Ontological Retrieval of Technical Documents on the Basis of an Intelligent Agent Model 38_11.pdf

An intelligent agents modeling for the formation of information requests to an electronic archive of technical documents is considered in this paper. The intelligent agent contains an ontological description of the designer profile, which is expressed as a fragment of the domain ontology. In fact, the intelligent agent has information about the preferences of the electronic archive user. This information has a conceptual representation and it dynamically changes depending on the changing needs of the user. The designer profile is periodically updated with the concepts of the subject area from Wikipedia, so the applied ontology is expanding automatically. Basing on the user’s profile the intelligent agent solves the problem of the information retrieval of technical documents more effectively. The information retrieval algorithm is based on an ontological model which considers the user's query and a technical document as a set of concepts. The objectives of the intelligent agent are a replenishment of the information about the user’s needs in the designer profile, a conversion of the user query to a conceptual view and finding of the text documents requested by an electronic archive user. In the research process the subsystems of an ontological searching and an automatic generation of a concept network for the ontology were developed. Computational experiments were performed with these subsystems, which prove the effectiveness of the implemented approaches.

Ontology-oriented Method for Retrieval of Design Documents 30_12.pdf

The article presents a new method for information retrieval of text design documents, based on domain ontology. The article considers a formalized presentation of the information retrieval method enabling the improvement of accuracy factor due to the use of external information on domain status. Unlike known methods, the analysis of text design documents is not used at the level of document terms but at the level of concepts (notions) presented in the ontology of design organization.

Design documents, information retrieval, ontology, terms, concepts.

Development of Instrument of Ontology Engineering in Intellectual Design Repository 28_7.pdf

The present article is a result of researches whose important part is associated with the building of ontology of application of a design repository and the environment of its development. The paper deals with a concept of ontology from the point of view of informatics, presents a detailed description of subject-oriented editor of ontology, developed to solve tasks of intellectual analy-sis of design documents.
