AbstractIn the article the review of methods for solving of information retrieval queries expansion problem is given. The formalized concept of a semantic context is entered. The semantic contexts model of natural language texts is offered. Properties of the offered model are considered and the method of its construction is proved. The algorithms of construction and application of associative model of semantic contexts for the decision of queries expansion problem by relevance feedback are resulted.
