Collaboration and Topic Switches      

Official code repository for the paper "Collaboration and Topic Switches in Science" by Sara Venturini¹, Satyaki Sikdar¹, Francesco Rinaldi, Francesco Tudisco, and Santo Fortunato.

Data preprocessing

1. Create the topic-switch conda environment from environment.yml by running

conda env create -f environment.yml

2. Create data directories by executing the following command:

mkdir -p data/Physics; mkdir -p data/CS; mkdir -p data/BioMed

3. Download the OpenAlex slices from Zenodo inside data/{FIELD} directories. Eg: Physics.zip should be in data/Physics.

4. Extract the zipped slices, so you should have the following files inside data/{FIELD}: works.parquet, works_authorships.parquet, works_concepts.parquet, and works_referenced_works.parquet.

Running the experiments

• Run notebooks/ExperimentI.pynb or notebooks/ExperimentII.pynb
• More info coming soon..

Analysis and generate plots

• Run notebooks/analysis.ipynb
• More info coming soon..
