Subject Re: [ANN] word2vec for Lucene
Date Thu, 20 Nov 2014 15:28:53 GMT
Hi Koji,

Semantic vectors is here: http://code.google.com/p/semanticvectors/

It is a project that has been around for a number of years and used by many
people (including me
http://zzzoot.blogspot.com/2009/07/project-torngat-building-large-scale.html
).

If you could compare and contrast word2vec with Semantic Vectors, this
would allow many of us to understand where/when we might want to use
word2vec.

Thank-you,
Glen
