+# Data model
+
+The OpenAIRE Research Graph comprises several types of entities and relationships among them.
+
+The latest version of the JSON schema can be found on [Bulk downloads](../download).
+
+![Data mode](./assets/data-model.png)
+
+The figure above, presents the graph's data model. 
+Its main entities are described in brief below:
+
+* Research Products represent the outcomes of research activities.
+* Organizations correspond to companies or research institutions involved in projects,
+responsible for operating data sources or consisting the affiliations of Product creators.
+* Funders (e.g. EC, Wellcome Trust) are agencies responsible for a list of Funding Streams.
+* Funding Streams represent investments (funding actions) from Funders (e.g. FP7 or H2020).
+* Projects are research projects funded by a Funding Stream of a Funder.
+* Data Sources are the resources used to collect metadata for the graph objects

+# 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.
