request
|
||||
|
||||
##### Step 1. Request for an access token
|
||||
|
||||
To make an access token request use the _Client ID_ and _Client Secret_ of your service.
|
||||
```js
|
||||
curl -u {CLIENT_ID}:{CLIENT_SECRET} \
|
||||
-X POST 'https://aai.openaire.eu/oidc/token' \
|
||||
-d 'grant_type=client_credentials'
|
||||
```
|
||||
|
||||
where **{CLIENT_ID}** and **{CLIENT_SECRET}** are the _Client ID_ and _Client Secret_ assigned to your service upon registration.
|
||||
|
||||
The response is:
|
||||
```json
|
||||
{
|
||||
"access_token": ...,
|
||||
"token_type": "Bearer",
|
||||
"expires_in": ...
|
||||
}
|
||||
```
|
||||
|
||||
Store the access token confidentially on the service side.
|
||||
|
||||
##### Step 2. Make a request
|
||||
|
||||
To access the OpenAIRE APIs send the access token returned in **Step 1**.
|
||||
```js
|
||||
GET https://api.openaire.eu/{resourceServicePath}
|
||||
Authorization: Bearer {ACCESS_TOKEN}
|
||||
```
|
||||
|
||||
### Advanced service authentication and registration
|
||||
|
||||
|
||||
To have access to the following functionalities you need to login to OpenAIRE. In case you are not already a member you will need to register first and provide your [Personal information](https://develop.openaire.eu/personal-info).
|
||||
|
||||
:::info New!
|
||||
The registration process has been updated! In order to visit the Personal Token and Registered Services functionalities you need to fill in the Personal Information form available [here](https://develop.openaire.eu/personal-info). This update will not affect the operation of your existing services. However, if you want to register a new service or access/modify an existing one, you will need to provide your personal information first.
|
||||
:::
|
||||
|
||||
For the **Advanced Authentication** method your service does not send a client secret but it uses a _self signed client assertion_ to obtain the access token for the OpenAIRE APIs. The client assertion is a JWT that must be signed with RSASSA using SHA-256 hash algorithm. The OpenAIRE AAI server validates the client assertion using the public key that you have provided upon the service registration.
|
||||
|
||||
#### Prepare to register your service
|
||||
|
||||
Before you register your service you need to prepare a pair of a private key and a public key on your side.
|
||||
|
||||
:::info
|
||||
We accept keys signed with RSASSA using SHA-256 hash algorithm.
|
||||
:::
|
||||
|
||||
To create the key pair you have the following options:
|
||||
|
||||
* Use OpenAIRE authorization server built in tool. You can access the service here: [https://aai.openaire.eu/oidc/generate-oidc-keystore](https://aai.openaire.eu/oidc/generate-oidc-keystore).
|
||||
The response is your **Public and Private Keypair** and has the following format:
|
||||
```json
|
||||
{
|
||||
"p" : ...,
|
||||
"kty" : "RSA",
|
||||
"q" : ...,
|
||||
"d" : ...,
|
||||
"e" : "AQAB",
|
||||
"kid" : ...,
|
||||
"qi" : ...,
|
||||
"dp" : ...,
|
||||
"alg" : "RS256",
|
||||
"dq" : ...,
|
||||
"n" : ....
|
||||
}
|
||||
```
|
||||
|
||||
Use the public key parameters (kty, e, kid, alg, n) to create your **Public Key** in the following format:
|
||||
```json
|
||||
{
|
||||
"kty": "RSA",
|
||||
"e": "AQAB",
|
||||
"kid": ...,
|
||||
"alg": "RS256",
|
||||
"n": ...
|
||||
}
|
||||
```
|
||||
|
||||
:::info
|
||||
Store both the **Public and Private keypair** and the **Public key**. You will need them to register your service.
|
||||
:::
|
||||
|
||||
:::caution
|
||||
Store the **Public and Private keypair** confidentially on the service side.
|
||||
:::
|
||||
|
||||
* Use openssl and then convert the keys to jwk format using PEM to JWK scripts, such as [https://github.com/danedmunds/pem-to-jwk](https://github.com/danedmunds/pem-to-jwk). Alternatively, the client application can read the key pair in PEM format and then convert them, using JWK libraries. Use the public key parameters (kty, e, kid, alg, n) to the service registration.
|
||||
|
||||
:::info
|
||||
You can also provide a public key in JWK format that can be accessed using a link.
|
||||
:::
|
||||
|
||||
#### How to register your service
|
||||
|
||||
To register your service you need to:
|
||||
|
||||
1. Go to your [Registered Services](https://develop.openaire.eu/apis) page and click the **\+ New Service** button.
|
||||
2. Provide the mandatory information for your service.
|
||||
3. Select the **Advanced** Security level.
|
||||
4. Use the public key parameters (kty, e, kid, alg, n) you previously produced to declare your **"Public Key"** **"By value"** in the following format:
|
||||
```json
|
||||
{
|
||||
"kty": "RSA",
|
||||
"e": "AQAB",
|
||||
"kid": ...,
|
||||
"alg": "RS256",
|
||||
"n": ...
|
||||
}
|
||||
```
|
||||
**\- OR -**
|
||||
|
||||
If your service has a public key in JWK format that can be accessed using a link, you can set **“Public Key”** to **“By URL”**.
|
||||
|
||||
5. Click the **Create** button.
|
||||
|
||||
Once your service is created it will appear in the list of your [Registered Services](https://develop.openaire.eu/apis) page, with the **Service Id** that was automatically assigned to it by the AAI OpenAIRE service.
|
||||
|
||||
#### How to make a request
|
||||
|
||||
##### Step 1. Create and sign a JWT
|
||||
|
||||
Your service must create and sign a JWT and include it in the request to token endpoint as described in the [OpenID Connect Core 1.0, 9. Client Authentication](https://openid.net/specs/openid-connect-core-1_0.html#ClientAuthentication).
|
||||
|
||||
To create a JWT you can use [https://mkjose.org/](https://mkjose.org/). To do so you need to create a **payload** that should contain the following claims:
|
||||
|
||||
```json
|
||||
{
|
||||
"iss": "{SERVICE_ID}",
|
||||
"sub": "{SERVICE_ID}",
|
||||
"aud": "https://aai.openaire.eu/oidc/token",
|
||||
