中文摘要：
采用相关反馈技术提高检索效率已成为工程图纸检索方面的重要研究内容之一。现有的相关检索模型需要人工的多次参与,针对这个不足,提出一个基于反馈日志的检索模型：首先对工程图纸检索中的反馈日志进行分析,找出工程图纸之间的潜在关联关系,建立关联规则库;然后将传统的基于关键字的检索和基于内容匹配的检索两种方法结合起来;最后结合相关算法建立检索模型。实验表明,该检索模型可以减少人工参与检索的次数,并保证有较高的查准率。
英文摘要：
Using the relevance feedback technology to improve the efficiency has become the one of important research contents in the engineering drawings retrieval.Relevant retrieval model need artificial repeatedly involve in.To this shortage,this paper put forward a model based on feedback log.Firstly,it analyzed the feedback log to find potential relationship among engineering drawings,and establish the rules database.Secondly,it combined the traditional Key words：retrieval and the content-based engineering drawing retrieval.At last,according to relevant algorithm,it set up a retrieval model.The experiment result indicates that the new model can reduce the number of artificial involved in,and have a higher accuracy.
