Environs-an expert system: application to the impact of environmental pollution on the health of industrial workers and general public

An interactive system called Environs which enables experts gradually to construct a knowledge base is described. This rule-based expert system makes it possible for an expert to convey his expertise to the system without the intervention of a computer specialist. This knowledge-based production rule system is constructed to reduce the superfluity of rules and eliminate inconsistency, thereby securing maximum compatibility of the rules entered by the expert. The expert system is rule-interpreted with an optimized dialogue in pseudonatural language using the already-known facts. The system is tested on the impact of environmental pollution on the health of industrial workers and the general public. The application part is designed to detect a pollutant and its source or origin, and to help choose necessary steps in environmental pollution management
