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. Semantic results came from the SemanticVectors software package by Dominic Widdows
http://code.google.com/p/semanticvectors/ and have been used to 'blow up' an index query in a way Mr Libbrecht, my supervisor, described above. I wonder if my blog is an appropriate location for my thesis, so please feel free to redistribute it. http://www.twelve02.de/publications/jednoralski_bachelorthesis_latent_semantics_for_activemath.pdf Best Dominik Jednoralski 2009/3/18 Simon Willnauer <simon.willna...@googlemail.com> > Hi, > > On Wed, Mar 18, 2009 at 8:59 AM, Paul Libbrecht <p...@activemath.org> > wrote: > > 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 termC with their > > semantic-distance as a boost factor) > > - run query get results with higher rank for termA if found, then for > termB > > and termC > > > > My student Dominik Jednoralski has written a bachelor thesis on that. > > I'll forward the request to send you this. > If it is possible could you post a link where everybody can reach the > thesis of your student? > I guess it could be interesting for a couple of people on this list > and a benefit for your student as well. > > simon > > > > Join the semanticVectors' list where the original author also talks. > > > > paul > > > > > > Le 18-mars-09 à 08:34, nitin gopi a écrit : > > > >> hi Paul, I am new to this field of search engine.
