BERT Reranker for MS-MARCO Document Ranking

Model description

A text reranker trained for BM25 retriever on MS MARCO document dataset.

Intended uses & limitations

It is possible to work with other retrievers like but using aligned BM25 works the best.

We used anserini toolkit's BM25 implementation and indexed with tuned parameters (k1=3.8, b=0.87) following this instruction.

How to use

See our project repo page.
