This repository contains the resources and code for measuring gender bias in the result list of Information Retrieval models, as explained in the paper: https://arxiv.org/abs/2005.00372

• resources/queries_gender_annotated.csv: Annotation results of the related gender of queries.
• resources/wordlist_genderspecific.txt: List of gender specific words.

Follow the code in step1_calculate_bias_documents.ipynb for calculating the gender bias of each document in collection. At the beginning of the notebook, set collection_path to the path of the collection with TSV format. For MS MARCO collection, this should refer to the collection.tsv file. The code does not apply any particular pre-processing to the text unless converting it to lower case. It is suggested that you apply the required pre-processing before hand.

Using the pre-calculated document biases, step2_calculate_bias_runs.ipynb calculates gender bias scores for each query for the given retrieval run files.

• step3_bias_metrics.ipynb calculates the final gender bias metrics for each experiment.

The paper will appear in the proceedings of SIGIR 2020. Reference to the arXiv version:
