Latent Semantic Analysis (LSA)


  • (LSA) a statistical method for finding the underlying dimensions of correlated terms. For example, words like law, lawyer, attorney, lawsuit, etc. All share some meaning. The presence of any one of them in a document could be recognized as indicating something consistent about the topic of the document. Latent Semantic Analysis uses statistics to allow the system to exploit these correlations for concept searching and clustering.  1
