A number of electronic documents grows much faster than a human is able to deal with. The information retrieval methods help to identify documents likely containing a given information. The selection of documents is based on keywords, that are assigned to characterize document content and used to specify the aims of user search. To achieve this aim, information retrieval utilizes the methods of linear algebra that work with the vector model, statistical and probability methods, methods of computational linguistics or classification and clustering methods of artificial intelligence.
