초록 ▼

An expert system includes a knowledge base manager which is fact-based, as opposed to rule-based; i.e., a semantic network with tangled hierarchies. The system includes an inference engine which is capable of providing solutions to indeterminate problems with a high degree of confidence. “Entities”(e.g., propositions, fact and ideas) are understood in eight different ways depending on the context of entity relationships. Each such relationship may be characterized anywhere along a spectrum from strong to weak. The knowledge base is designed so that entities and relationships are easily modified. The analysis performed may be at any of various levels of detail. The system can accept data as keyed input as well as from independently executed programs. Results developed by the inference engine are presented in various levels of detail in terms of relative degree of agreement or divergence from anticipated conclusions and the inference engine\s degree of confidence in the results.

대표청구항 ▼

A method of inference processing in a fact-based expert system comprising the steps of: generating a knowledge base by inputting and linking conceptual entities to create a network; assigning a qualitative value to relationships between entities; processing said knowledge base to solve a problem within a domain defined by said network by traversing said network following all linkages forward and backward; adjusting and accumulating said qualitative values for each entity processed; and generating a result and confidence measure thereof based on the assigned relationship values.
