[jira] [Updated] (LUCENE-3220) Implement various ranking models as
Similarities
[ https://issues.apache.org/jira/browse/LUCENE-3220?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
David Mark Nemeskey updated LUCENE-3220:
----------------------------------------
Description:
With [LUCENE-3174|https://issues.apache.org/jira/browse/LUCENE-3174] done, we can finally work on implementing the standard ranking models. Currently DFR, BM25 and LM are on the menu.
TODO:
* {{EasyStats}}: contains all statistics that might be relevant for a ranking algorithm
* {{EasySimilarity}}: the ancestor of all the other similarities. Hides the DocScorers and as much implementation detail as possible
* _BM25_: the current "mock" implementation might be OK
* _LM_
* _DFR_
Done:
