Two-Sided Fairness for Personalized Recommendations in Two-Sided Platforms

Two-Sided Fairness for Personalized Recommendations in Two-Sided Platforms

Running FairRec

python fairrec_algorithm.py google_local_fact.csv 10 0.5

There are three arguments here.

• path to csv file with relevance scores (rows: customers, columns: producers) like google_local_fact.csv above.
  
• size of recommendation or k like 10 above.
  
• value of α (our producer-side guarantee will be α×MMS. The value of α can be in between 0 and 1) like 0.5 above.

It saves the recommendations in zipped pickle file (dictionary format { customer : list_of_recommended_products }).

Relevance Scores

You can use the relevance scores estimated in your dataset in csv format (rows: customers, columns: producers) for your application scenario. Alternatively you can test with ours. The relevance scores calculated for the datasets (used in the paper) can be found in the following links in zipped csv format.

• GL-CUSTOM : Custom relevance function on Google Local ratings data.
• GL-FACT : Relevance scores from latent embedding based factorization on Google Local ratings data.
• LF : Relevance scores from latent embedding based factorization on Last.fm data.
