知识服务中基于WKNN-MF与NRS的非完备案例知识匹配
Incomplete Case Knowledge Matching Based on WKNN-MF and NRS in Knowledge Service Process
摘要
Abstract
To improve the benefits of knowledge services and solve the problem of missing attribute values of incomplete case knowledge,a knowledge matching method based on WKNN-MF and NRS was de-signed.The WKNN algorithm was used to pre-populate the non-complete case knowledge set as the basis of MF calculation,and WKNN-MF was used to obtain the complete case knowledge set.On this basis,NRS simplification was performed to eliminate redundant attributes,and then similar cases were searched by the similarity of knowledge views to determine the knowledge matching results.Experimental results based on three different UCI datasets showed that the proposed method had a better filling effect on in-complete case knowledge sets compared with existing data-filling algorithms.关键词
