A module‐based conceptual framework for largescale expert systems

Increasing utilization of expert systems in organizations has ecessitated development of large‐scale expert systems that deal with complex problem domains requiring handling of large knowledge bases. Adapts the concepts and structures of open information systems to outline a conceptual framework for large‐scale expert system development called an open‐based expert system (OES) architecture. The framework proposes partitioning large‐scale expert systems development into smaller and autonomous expert system modules which communicate through a flexible interface. The expert system modules may be built small enough to achieve reliability, and the open structure of the architecture allows the modules to be incorporated into a larger information system. The OES architecture is implemented on vp‐expert shell, and a prototype is developed to demonstrate its working.
