Similarity retrieval methodology of stamping parts with relevance feedback.
摘要
Abstract
In order to seek the satisfactory stamping parts cases,relevance feedback process and module are added into the case tetrieval system. The calculation formula of stamping parts cases similarity degree and relevance feedback iterative method are presented. The results are calculated in a dual-step between the new part and old ones,arc judged by the users to define its relativity,and are taken into the feedback operation by means of Ide-regular algorithm. This course can be repeatedly circled to approach to a rather satisfied case. Deviation information is adopted into the weight update algorithm, which can combine the users' search preference and the self-information firom cases. The results show that this feedback means has high effectiveness in the similarity retrieval system.关键词
