Models and Algorithms of Information Retrieval in a Multilingual Environment on the Basis of Thematic and Dynamic Text Corpora

Models and algorithms of information retrieval in the global and local computer networks on the basis of thematic and dynamic text corpora are proposed in this article. The developed algorithms provide the effectiveness of documents information retrieval and notable for universality, i. e., for the independence from topics. Information system adjustment to a particular data domain can be fully automated, it adds up to the creation of a respective thematic text corpus and an actualization of dictionaries of the knowledge database.