"jti": "{RANDOM_STRING}",
|
||||
"exp": {EXPIRATION_TIME_OF_SIGNED_JWT}
|
||||
}
|
||||
```
|
||||
|
||||
* **iss**, _(required)_ the “issuer” claim identifies the principal that issued the JWT. The value is the **Service Id** that was created when you registered your service.
|
||||
* **sub**, _(required)_ the “subject” claim identifies the principal that is the subject of the JWT. The value is the **Service Id** that was created when you registered your service.
|
||||
* aud, _(required)_ the “audience” claim identifies the recipients that the JWT is intended for. The value is **https://aai.openaire.eu/oidc/token**>.
|
||||
* **jti**, _(required)_ The “JWT ID” claim provides a unique identifier for the JWT. The value is a random string.
|
||||
* **exp**, _(required)_ the “expiration time” claim identifies the expiration time on or after which the JWT **MUST NOT** be accepted for processing. The value is a timestamp in **epoch format**.
|
||||
|
||||
Fill in the payload in the form available at [https://mkjose.org/](https://mkjose.org/), select the Signing Algorithm to be **RS256 using SHA-256** and paste the **Public and Private Keypair** previously created.
|
||||
|
||||
To check your JWT you can go to [https://jwt.io/](https://jwt.io/). The **header** should contain the following claims:
|
||||
```json
|
||||
{
|
||||
"alg": "RS256",
|
||||
"kid": ...
|
||||
}
|
||||
```
|
||||
|
||||
where **kid** is the one of your **Public and Private Keypair** you used to sign the JWT in **Step 1**.
|
||||
|
||||
:::caution
|
||||
Store the signed key confidentially on the service side. You will need it in Step 2.
|
||||
:::
|
||||
|
||||
##### Step 2. Request for an access token
|
||||
|
||||
To make an access token request use the _signed JWT_ that you created in **Step 1**. The OpenAIRE AAI server will check if the signed JWT is valid using the public key that you declared in the **"How to register your service"** process.
|
||||
```js
|
||||
curl -k -X POST "https://aai.openaire.eu/oidc/token" \
|
||||
-d "grant_type=client_credentials" \
|
||||
-d "client_assertion_type=urn:ietf:params:oauth:client-assertion-type:jwt-bearer" \
|
||||
-d "client_assertion={signedJWT}"
|
||||
```
|
||||
where **{signedJWT}** is the signed JWT created in **Step 1**.
|
||||
|
||||
The response is:
|
||||
```json
|
||||
{
|
||||
"access_token": {ACCESS_TOKEN}
|
||||
"token_type":"Bearer",
|
||||
"expires_in": ...,
|
||||
"scope":"openid"
|
||||
}
|
||||
```
|
||||
|
||||
Store the access token confidentially on the service side.
|
||||
|
||||
##### Step 3. Make a request
|
||||
|
||||
To access the OpenAIRE APIs send the access token returned in **Step 2**.
|
||||
```js
|
||||
GET https://test.openaire.eu/{resourceServicePath}
|
||||
Authorization: Bearer {ACCESS_TOKEN}
|

# Broker API
|
||||
|
||||
|
||||
## Introduction
|
||||
|
||||
The Broker Service is available to use via the OpenAIRE Content Provider Dashboard. Thanks to the Broker, repositories, publishers or aggregators can exchange metadata and enrich their local metadata collection by subscribing to notifications of different types. The Broker is able to notify providers when the OpenAIRE Graph contains information that is not available in the original collection of the data source. In particular, the data source manager can subscribe via the [Content Provider Dashboard](https://provide.openaire.eu) and be notified about:
|
||||
|
||||
* Additional PIDs of its publications (e.g. DOIs)
|
||||
* Links to projects
|
||||
* ORCID that can be associated to an author of datasource publications
|
||||
* Links to Open Access versions
|
||||
* Additional classification subjects (e.g. subjects from standard schemes like ACM, JEL and DDC)
|
||||
* Abstracts identified in duplicate publications
|
||||
* Missing publication dates
|
||||
|
||||
All Repository managers approaching the Content Provider Dashboard will be offered the possibility to preview a set of enrichments relative to their repository that OpenAIRE can derive from the Graph. More specifically, enrichments will be organized into categories named topics and representing the different types of enrichments OpenAIRE can build. For each topic the preview consists of 100 “enrichment events”, a subset of all the possible enrichments pertinent to a given repository in the OpenAIRE Graph, that the user can explore by applying filters on different criteria and the total number of events that can be potentially built is highlighted in the UI. Repository managers can create subscriptions for specific topics and that include the filtering criteria they used to analyze the enrichments preview, or can subscribe to all the available topics with no restrictions at once. Once the repository manager creates a subscription, the algorithm analyzing the OpenAIRE Graph will produce the full set of enrichments for the manager's repository, possibly far beyond the 100 enrichments available in the preview. The enrichments will be made available as notifications in a dedicated section in the Content Provider Dashboard UI to be further checked as well as through the broker service API for programmatic access. Notifications will be sent to subscribers every time the OpenAIRE Graph will be updated and analyzed to derive the enrichments.
|
||||
|
||||
## Usage Example
|
||||
|
||||
The following commands indicate how the broker API documented at [api.openaire.eu/broker](https://api.openaire.eu/broker/swagger-ui/index.html) can be used to access the set of enrichments:
|
||||
|
||||
1. Get the list of subscriptions for a given subscriber, e.g.
|
||||
|
||||
```js
|
||||
curl -X GET --header 'Accept: application/json' 'https://api.openaire.eu/broker/subscriptions?email=[subscriber_email]'
|
||||
```
|
||||
|
||||
2. Extract the subscription ID and use it to access the 1st page of enrichment notification records
|
||||
|
||||
```js

