Latent Semantic Indexing (LSI) also called Latent semantic analysis is a mathematical method that was developed so that the accuracy of retrieving information can be improved. It helps in finding out the hidden(latent) relationship between the words(semantics) by producing a set of various concepts related to the terms of a sentence to improve the information understanding. The technique used for the purpose is called Singular value decomposition. It is generally useful for working on small sets of static documents.
