Development of ontology for intelligent scientific internet resource decision-making support in weakly formalized domains

The paper presents the ontology of knowledge area "Decision-making support in weakly formalized domains". The questions connected with a context of intended use of the ontology are considered. This ontology is developed as conceptual base of an intelligent scientific Internet resource which contains the systematized information on this knowledge area, provides content-based access to the information, methods of its processing, and also to methods of the solution of typical tasks. The paper shows that the knowledge area described by the ontology is extension of the classical theory of decision making which focuses its researches substantially on the questions relating to forming, estimation and the choice of versions of the solution of problem situations, i.e. the final stages of decision making. In compliance with this fact the presented ontology describes along with concepts of the classical theory of decision making the methods and facilities obtained in allied branch of science which can be successfully applied in decision making process, including its initial stages. The ontology contains also the concepts allowing to describe the software tools and Internet resources created in the considered area as well as the activities performed in it.
