Knowledge acquisition system and method.

摘要

A knowledge acquisition system (10) and method for a knowledge-based system are disclosed. The system (10) includes a knowledge structuring unit (12) which breaks a problem up into individual modules. A module represents an input/output relationship associated with the application with a knowledge source for a particular task. Knowledge structuring also provides knowledge sources for each module. A knowledge aggregation unit (14) acquires test cases and knowledge components in an inter-leaved fashion by performing knowledge-based verification (20) to permit the module to solve test cases and to permit a knowledge engineer or expert to make appropriate corrections to the module. Individual modules are then interconnected by the module interconnection unit (22) and again the entire system is verified by knowledge-based verification unit (24). The system (10) permits the rapid acquisition of relatively large knowledge bases derived partially from data or from an expert and also permits a knowledge-based system to use different inference engines (Fig. 1). <IMAGE>
