This paper analyzes the structure and proposed information system data processing algorithm for finding semantically similar documents.

Based on the results of the study determined the structure of the information processing systems, a feature which is based on the principles of functioning of subsystems aimed at improving search relevance partynentnosti and unstructured information, namely the subsystem dialog mode user interaction subsystem finding semantically similar documents and subsystems forming clusters associated air knitted important terms of the document.

The method and algorithm of finding semantically similar documents, a feature which is the ability to clarify the information needs of users and build a more precise search.

Keywords: information system, search engine, unstructured information.
