基于演化版本的 Deep Web 查询接口维护方法
Deep Web search interface maintenance method based on evolution version
摘要
Abstract
In order to solve the problems existed in the traditional Deep Web information integration system that without con-sidering the dynamic feature of search interface,causing local interface and network interface query ability is not equal.There-fore,this paper proposed a Deep Web search interface maintenance method based on evolution version.In this method,con-structing the version models of local search interface was to express the incremental change of it,and to extract the active attrib-ute set.Next,generating the best query string with the set and probing query was to extract the change content and get the next version of local interface.Finally,it could realize the iterative maintenance of local search interface data source.The experi-mental results show that this method is able to decrease the impact caused by deep Web network changing,and keep the recall and precision of Deep Web search interface in a stable state.关键词
