Approach to decision support Intelligent Systems development based on Ontologies

Lytvyn V., Oborska O., Vovnjanka R.

ECONTECHMOD : An International Quarterly Journal on Economics of Technology and Modelling Processes

2015

Vol. 4, No 4

29--35

This article describes approach to the decision support intelligent systems development based on ontologies as part of such systems knowledge bases. Such systems are classified in terms of their functioning based on ontologies. Mathematical functioning of decision support intelligent systems is developed, which is based on ontologies. The term adaptive ontology is introduced to denote that. The adaptive ontology model is defined as classic model development by adding weights of importance of concepts and relations, stored in ontology.

Design of intelligent decision support systems using ontological approach

Lytvyn V.

ECONTECHMOD : An International Quarterly Journal on Economics of Technology and Modelling Processes

2013

Vol. 2, No 1

31--37

Methods of developing and functioning of intelligent decision support systems based on precedents applying adaptive ontology that are part of intelligent agents are analyzed. Method of distance defi nition between precedens and current situation based on adaptive ontology is developed. Using mathematical tools of the dynamic programming for modelling of intelligent system functioning is considered. Simplifying the task model is proposed to weigh signs of ontology concepts. Examples of such problems for six processes concerning metal structures protection and maximizing their lifetime are presented.

Intelligent agent on the basis of adaptive ontologies

Lytvyn V., Medykovskyj M., Shakhovska N., Dosyn D.

Journal of Applied Computer Science

2012

Vol. 20, nr 2

71-77

The metrics for evaluation of the similarity of summaries of scientific papers using the ontology approach has been elaborated. With this purpose the concept of adaptive ontology has been used. The developed approach has been verified on practical cases.
