Ontology-driven information integration for operational decision support

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.
