  == Latent Semantic Analysis by SVD ==
  Latent semantic analysis (LSA) is a technique in natural language processing, in particular
in vectorial semantics, of analyzing relationships between a set of documents and the terms
they contain by producing a set of concepts related to the documents and terms. LSA was patented
in 1988 by Scott Deerwester, Susan Dumais, George Furnas, Richard Harshman, Thomas Landauer,
Karen Lochbaum and Lynn Streeter. In the context of its application to information retrieval,
it is sometimes called latent semantic indexing (LSI). -- wikipedia
