Affiliation-Matching Repository [aka AffRo]

This repository contains code for matching affiliation strings to ROR or/and OpenOrg IDs.

🚀 As it is still a work in progress, the repository may not always be up-to-date. However, I will incorporate improvements and bug fixes regularly.

Main files

  • helpers/create_input.py, helpers/matching.py, contain the main algorithm (preprocessing and matching phase, respectively).

Testing

  • test.ipynb

Description of the algorithm

Goal: Identify organizations inside a raw affiliation string and match the corresponding ROR ids.

Steps:

  • Preprocessing phase:
  1. Cleaning and stemming
  2. Keyword labeling and partitioning
  3. Partition pruning and string shortening
  • Matching phase:
  1. Candidate identification and refinement
  2. Results disambiguation

Basic parameters:

  1. Threshold for university related organizations (default 0.42).
  2. Threshold for other organizations (default 0.82).
  3. Context window for trimming text around the term "university" (default 3)
