It doesn't look too active, but you might check out: https://github.com/algoriffic/lsa4solr Otherwise, Mahout has some of the basis for it but you would have to do some work. On Aug 29, 2011, at 9:55 AM, zarrinkalam wrote: > hi, > > I want to use LSI for clustring ducuments indexed with luc

Zarrinkalam, have a look at semanticvectors. paul Le 29 août 2011 à 15:55, zarrinkalam a écrit : > hi, > > I want to use LSI for clustring ducuments indexed with lucene, I dont know > how, plz help me > > thanks, - To uns

Re: lsi as indexing algorithm with lucene

Hello all, following the link to SemanticVectors - related research there is this link:- Magnus Sahlgren. An introduction to random indexing. I would like to point out that Magnus Sahlgren has completed a PHd in this area which is both very readable

Re: lsi as indexing algorithm with lucene

Hi, I'm the guy who has written the bachelor on this. Sorry it took a while to publish it to the community, but I had to improve it before publishing. The topic of the thesis was to augment the Lucene-driven search facility of the Intelligent Tutoring System ActiveMath by latent semantics. Semanti

Re: lsi as indexing algorithm with lucene

Depending on your corpus, a semantic vector enabled search engine definitely is more semantic than one without. The general approach I have with these is: - get a query - expand each terms of the query with the fuzzification of semantic- vectors (e.g. if requested for termA, add termB and ter

Re: lsi as indexing algorithm with lucene

hi Paul, I am new to this field of search engine. My aim is to develop a semantic search engine. Initially I was trying to develop that by using LSI. But since it is patented that is why there are no many implementation attempts. I want to ask is it possible to create a search engine using lucene

Re: lsi as indexing algorithm with lucene

Nitin, LSI is patented so it's not been a flurry of implementation attempts. However, SemanticVectors is a library that does similar approaches to LSA/LSI for indexing and is based on Lucene's term-vectors. paul Le 18-mars-09 à 07:09, nitin gopi a écrit : hi all , has any body tried to us
