Subject [jira] Created: (LUCENE-2091) Add BM25 Scoring to Lucene
Date Mon, 23 Nov 2009 13:36:39 GMT
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.
