Abstract: To evaluate organization knowledge in the base quantitatively and efficiently,aiming at the manufacturing process knowledge base for the aviation enterprise,the knowledge unit coverage was proposed to measure knowledge,and the method to compute knowledge unit coverage was also provided.The method was composed of three contents: knowledge unit represented by object and solution,continuous attributes discretized to determine the number of knowledge unit,and the distance between knowledge units analyzed for effective coverage.An application example was given to validate the applicability and effectiveness of the proposed approach.According to calculation results on knowledge coverage,it was easy to realize quantitative analysis of organizational knowledge and to reflect the knowledge constitution in the base.

Key words: knowledge representation, knowledge measurement, discretization, knowledge coverage
