Hello group,
I would like to implement Relevance Feedback functionality for my system.
From the privious discussion in this group I know that this is not implemented
in Lucene.
We all know that Relevance Feedback has two fields, which are
1) Term Reweighting
2) Query Expansion
I am
Hello all,
oh, I just found a mail from Doug where he wrote that Dmitry Serebrennikov
developed something who provides Document vector access:

Hello Group of Lucene users,
query reformulation is understood as a effective way to improve retrieval
power significantly. The theory teaches us that it consists of two basic steps:
a) Query expansion (with new terms)
b) Reweighting of the terms in the expanded query
User relevance feedback
. term reweighting happens by using term boost. how much you boost by is an
open question.

Also, has anyone got hold of the extension

Dmitry Serebrennikov [[EMAIL PROTECTED]] has implemented a substantial
extension to Lucene which should help folks doing this sort of research
feedback. I haven't seen any mention of manual or automated query
expansion or user relevance feedback in the Lucene documentation or FAQs.
Does anyone have any experience with these processes in general and/or
specifically with Lucene? If so, did you have to reimplement Lucene's

This makes sense to me. I'm looking to do something similar but add in
a final step of allowing the user to select which terms (of those that
