Expert systems (or ES) consist of a number of parts, including a knowledge bank: in which all compiled information from expert is stored in an order and sequence. An inference engine: where information from the knowledge bank is extracted that relates to the problem at hand and is compiled together to produce an inference for the problem. Finally a knowledge refinement sector, where the ES tries to relate the problem one previously dealt with and stores new successful inferences. These are the main parts of an expert system. Others are displayed below in the following diagram: Development environment Consultation Environment Expert User Knowledge User Engineer Interface Knowledge Recommended Reasons Base Action Inference Knowledge engine Refinement How are Expert systems are made/ how do they work? As you can see, the diagram is split up into two "˜Environments'. The development environment and the Consultation environment. The Development side shows the...
