-------------------------------------
Summary: some improvements about the latent semantic search, more
details are in Description part
Key: LUCENE-4458
URL: https://issues.apache.org/jira/browse/LUCENE-4458
Project: Lucene - Core
Issue Type: Improvement
Components: core/query/scoring
Reporter: wang jianping
Hi,all,Recently I invented a new ranking algorithm inspired by the theory of
spread activation and probabilistic model, which can find the latent semantic
relationship between docs and terms and is almost linear time, and I took one
afternoon to code and implement this algorithm. And the testing result shows
that the speed of this algorithm is much faster than the famous Latent Semantic
Analysis algorithm, and the affect is almost as good as the LSA. I wanna share
my idea to all of you and add this algorithm to the Lucene project.
