A tool for building decision-support-oriented expert systems

The expert system (ES) tool DECISION-T was built to test the authors' ideas on what characteristics an ES should have and how to reflect them consistently within a system. Concepts such as decision-support-oriented expert systems (DSO-ESs), the interrupt inference process, global-blackboard-based distributed problem solving, knowledge-based modeling, and data extraction are introduced. Multiple knowledge representation methods and inference engines are offered and integrated. The most salient characteristics of DECISION-T are the following: (1) it provides a well-developed environment which supports building various domain DSO-ESs; (2) the ESs built by it can fully reflect the nature of applied domains (especially the event processing abilities); and (3) good supporting facilities are offered.<
