Add BM25 Scoring to Lucene
--------------------------
Key: LUCENE-2091
URL: https://issues.apache.org/jira/browse/LUCENE-2091
Project: Lucene - Java
Issue Type: New Feature
Components: contrib/*
Reporter: Yuval Feinstein
Priority: Minor
Fix For: 3.1
http://nlp.uned.es/~jperezi/Lucene-BM25/ describes an implementation of
Okapi-BM25 scoring in the Lucene framework,
as an alternative to the standard Lucene scoring (which is a version of mixed
boolean/TFIDF).
I have refactored this a bit, added unit tests and improved the runtime
somewhat.
I would like to contribute the code to Lucene under contrib.
