  Pyserini is a Python toolkit for reproducible information retrieval research with sparse and dense representations. Retrieval using sparse representations is provided via integration with our group's Anserini IR toolkit, which is built on Lucene. Retrieval using dense representations is provided via integration with Facebook's Faiss library.

  Pyserini is a Python toolkit for **reproducible information retrieval research**, offering a unified interface for **first-stage retrieval** with both **sparse (via Anserini/Lucene) and dense (via Faiss) representations**. It provides a self-contained, easy-to-use environment for experimenting with and evaluating IR systems on standard test collections.

  ## ✨ Why Pyserini?
  Pyserini stands out as a **unified Python toolkit** specifically designed for **reproducible information retrieval research**. Unlike general machine learning libraries, Pyserini integrates powerful sparse (Anserini/Lucene) and dense (Faiss) retrieval methods into a single, easy-to-use package. It provides prebuilt indexes, queries, and evaluation scripts for many standard IR test collections, making it ideal for researchers and practitioners focused on robust, verifiable IR experiments.