# Getting a single entity
|
||||
|
||||
This is a guide on how to retrieve detailed information on a single entity using the OpenAIRE Graph API.
|
||||
|
||||
## Endpoints
|
||||
Currently, the Graph API supports the following entity types:
|
||||
|
||||
- Research products - endpoint: `GET /researchProducts/{id}`
|
||||
- Organizations - endpoint: `GET /organizations/{id}`
|
||||
- Data sources - endpoint: `GET /dataSources/{id}`
|
||||
- Projects - endpoint: `GET /projects/{id}`
|
||||
|
||||
You can retrieve the data of a single entity by providing the entity's OpenAIRE identifier (id) in the corresponding endpoint.
|
||||
The OpenAIRE id is the primary key of an entity in the OpenAIRE Graph.
|
||||
|
||||
:::note
|
||||
Note that if you want to retrieve multiple entities based on their OpenAIRE ids, you can use the [search endpoints and filter](./searching-entities/filtering-search-results.md#or-operator) by the `id` field using `OR`.
|
||||
:::
|
||||
|
||||
## Response
|
||||
The response of the Graph API is a [Research product](../../data-model/entities/research-product.md), [Organization](../../data-model/entities/organization.md), [Data Source](../../data-model/entities/data-source.md), or [Project](../../data-model/entities/project.md), depending on the endpoint used.
|
||||
|
||||
## Example
|
||||
|
||||
In order to retrieve the research product with OpenAIRE id: `doi_dedup___::2b3cb7130c506d1c3a05e9160b2c4108`,
|
||||
you have to perform the following API call:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts/doi_dedup___::a55b42c0d32a4a24cf99e621623d110e](https://api-beta.openaire.eu/graph/researchProducts/doi_dedup___::a55b42c0d32a4a24cf99e621623d110e)
|
||||
|
||||
This will return all the data of the research product with the provided identifier:
|
||||
|
||||
```json
|

# Graph API <span class="theme-doc-version-badge badge badge--secondary">beta</span>
|
||||
|
||||
|
||||
The OpenAIRE Graph API provides a comprehensive way for developers to explore the [OpenAIRE Graph](https://graph.openaire.eu/), a vast interconnected dataset that aggregates metadata from a wide range of scholarly resources.
|
||||
The Graph API offers endpoints for accessing and querying this interconnected dataset, enabling users to retrieve detailed information on research products, data sources, organizations, and projects.
|
||||
|
||||
## Base URL and Swagger documentation
|
||||
|
||||
The base URL of the Graph API is:
|
||||
```
|
||||
https://api-beta.openaire.eu/graph/
|
||||
```
|
||||
|
||||
You can access the API Swagger documentation in [https://api-beta.openaire.eu/graph/swagger-ui/index.html#/](https://api-beta.openaire.eu/graph/swagger-ui/index.html#/).
|
||||
|
||||
## Notes
|
||||
Please note that the Graph API:
|
||||
|
||||
- is intended for data discovery and exploration, hence you are now allowed to navigate the full result set: you are limited to the first 10,000 results of a search query. If you are interested to access the whole graph, we encourage you to download the [OpenAIRE full Graph dataset](../../downloads/full-graph.md).
|
||||
|
||||
- adhers to the [terms of use](../terms.md) of the OpenAIRE public APIs - certain (rate limit) restrictions apply.

# Making requests
|
||||
|
||||
This guide provides examples of how to make requests to the OpenAIRE Graph API using different programming languages.
|
||||
|
||||
## Using `curl`
|
||||
|
||||
```bash
|
||||
curl -X GET "https://api-beta.openaire.eu/graph/researchProducts?search=OpenAIRE%20Graph&type=publication&page=1&pageSize=10&sortBy=relevance%20DESC" -H "accept: application/json"
|
||||
```
|
||||
|
||||
|
||||
## Using Python (with `requests` library)
|
||||
|
||||
```python
|
||||
import requests
|
||||
|
||||
url = "https://api-beta.openaire.eu/graph/researchProducts"
|
||||
params = {
|
||||
"search": "OpenAIRE Graph",
|
||||
"type": "publication",
|
||||
"page": 1,
|
||||
"pageSize": 10,
|
||||
"sortBy": "relevance DESC"
|
||||
}
|
||||
headers = {
|
||||
"accept": "application/json"
|
||||
}
|
||||
|
||||
response = requests.get(url, headers=headers, params=params)
|
||||
|
||||
if response.status_code == 200:
|
||||
data = response.json()
|
||||
print(data)
|
||||
else:
|
||||
print(f"Failed to retrieve data: {response.status_code}")
|
||||
|
||||
```
|
||||
|
||||
:::note
|
||||
Note that when using `curl` you should ensure that the URL is properly encoded, especially when using special characters or spaces in the query parameters. On the contrary, the `requests` library in Python takes care of URL encoding automatically.

# Filtering search results
|
||||
|
||||
Filters can be used to narrow down the search results based on specific criteria.
|
||||
Filters are provided as query parameters in the request URL (see [here](./searching-entities.md) for the available search entpoints).
|
||||
|
||||
Multiple filters can be provided in a single request; they should be formatted as follows:
|
||||
`param1=value1¶m2=value2&...¶mN=valueN`.
|
||||
|
||||
:::note
|
||||
Filters are combined using the logical `AND` operator.
|
||||
If a filter is provided multiple times, its values are combined using the logical `OR` operator.
|
||||
For more information on how to use logical operators when searching and filtering, see [Using logical operators](#using-logical-operators).
|
||||
:::
|
||||
|
||||
Examples:
|
||||
|
||||
- Get all research products that contain the word `"covid"`, sorted by popularity in descending order:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search=covid&sortBy=popularity DESC](https://api-beta.openaire.eu/graph/researchProducts?search=covid&sortBy=popularity%20DESC)

|
||||
|
||||
|
||||
## Using logical operators
|
||||
|
||||
The API supports the use of logical operators `AND`, `OR`, and `NOT` to refine your search queries.
|
||||
These operators help you combine or exclude one or more values for a specific filter.
|
||||
|
||||
|
||||
### `AND` operator
|
||||
|
||||
Use the `AND` operator to retrieve results that include all specified values. This narrows your search.
|
||||
|
||||
Examples:
|
||||
|
||||
- Get research products that contain both `"climate"` and `"change"`:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search=climate AND change](https://api-beta.openaire.eu/graph/researchProducts?search=climate%20AND%20change)
|
||||
|
||||
- Get research products that are classified with both Fields of Study (FOS) `"03 medical and health sciences"` and `"0502 economics and business"`:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?fos="03 medical and health sciences" AND "0502 economics and business"](https://api-beta.openaire.eu/graph/researchProducts?fos=%2203%20medical%20and%20health%20sciences%22%20AND%20%220502%20economics%20and%20business%22)
|
||||
|
||||
:::note
|
||||
Note that when multiple tokens denote a single filter value, you should enclose them in double quotes, as in the FOS example above.
|
||||
:::
|
||||
### `OR` operator
|
||||
|
||||
Use the `OR` operator to retrieve results that include any of the specified terms. This broadens your search.
|
||||
The same functionality can be achieved by providing multiple times the same query parameter or using a comma to separate the values.
|
||||
|
||||
Examples:
|
||||
|
||||
- Get research products with the OpenAIRE ids `doi_dedup___::2b3cb7130c506d1c3a05e9160b2c4108` or `pmid_dedup__::1591ebf0e0698ed4a99455ff2ba4adc0`:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?id=r3730f562f9e::539da48b3796663b17e6166bb966e5b1 OR pmid_dedup__::1591ebf0e0698ed4a99455ff2ba4adc0](https://api-beta.openaire.eu/graph/researchProducts?id=r3730f562f9e::539da48b3796663b17e6166bb966e5b1%20OR%20pmid_dedup__::1591ebf0e0698ed4a99455ff2ba4adc0)
|
||||
|
||||
- Get projects that are connected to organizations in the US or Greece:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US OR GR](https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US%20OR%20GR)
|
||||
|
||||
or by using the same query parameter multiple times: [https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US&relOrganizationCountryCode=GR](https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US&relOrganizationCountryCode=GR)
|
||||
|
||||
or just using comma: [https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US,GR](https://api-beta.openaire.eu/graph/projects?relOrganizationCountryCode=US,GR)
|
||||
|
||||
### `NOT` operator
|
||||
|
||||
Use the `NOT` operator to exclude specific terms from your search results. This refines your search by filtering out unwanted results.
|
||||
|
||||
Examples:
|
||||
|
||||
- Get research products that contain `"semantic"` but not `"web"`:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search=semantic NOT web](https://api-beta.openaire.eu/graph/researchProducts?search=semantic%20NOT%20web)
|
||||
|
||||
- Get all data sources that are not journals:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/dataSources?dataSourceTypeName=NOT Journal](https://api-beta.openaire.eu/graph/dataSources?dataSourceTypeName=NOT%20Journal)
|
||||
|
||||
|
||||
:::note
|
||||
All the above operators can be combined, along with parentheses, and quotes to create more complex queries.
|
||||
For example, to get research products that contain the phrase "semantic web" but not "ontology" or "linked data":
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search="semantic web" AND NOT (ontology OR "linked data")](https://api-beta.openaire.eu/graph/researchProducts?search=%22semantic%20web%22%20AND%20NOT%20(ontology%20OR%20%22linked%20data%22))

# Searching entities
|
||||
|
||||
This is a guide on how to search for specific entities using the OpenAIRE Graph API.
|
||||
|
||||
## Endpoints
|
||||
|
||||
Currently, the Graph API supports the following entity types:
|
||||
* Research products - endpoint: [`GET /researchProducts`](https://api-beta.openaire.eu/graph/researchProducts)
|
||||
* Organizations - endpoint: [`GET /organizations`](https://api-beta.openaire.eu/graph/organizations)
|
||||
* Data sources - endpoint: [`GET /dataSources`](https://api-beta.openaire.eu/graph/dataSources)
|
||||
* Projects - endpoint: [`GET /projects`](https://api-beta.openaire.eu/graph/projects)
|
||||
|
||||
Each of these endpoints can be used to list all entities of the corresponding type.
|
||||
Listing such entities can be more useful when using the [filtering](./filtering-search-results.md),
|
||||
[sorting](./sorting-and-paging.md#sorting), and [paging](./sorting-and-paging.md#paging) capabilities of the Graph API.
|
||||
|
||||
## Response
|
||||
|
||||
The response of the aforementioned endpoints is an object of the following type:
|
||||
|
||||
```json
|
||||
{
|
||||
header: {
|
||||
numFound: 36818386,
|
||||
maxScore: 1,
|
||||
queryTime: 21,
|
||||
page: 1,
|
||||
pageSize: 10
|
||||
},
|
||||
results: [
|
||||
...
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
It contains a `header` object with the following fields:
|
||||
- `numFound`: the total number of entities found
|
||||
- `maxScore`: the maximum relevance score of the search results
|
||||
- `queryTime`: the time in milliseconds that the search took
|
||||
- `page`: the current page of the search results (when using basic pagination)
|
||||
- `pageSize`: the number of entities per page
|
||||
- `nextCursor`: the next page cursor (when using cursor-based pagination, see: [paging](./sorting-and-paging.md#paging)
|
||||
|
||||
Finally, the `results` field contains an array of entities of the corresponding type (i.e., [Research product](../../../data-model/entities/research-product.md), [Organization](../../../data-model/entities/organization.md), [Data Source](../../../data-model/entities/data-source.md), or [Project](../../../data-model/entities/project.md)).

# Sorting and paging
|
||||
|
||||
The OpenAIRE Graph API allows you to sort and page through the results of your search queries.
|
||||
This enables you to retrieve the most relevant results and manage large result sets more effectively.
|
||||
|
||||
## Sorting
|
||||
Sorting based on specific fields, helps to retrieve data in the preferred order.
|
||||
Sorting is achieved using the `sortBy` parameter, which specifies the field and the direction (ascending or descending) for sorting.
|
||||
|
||||
* `sortBy`: Defines the field and the sort direction. The format should be `fieldname sortDirection`, where the `sortDirection` can be either `ASC` for ascending order or `DESC` for descending order.
|
||||
|
||||
The field names that can be used for sorting are specific to each entity type and can be found in the `sortBy` field values of the [available paremeters](../searching-entities/filtering-search-results.md#available-parameters).
|
||||
|
||||
Note that the default sorting is based on the `relevance` score of the search results.
|
||||
|
||||
Examples:
|
||||
|
||||
- Get research products published after `2020-01-01` and sort them by the publication date in descending order:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?fromPublicationDate=2020-01-01&sortBy=publicationDate DESC](https://api-beta.openaire.eu/graph/researchProducts?fromPublicationDate=2020-01-01&sortBy=publicationDate%20DESC)
|
||||
|
||||
- Get research products with the keyword `"COVID-19"` and sort them by their (citation-based) popularity:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=popularity DESC](https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=popularity%20DESC)
|
||||
|
||||
Note that you can combine multiple sorting conditions by separating them with a comma.
|
||||
|
||||
Example:
|
||||
|
||||
- Get research products with the keyword `"COVID-19"` and sort them by their publication date in ascending order and then by their popularity in descending order:
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=publicationDate ASC,popularity DESC](https://api-beta.openaire.eu/graph/researchProducts?search=COVID-19&sortBy=publicationDate%20ASC,popularity%20DESC)
|
||||
|
||||
## Paging
|
||||
|
||||
The OpenAIRE Graph API supports basic and cursor-based pagination. In basic pagination, `page` and `pageSize` parameters are used, enabling you to specify which part of the result set to retrieve and how many results per page.
|
||||
|
||||
### Offset-based paging
|
||||
Offset-based paging should be used to retrieve a small dataset only (up to 10000 records).
|
||||
* `page`: Specifies the page number of the results you want to retrieve. Page numbering starts from 1.
|
||||
|
||||
* `pageSize`: Defines the number of results to be returned per page. This helps limit the amount of data returned in a single request, making it easier to process.
|
||||
|
||||
Example:
|
||||
- Get the top 10 most influential research products that contain the phrase "knowledge graphs":
|
||||
|
||||
[https://api-beta.openaire.eu/graph/researchProducts?search="knowledge graphs"&page=1&pageSize=10&sortBy=influence DESC](https://api-beta.openaire.eu/graph/researchProducts?search=%22knowledge%20graphs%22&page=1&pageSize=10&sortBy=influence%20DESC)
|
||||
|
||||
response:
|
||||
```json
|
||||
{
|
||||
header: {
|
||||
numFound: 36818386,
|
||||
maxScore: 1,
|
||||
queryTime: 21,
|
||||
page: 1,
|
||||
pageSize: 10
|
||||
},
|
||||
results: [
|
||||
...
|
||||
]
|
||||
}
|
||||
```
|
||||
|
||||
### Cursor-based paging
|
||||
Cursor should be used when it is required to retrieve a big dataset (more than 10000 records).
|
||||
* `cursor`: Cursor-based pagination. Initial value: `cursor=*`.
|
||||
|
||||
Example:
|
||||
- [https://api-beta.openaire.eu/graph/researchProducts?search="knowledge graphs"&pageSize=10&cursor=*&sortBy=influence DESC](https://api-beta.openaire.eu/graph/researchProducts?search=%22knowledge%20graphs%22&pageSize=10&cursor=*&sortBy=influence%20DESC)
|
||||
|
||||
response:
|
||||
```json
|
||||
{
|
||||
header: {
|
||||
numFound: 36818386,
|
||||
maxScore: 1,
|
||||
queryTime: 21,
|
||||
pageSize: 10,
|
||||
nextCursor: "AoI/D2M2NGU1YjVkNTQ4Nzo6NjlmZTBmNjljYzM4YTY1MjI5YjM3ZDRmZmIyMTU1NDAIP4AAAA=="
|
||||
},
|
||||
results: [
|
||||
...
|
||||
]
|
||||
}
|
||||
```
|
||||
Use `nextCursor` value, to get the next page of results.

