Context-Aware Decision Support in Dynamic Environments: Methodology and Case Study
Dynamic environments assume on-the-fly decision support based on available information and current situation development. The paper addresses the methodology of context-aware decision support in dynamic environments. Context is modeled as a “problem situation.” It specifies domain knowledge describing the situation and problems to be solved in this situation. The context is produced based on the knowledge extracted from an application ontology, which is formalized as an object-oriented constraint network. The paper proposes a set of technologies that can be used to implement the ideas behind the research. An application of these ideas is illustrated by an example of decision support for tourists travelling by car. In this example, the proposed system generates ad hoc travel plans and assists tourists in planning their attraction attending times depending on the context information about the current situation in the region and its foreseen development.
