FIELD: information technology.

SUBSTANCE: method of constructing a semantic model of a document consists of two basic steps. At the first step, ontology is extracted from external information resources that contain descriptions of separate objects of the object region. At the second step, text information of the document is tied to ontology concepts and a semantic model of the document is constructed. The information sources used are electronic resources, both tied and untied to the structure of hypertext links. First, all terms of the document are separated and tied to ontology concepts such that each term corresponds to a single concept which is its value, and values of terms are then ranked according to significance for the document.