# Response metadata format
|
||||
|
||||
In this page, we elaborate on the metadata response format, as well as response headers and errors.
|
||||
|
||||
## Main response
|
||||
|
||||
The OpenAIRE Search API supports the following types of response formats:
|
||||
|
||||
* XML
|
||||
* JSON
|
||||
* CSV
|
||||
* TSV
|
||||
|
||||
In the next paragraphs, we elaborate on the respective metadata formats.
|
||||
|
||||
### XML/JSON
|
||||
|
||||
The default format of delivered records is oaf (OpenAIRE Format - current version 1.0):
|
||||
|
||||
* XML schema: https://www.openaire.eu/schema/1.0/oaf-1.0.xsd

|
||||
|
||||
|
||||
### CSV/TSV
|
||||
|

# Search API
|
||||
|
||||
The Search API allows developers to access metadata records of the OpenAIRE Graph by performing queries over research products (i.e., publications, data, software, other research products), and projects.
|
||||
|
||||
The API is intended for metadata discovery and exploration only, hence it does not provide access to the whole information space: the number of total results returned by one query is limited to 10,000.
|
||||
|
||||
For accessing the whole graph, developers are encouraged to use the [OpenAIRE full Graph dataset](../../downloads/full-graph).

# Versions & changelog
|
||||
|
||||
## Versioning
|
||||
|
||||
Our versioning policy follows the [Semantic Versioning specification](https://semver.org/).
|
||||
In our case, given a version `MAJOR.MINOR.PATCH`, we increment the:
|
||||
|
||||
* `MAJOR` version when the data model of the Graph changes
|
||||
* `MINOR` version when the pipeline (e.g., different deduplication method, different implementation for an enrichment process) or major data sources change
|
||||
* `PATCH` version when the graph data are updated
|
||||
|
||||
## Changelog
|
||||
|
||||
This section documents all notable changes for each graph version.

Its main entities are described in brief below:
|
||||
|
||||
* [Research products](./entities/research-product) represent the outcomes (or products) of research activities.
|
||||
* [Data sources](./entities/data-source) are the sources from which the metadata of graph objects are collected.
|
||||
* [Organizations](./entities/organization) correspond to companies or research institutions involved in projects,
|
||||
* [Results](entities/result) represent the outcomes of research activities.
|
||||
* [Data Sources](entities/data-source) are the resources used to collect metadata for the graph objects
|
||||
* [Organizations](entities/organization) correspond to companies or research institutions involved in projects,
|
||||
responsible for operating data sources or consisting the affiliations of Product creators.
|
||||
* [Projects](./entities/project) are research project grants funded by a Funding Stream of a Funder.
|
||||
* [Communities](./entities/community) are groups of people with a common research intent (e.g. research infrastructures, university alliances).
|
||||
* Persons correspond to individual researchers who are involved in the design, creation or maintenance of research products. Currently, this is a non-materialized entity type in the Graph, which means that the respective metadata (and relationships) are encapsulated in the author field of the respective research products.
|
||||
* [Projects](entities/project) are research projects funded by a Funding Stream of a Funder.
|
||||
* [Communities](entities/community) are groups of people with a common research intent.

OpenAIRE entity instances are created out of data collected from various data sources of different kinds, such as publication repositories, research data archives, CRIS systems, funder databases, etc. Data sources export information packages (e.g., XML records, HTTP responses, RDF data, JSON) that may contain information on one or more of such entities and possibly relationships between them.

OpenAIRE entity instances are created out of data collected from various data sources of different kinds, such as publication repositories, dataset archives, CRIS systems, funder databases, etc. Data sources export information packages (e.g., XML records, HTTP responses, RDF data, JSON) that may contain information on one or more of such entities and possibly relationships between them.
|
||||
|
||||
For example, a metadata record about a project carries information for the creation of a Project entity and its participants (as Organization entities). It is important, once each piece of information is extracted from such packages and inserted into the OpenAIRE information space as an entity, for such pieces to keep provenance information relative to the originating data source. This is to give visibility to the data source, but also to enable the reconstruction of the very same piece of information if problems arise.

## CitationImpact
|
||||
|
||||
The different citation-based impact indicators as computed by [BIP!](https://bip.imsi.athenarc.gr/).
|
||||
|
||||
|
||||
### indicator
|
||||
_Type: String • Cardinality: ONE_
|
||||
|
||||
The name of indicator; it can be either one of:
|
||||
* `influence`: it reflects the overall/total (citation-based) impact of an article in the research community at large, based on the underlying citation network (diachronically).
|
||||
* `citationCount`: it is an alternative to the "Influence" indicator, which also reflects the overall/total (citation-based) impact of an article in the research community at large, based on the underlying citation network (diachronically).
|
||||
* `popularity`: it reflects the "current" (citation-based) impact/attention (the "hype") of an article in the research community at large, based on the underlying citation network.
|
||||
* `impulse`: it reflects the initial momentum of an article directly after its publication, based on the underlying citation network.
|
||||
|
||||

By sustaining the current successful infrastructure, comprised of a human network and robust technical services, it consolidates its achievements while working to shift the momentum among its communities to Open Science, aiming to be a trusted e-Infrastructurewithin the realms of the European Open Science Cloud.In this next phase, OpenAIRE-Advance strives to empower its National Open Access Desks (NOADs) so they become a pivotal part within their own national data infrastructures, positioningOA and open science onto national agendas. The capacity building activities bring together experts ontopical task groups in thematic areas(open policies, RDM, legal issues, TDM), promoting a train the trainer approach, strengthening and expanding the pan-European Helpdesk with support and training toolkits, training resources and workshops.It examines key elements of scholarly communication, i.e., co-operative OA publishing and next generation repositories, to develop essential building blocks of the scholarly commons.On the technical level OpenAIRE-Advance focuses on the operation and maintenance of the OpenAIRE technical TRL8/9 services,and radically improvesthe OpenAIRE services on offer by: a) optimizing their performance and scalability, b) refining their functionality based on end-user feedback, c) repackagingthem into products, taking a professional marketing approach with well-defined KPIs, d)consolidating the range of services/products into a common e-Infra catalogue to enable a wider uptake.OpenAIRE-Advancesteps up its outreach activities with concrete pilots with three major RIs,citizen science initiatives, and innovators via a rigorous Open Innovation programme. Finally, viaits partnership with COAR, OpenAIRE-Advance consolidatesOpenAIRE’s global roleextending its collaborations with Latin America, US, Japan, Canada, and Africa."

