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 assumes that words that are close in meaning will occur in similar pieces of text. http://en.wikipedia.org/wiki/Latent_semantic_analysis
