[GSoC] Implementing State of the Art Ranking for Lucene
-------------------------------------------------------
Key: LUCENE-2959
URL: https://issues.apache.org/jira/browse/LUCENE-2959
Project: Lucene - Java
Issue Type: New Feature
Components: Examples, Javadocs, Query/Scoring
Reporter: David Mark Nemeskey
Attachments: proposal.pdf
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.
