| Abstract: | To improve the utilization efficiency of CAPP knowledge,the requirement of CAPP knowledge integration and the heterogeneous type of CAPP knowledge are analyzed firstly.Then,a CAPP knowledge integration frame based on ontology is proposed and a CAPP knowledge integration method based on ontology is presented.After that,a knowledge query arithmetic based on ontology is given.Finally,an example is given to verify the method.Results show that the precision and recall of knowledge query are improved considerably. |