### publicationDate
|
||||
_Type: String • Cardinality: ONE_
|
||||
|
||||
Main date of the research product: typically the publication or issued date. In case of a research product with different versions with different dates, the date of the research product is selected as the most frequent well-formatted date. If not available, then the most recent and complete date among those that are well-formatted. For statistics, the year is extracted and the research product is counted only among the research products of that year. Example: Pre-print date: 2019-02-03, Article date provided by repository: 2020-02, Article date provided by Crossref: 2020, OpenAIRE will set as date 2019-02-03, because it’s the most recent among the complete and well-formed dates. If then the repository updates the metadata and set a complete date (e.g. 2020-02-12), then this will be the new date for the research product because it becomes the most recent most complete date. However, if OpenAIRE then collects the pre-print from another repository with date 2019-02-03, then this will be the “winning date” because it becomes the most frequent well-formatted date.

The following table lists all the possible relation semantics found in the Graph Dataset.
|
||||
|
||||
Note: the labels used to specify the semantic of the relationships are (for the large) inherited from the [DataCite metadata kernel](https://schema.datacite.org/meta/kernel-4.4/doc/DataCite-MetadataKernel_v4.4.pdf), which provides a description for them.

OpenAIRE aggregates metadata records describing objects of the research life-cycle from content providers compliant to the [OpenAIRE guidelines](https://guidelines.openaire.eu/) and from entity registries (i.e. data sources offering authoritative lists of entities, like [OpenDOAR](https://v2.sherpa.ac.uk/opendoar/), [re3data](https://www.re3data.org/), [DOAJ](https://doaj.org/), and various funder databases). After collection, metadata are transformed according to the OpenAIRE internal metadata model, which is used to generate the final OpenAIRE Graph, accessible from the [OpenAIRE EXPLORE portal](https://explore.openaire.eu) and the [APIs](https://graph.openaire.eu/develop/).
|
||||
|
||||
The transformation process includes the application of cleaning functions whose goal is to ensure that values are harmonised according to a common format (e.g. dates as YYYY-MM-dd) and, whenever applicable, to a common controlled vocabulary. The controlled vocabularies used for cleansing are accessible at [api.openaire.eu/vocabularies](https://api.openaire.eu/vocabularies/). Each vocabulary features a set of controlled terms, each with one code, one label, and a set of synonyms. If a synonym is found as field value, the value is updated with the corresponding term.
|
||||
In addition, the OpenAIRE Graph is extended with other relevant scholarly communication sources that need special handling, either because they do not strictly follow the OpenAIRE Guidelines or due to the vast amount of data of data they offer (e.g. DOIBoost, that merges Crossref, ORCID, Microsoft Academic Graph, and Unpaywall).
|
||||
Also, the OpenAIRE Graph is extended with other relevant scholarly communication sources that do not follow the OpenAIRE Guidelines and/or are too large to be integrated via the “normal” aggregation mechanism: DOIBoost (which merges Crossref, ORCID, Microsoft Academic Graph, and Unpaywall).

OpenAIRE collects metadata records from more than 70K scholarly communication sources from all over the world, including Open Access institutional repositories, data archives, journals. All the metadata records (i.e. descriptions of research products) are put together in a data lake, together with records from Crossref, Unpaywall, ORCID, Grid.ac, and information about projects provided by national and international funders. Dedicated inference algorithms applied to metadata and to the full-texts of Open Access publications enrich the content of the data lake with links between research results and projects, author affiliations, subject classification, links to entries from domain-specific databases. Duplicated organisations and results are identified and merged together to obtain an open, trusted, public resource enabling explorations of the scholarly communication landscape like never before.

|
||||
### Collection import
|
||||
|
||||
The nodes in the graph represent entities of different types. This phase is responsible for identifying all the nodes with a given type and make them available to the subsequent phases representing them in the deduplication record model.
|
||||
|
||||
### Candidate identification (clustering)
|
||||
|
||||
Clustering is a common heuristics used to overcome the N x N complexity required to match all pairs of objects to identify the equivalent ones. The challenge is to identify a [clustering function](./clustering-functions) that maximizes the chance of comparing only records that may lead to a match, while minimizing the number of records that will not be matched while being equivalent. Since the equivalence function is to some level tolerant to minimal errors (e.g. switching of characters in the title, or minimal difference in letters), we need this function to be not too precise (e.g. a hash of the title), but also not too flexible (e.g. random ngrams of the title). On the other hand, reality tells us that in some cases equality of two records can only be determined by their PIDs (e.g. DOI) as the metadata properties are very different across different versions and no [clustering function](./clustering-functions) will ever bring them into the same cluster.

||||

@ -34,14 +26,3 @@ To further limit the number of comparisons, a sliding window mechanism is used:
|
|||
### Duplicates grouping (transitive closure)
|
||||
|
||||
Once the similarity relations between pairs of records are drawn, the groups of equivalent records are obtained (transitive closure, i.e. “mesh”). From such sets a new representative object is obtained, which inherits all properties from the merged records and keeps track of their provenance.
|
||||
|
||||
### Relation redistribution
|
||||
|
||||
Relations involved in nodes identified as duplicated are eventually marked as virtually deleted and used as template for creating a new relation pointing to the new representative record.
|
||||
Note that nodes and relationships marked as virtually deleted are not exported.

The decision tree is almost identical to the publication decision tree, with the only exception of the *instance type check* stage. Since such type of record does not have a relatable instance type, the check is not performed and the decision tree node is skipped.

