Ontology-driven information integration for operational decision support

Abstract

The paper presents an approach to decision making in the dynamic environment. The approach is aimed at modeling and solving the decision maker's problem. The problem is modeled by abstract and operational contexts integrating relevant information and domain knowledge. Domain knowledge is represented by ontologies. Ontology management operations are used for creation of ontology-based contexts or for integration of knowledge relevant to the problem into context. Context management techniques are incorporated into organization of relevant information in the contexts. Object-oriented constraint networks serve as a mechanism for problem definition and solving. The approach is implemented as an adaptive service for humanitarian logistics support.
