Paper-Reviewer Matcher

A python package for paper-reviewer matching algorithm based on topic modeling and linear programming. The algorithm is implemented based on this article). This package solves problem of assigning paper to reviewers with constrains by solving linear programming problem. We minimize global distance between papers and reviewers in topic space (e.g. topic modeling can be Principal component, Latent Semantic Analysis (LSA), etc.).

Here is a diagram of problem setup and how we solve the problem.

Mind-Match Command Line

Mind-Match is a session we run at Cognitive Computational Neuroscience (CCN) conference. We use a combination of topic modeling and linear programming to solve optimal matching problem. To run example Mind-Match algorithm on sample of 500 people, you can clone the repository and run the following

python mindmatch.py data/mindmatch_example.csv --n_match=6 --n_trim=50

in the root of this repo. This should produce a matching output output_match.csv in this relative location. However, when people get much larger this script takes quite a long time to run. We use pre-cluster into groups before running the mind-matching to make the script runs faster. Below is an example script for pre-clustering and mind-matching on all data:

python mindmatch_cluster.py data/mindmatch_example.csv --n_match=6 --n_trim=50 --n_clusters=4

Example script for the conferences

Here, I include a recent scripts for our Mind Matching session for CCN conference.

• ccn_mind_matching_2019.py contains script for Mind Matching session (match scientists to scientists) for CCN conference
• ccn_paper_reviewer_matching.py contains script for matching publications to reviewers for CCN conference, see example of CSV files in data folder

The code makes the distance metric of topics between incoming papers with reviewers (for ccn_paper_reviewer_matching.py) and between people with people (for ccn_mind_matching_2019). We trim the metric so that the problem is not too big to solve using or-tools. It then solves linear programming problem to assign the best matches which minimize the global distance between papers to reviewers. After that, we make the output that can be used by the organizers of the CCN conference -- pairs of paper and reviewers or mind-matching schedule between people to people in the conference. You can see of how it works below.

Dependencies

Use pip to install dependencies

pip install -r requirements.txt

Please see Stackoverflow if you have a problem installing or-tools on MacOS. You can use pip to install protobuf before installing or-tools

pip install protobuf==3.0.0b4
pip install ortools

for Python 3.6,

pip install --user --upgrade ortools