# Enrichment
|
||||
|
||||
## Mining
|
||||
|
||||
The OpenAIRE Graph is enriched by links mined by OpenAIRE’s full-text mining algorithms that scan the plaintexts of publications for funding information, references to datasets, software URIs, accession numbers of bioetities, and EPO patent mentions. Custom mining modules also link research objects to specific research communities, initiatives and infrastructures. In addition, other inference modules provide content-based document classification, document similarity, citation matching, and author affiliation matching.
|
||||
|
||||
**Project mining** in OpenAIRE text mines the full-texts of publications in order to extract matches to funding project codes/IDs. The mining algorithm works by utilising (i) the grant identifier, and (ii) the project acronym (if available) of each project. The mining algorithm: (1) Preprocesses/normalizes the full-texts using several functions, which depend on the characteristics of each funder (i.e., the format of the grant identifiers), such as stopword and/or punctuation removal, tokenization, stemming, converting to lowercase; then (2) String matching of grant identifiers against the normalized text is done using database techniques; and (3) The results are validated and cleaned using the context near the match by looking at the context around the matched ID for relevant metadata and positive or negative words/phrases, in order to calculate a confidence value for each publication-->project link. A confidence threshold is set to optimise high accuracy while minimising false positives, such as matches with page or report numbers, post/zip codes, parts of telephone numbers, DOIs or URLs, accession numbers. The algorithm also applies rules for disambiguating results, as different funders can share identical project IDs; for example, grant number 633172 could refer to H2020 project EuroMix but also to Australian-funded NHMRC project “Brain activity (EEG) analysis and brain imaging techniques to measure the neurobiological effects of sleep apnea”. Project mining works very well and was the first Text & Data Mining (TDM) service of OpenAIRE. Performance results vary from funder to funder but precision is higher than 98% for all funders and 99.5% for EC projects. Recall is higher than 95% (99% for EC projects), when projects are properly acknowledged using project/grant IDs.
|
||||
|
||||
**Dataset extraction** runs on publications full-texts as described in “High pass text-filtering for Citation matching”, TPDL 2017[1]. In particular, we search for citations to datasets using their DOIs, titles and other metadata (i.e., dates, creator names, publishers, etc.). We extract parts of the text which look like citations and search for datasets using database join and pattern matching techniques. Based on the experiments described in the paper, precision of the dataset extraction module is 98.5% and recall is 97.4% but it is also probably overestimated since it does not take into account corruptions that may take place during pdf to text extraction. It is calculated on the extracted full-texts of small samples from PubMed and arXiv.
|
||||
|
||||
**Software extraction** runs also on parts of the text which look like citations. We search the citations for links to software in open software repositories, specifically github, sourceforge, bitbucket and the google code archive. After that, we search for links that are included in Software Heritage (SH, https://www.softwareheritage.org) and return the permanent URL that SH provides for each software project. We also enrich this content with user names, titles and descriptions of the software projects using web mining techniques. Since software mining is based on URL matching, our precision is 100% (we return a software link only if we find it in the text and there is no need to disambiguate). As for recall rate, this is not calculable for this mining task. Although we apply all the necessary normalizations to the URLs in order to overcome usual issues (e.g., http or https, existence of www or not, lower/upper case), we do not calculate cases where a software is mentioned using its name and not by a link from the supported software repositories.
|
||||
|
||||
**For the extraction of bio-entities**, we focus on Protein Data Bank (PDB) entries. We have downloaded the database with PDB codes and we update it regularly. We search through the whole publication’s full-text for references to PDB codes. We apply disambiguation rules (e.g., there are PDB codes that are the same as antibody codes or other issues) so that we return valid results. Current precision is 98%. Although it's risky to mention recall rates since these are usually overestimated, we have calculated a recall rate of 98% using small samples from pubmed publications. Moreover, our technique is able to identify about 30% more links to proteins than the ones that are tagged in Pubmed xmls.
|
||||
|
||||
**Other text-mining modules** include mining for links to EPO patents, or custom mining modules for linking research objects to specific research communities, initiatives and infrastructures, e.g. COVID-19 mining module. Apart from text-mining modules, OpenAIRE also provides a document classification service that employs analysis of free text stemming from the abstracts of the publications. The purpose of applying a document classification module is to assign a scientific text one or more predefined content classes. In OpenAIRE, the currently used taxonomies are arXiv, MeSH (Medical Subject Headings), ACM and DDC (Dewey Decimal Classification, or Dewey Decimal System).
|
||||
|
||||
## Bulk Tagging/Deduction
|
||||
|
||||
The Deduction process (also known as “bulk tagging”) enriches each record with new information that can be derived from the existing property values.
|
||||
|
||||
As of September 2020, three procedures are in place to relate a research product to a research initiative, infrastructure (RI) or community (RC) based on:
|
||||
|
||||
* subjects (2.7M results tagged)
|
||||
|
||||
* Zenodo community (16K results tagged)
|
||||
|
||||
* the data source it comes from (250K results tagged)
|
||||
|
||||
The list of subjects, Zenodo communities and data sources used to enrich the products are defined by the managers of the community gateway or infrastructure monitoring dashboard associated with the RC/RI.
|
||||
|
||||
## Propagation
|
||||
|
||||
This process “propagates” properties and links from one product to another if between the two there is a “strong” semantic relationship.
|
||||
|
||||
As of September 2020, the following procedures are in place:
|
||||
Propagation of the property “country” to results from institutional repositories: e.g. publication collected from an institutional repository maintained by an italian university will be enriched with the property “country = IT”.
|
||||
|
||||
* Propagation of links to projects: e.g. publication linked to project P “is supplemented by” a dataset D. Dataset D will get the link to project P. The relationships considered for this procedure are “isSupplementedBy” and “supplements”.
|
||||
|
||||
* Propagation of related community/infrastructure/initiative from organizations to products via affiliation relationships: e.g. a publication with an author affiliated with organization O. The manager of the community gateway C declared that the outputs of O are all relevant for his/her community C. The publication is tagged as relevant for C.
|
||||
|
||||
* Propagation of related community/infrastructure/initiative to related products: e.g. publication associated to community C is supplemented by a dataset D. Dataset D will get the association to C. The relationships considered for this procedure are “isSupplementedBy” and “supplements”.
|
||||
|
||||
* Propagation of ORCID identifiers to related products, if the products have the same authors: e.g. publication has ORCID for its authors and is supplemented by a dataset D. Dataset D has the same authors as the publication. Authors of D are enriched with the ORCIDs available in the publication. The relationships considered for this procedure are “isSupplementedBy” and “supplements”.

