Publisher's Synopsis
It is impossible to imagine the modern world without the Internet - a global network that has become not only a source of entertainment, but also an important tool for work and learning. The World Wide Web, which contains an ever-growing huge amount of dynamically changing information, is developing at an unprecedentedly rapid pace. Searching for information in this environment is a big problem because of the huge volume, unsystematized, chaotic, etc. In order to somehow organize this continuous flow of data, and most importantly, to enable users of the Web to find the necessary information, special search engines were created, the efficiency and effectiveness of which currently leaves much to be desired. For this reason, it is of constant interest to improve methods and algorithms for information retrieval in a large information array. On this basis, the dissertation work is devoted to the topical issue of research of models and methods of improving the efficiency of the search process in the Internet.
