David Mark Nemeskey updated LUCENE-2959:
----------------------------------------
Description:
Lucene employs the Vector Space Model (VSM) to rank documents, which compares
unfavorably to state of the art algorithms, such as BM25. Moreover, the
architecture is
tailored specically to VSM, which makes the addition of new ranking functions a
non-
trivial task.
This project aims to bring state of the art ranking methods to Lucene and to
implement a
query architecture with pluggable ranking functions.
The wiki page for the project can be found at
http://wiki.apache.org/lucene-java/SummerOfCode2011ProjectRanking.