# Impact scores
|
||||
<span className="todo">TODO - add intro</span>
|
||||
|
||||
## Citation Count (CC)
|
||||
|
||||
This is the most widely used scientific impact indicator, which sums all citations received by each article. The citation count of a
|
||||
publication $i$ corresponds to the in-degree of the corresponding node in the underlying citation network: $s_i = \sum_{j} A_{i,j}$,
|
||||
where $A$ is the adjacency matrix of the network (i.e., $A_{i,j}=1$ when paper $j$ cites paper $i$, while $A_{i,j}=0$ otherwise).
|
||||
Citation count can be viewed as a measure of a publication's overall impact, since it conveys the number of other works that directly
|
||||
drew on it.
|
||||
|
||||
## "Incubation" Citation Count (iCC)
|
||||
|
||||
This measure is essentially a time-restricted version of the citation count, where the time window is distinct for each paper, i.e.,
|
||||
only citations $y$ years after its publication are counted (usually, $y=3$). The "incubation" citation count of a paper $i$ is
|
||||
calculated as: $s_i = \sum_{j,t_j \leq t_i+3} A_{i,j}$, where $A$ is the adjacency matrix and $t_j, t_i$ are the citing and cited paper's
|
||||
publication years, respectively. $t_i$ is cited paper $i$'s publication year. iCC can be seen as an indicator of a paper's initial momentum
|
||||
(impulse) directly after its publication.
|
||||
|
||||
## PageRank (PR)
|
||||
|
||||
Originally developed to rank Web pages, PageRank has been also widely used to rank publications in citation
|
||||
networks. In this latter context, a publication's PageRank
|
||||
score also serves as a measure of its influence. In particular, the PageRank score of a publication is calculated
|
||||
as its probability of being read by a researcher that either randomly selects publications to read or selects
|
||||
publications based on the references of her latest read. Formally, the score of a publication $i$ is given by:
|
||||
|
||||
$$
|
||||
s_i = \alpha \cdot \sum_{j} P_{i,j} \cdot s_j + (1-\alpha) \cdot \frac{1}{N}
|
||||
$$
|
||||
|
||||
where $P$ is the stochastic transition matrix, which corresponds to the column normalised version of adjacency
|
||||
matrix $A$, $\alpha \in [0,1]$, and $N$ is the number of publications in the citation network. The first addend
|
||||
of the equation corresponds to the selection (with probability $\alpha$) of following a reference, while the
|
||||
second one to the selection of randomly choosing any publication in the network. It should be noted that the
|
||||
score of each publication relies of the score of publications citing it (the algorithm is executed iteratively
|
||||
until all scores converge). As a result, PageRank differentiates citations based on the importance of citing
|
||||
articles, thus alleviating the corresponding issue of the Citation Count.
|
||||
|
||||
## RAM
|
||||
|
||||
RAM is essentially a modified Citation Count, where recent citations are considered of higher importance compared
|
||||
to older ones. Hence, it better captures the popularity of publications. This "time-awareness" of citations
|
||||
alleviates the bias of methods like Citation Count and PageRank against recently published articles, which have
|
||||
not had "enough" time to gather as many citations. The RAM score of each paper $i$ is calculated as follows:
|
||||
|
||||
$$
|
||||
s_i = \sum_j{R_{i,j}}
|
||||
$$
|
||||
|
||||
where $R$ is the so-called Retained Adjacency Matrix (RAM) and $R_{i,j}=\gamma^{t_c-t_j}$ when publication $j$ cites publication
|
||||
$i$, and $R_{i,j}=0$ otherwise. Parameter $\gamma \in (0,1)$, $t_c$ corresponds to the current year and $t_j$ corresponds to the
|
||||
publication year of citing article $j$.
|
||||
|
||||
## AttRank
|
||||
|
||||
AttRank is a PageRank variant that alleviates its bias against recent publications (i.e., it is tailored to capture popularity).
|
||||
AttRank achieves this by modifying PageRank's probability of randomly selecting a publication. Instead of using a uniform probability,
|
||||
AttRank defines it based on a combination of the publication's age and the citations it received in recent years. The AttRank score
|
||||
of each publication $i$ is calculated based on:
|
||||
|
||||
$$
|
||||
s_i = \alpha \cdot \sum_{j} P_{i,j} \cdot s_j
|
||||
+ \beta \cdot Att(i)+ \gamma \cdot c \cdot e^{-\rho \cdot (t_c-t_i)}
|
||||
$$
|
||||
|
||||
where $\alpha + \beta + \gamma =1$ and $\alpha,\beta,\gamma \in [0,1]$. $Att(i)$ denotes a recent attention-based score for publication $i$,
|
||||
which reflects its share of citations in the $y$ most recent years, $t_i$ is the publication year of article $i$, $t_c$ denotes the current
|
||||
year, and $c$ is a normalisation constant. Finally, $P$ is the stochastic transition matrix.

CERMINE is based on a modular workflow, whose architecture ensures that individual workflow steps can be maintained separately. As a result it is easy to perform evaluation, training, improve or replace one step implementation without changing other parts of the workflow. Most steps implementations utilize supervised and unsupervised machine-leaning techniques, which increases the maintainability of the system, as well as its ability to adapt to new document layouts.

* Basic structure extraction takes a PDF file on the input and produces a geometric hierarchical structure representing the document. The structure is composed of pages, zones, lines, words and characters. The reading order of all elements is determined. Every zone is labelled with one of four general categories: METADATA, REFERENCES, BODY and OTHER.

# Post cleaning

<!-- ## Vocabulary based cleaning -->
|
||||
At the very end of the processing pipeline, a step is dedicated to perform cleaning operations aimed at improving the overall quality of the data.
|
||||
The output of this final cleansing step is the final version of the OpenAIRE Graph.
|
||||
|
||||
## Vocabulary based cleaning
|
||||
|
||||
The aggregation processes run independently one from another and continuously. Each aggregation process, depending on the characteristics of the records exposed by the data source, makes use of one or more vocabularies to harmonise the values available in a given field.
|
||||
In this page, we describe the *vocabulary-based cleaning* operation performed to harmonise the data of the different data sources.
|
||||
A vocabulary is a data structure that defines a list of terms, and for each term defines a list of synonyms:

Each aggregation process applies vocabularies according to their definitions in a given moment of time, however, it could be the case that a vocabulary changes after the aggregation of one data source has finished, thus the aggregated content does not reflect the current status of the controlled vocabularies.
|
||||
|
||||
In addition, the integration of ScholeXplorer and DOIBoost and some enrichment processes applied on the raw and on the de-duplicated graph may introduce values that do not comply with the current status of the OpenAIRE controlled vocabularies. For these reasons, we included a final step of cleansing at the end of the workflow materialisation.
|
||||
|
||||
## Filtering
|
||||
|
||||
Bibliographic records that do not meet minimal requirements for being part of the OpenAIRE Graph are eliminated during this phase.
|
||||
Currently, the only criteria applied horizontally to the entire graph aims at excluding scientific results whose title is not meaningful for citation purposes.
|
||||
Then, different criteria are applied in the pre-processing of specific sub-collections:
|
||||
|
||||
* [Crossref filtering](/data-provision/aggregation/doiboost#crossref-filtering)
|
||||
|
||||
## Country cleaning
|
||||
|
||||
This phase is responsible for removing the country information from result records that match specific criteria. The need for this phase is driven by the fact that some datasources, although referred of national pertinence, they contain material that is not always related to the given country.

# Stats analysis
|
||||
|
||||
The OpenAIRE Graph is also processed by a pipeline for extracting the statistics and producing the charts for funders, research initiative, infrastructures, and policy makers that you can see on MONITOR. Based on the information available on the graph, OpenAIRE provides a set of indicators for monitoring the funding and research impact and the uptake of Open Science publishing practices, such as Open Access publishing of publications and datasets, availability of interlinks between research products, availability of post-print versions in institutional or thematic Open Access repositories, etc.

# Beginner's kit
|
||||
|
||||
The large size of the OpenAIRE Graph is a major impediment for beginners to familiarise with the underlying data model and explore its contents.
|
||||
Working with the Graph in its full size typically requires access to a huge distributed computing infrastructure which cannot be easily accessible to everyone.
|
||||
[The OpenAIRE Beginner’s Kit](https://doi.org/10.5281/zenodo.7490191) aims to address this issue. It consists of two components:

This version is not accompanied with public dataset files, hence the files in this section are based on [v6.0.0](/docs/6.0.0/) of the Graph. The current data are only exposed via the [OpenAIRE Graph API](https://graph.openaire.eu/develop/) and added-value services that are built on top of this version of the Graph (e.g., the [OpenAIRE Explore](https://explore.openaire.eu/)).

* A subset of the Graph composed of the research products published between 2022-06-29 and 2022-12-29, all the entities connected to them and the respective relationships.
|
||||
* A Zeppelin notebook that demonstrates how you can use PySpark to analyse the Graph and get answers to some interesting research questions. A guide to Apache Zeppelin can be found [here](https://docs.cloudera.com/HDPDocuments/HDP2/HDP-2.6.5/bk_zeppelin-component-guide/content/ch_overview.html).
