# BM25Transformer

## About

This library transforms a [document-term matrix](https://en.wikipedia.org/wiki/Document-term_matrix) to a [Okapi/BM25](https://en.wikipedia.org/wiki/Okapi_BM25) representation.

API of this library inherits from [sklearn.feature\_extraction.text.TfidfTransformer](http://scikit-learn.org/stable/modules/generated/sklearn.feature_extraction.text.TfidfTransformer.html).
