Hi Nagendra, really cool topic. I'm really interested in discover more information about the three similraties algorithm you offer ( Term Similarity, Document Similiraty and Term In Document Similarity). I was looking for more details and explanations behind your Ranking Algorithm. Where could i start ? I'm really curious of the LSA Model used and also low level algorithm and science applied. Good work !
