Abstract: The article presents a description of alleged approaches to the implementation of data processing subsystem on Internet portal. Main problems are connected with exponential growth in number of documents, lack of semantic indexing and unstructured nature of information. In proposed approach, user receives an effective intelligent means of finding electronic documents on the basis of semantic indexing, automatic classification and cataloging of documents with construction of semantic links between them and automatic summarization of documents with the use of knowledge. The proposal is to increase the effectiveness of working with electronic documents with the help of intelligent analysis, for which agent-based and ontological approaches are used. In accordance with the proposed approach, ontology is used to describe data semantics of the document and its structure. Ontology is a central concept in process of document analysis. Through the use of ontologies the required data can be obtained; we know where to find information and how it can be interpreted. Ontology Repository contains three levels of ontologies. At the first level there are ontologies describing objects which are used in a particular system and which take into account system features. At the second level there are objects described in terms of the first level that are invariant to the domain. Objects of the third level describe the most general concepts and axioms, by which the lower levels objects are described. The third and second levels can be divided into two parts: a description of structures and description of the documents themselves.

Keywords: ontology, agent, multi-agent systems, intelligent search, semantic indexing, document analysis, adaptive information systems, CASE-technology.
