Deep Web信息资源的查询接口集成研究

Query Interfaces Integrating on Deep Web

Deep Web信息是隐藏在Web服务器中可搜索的数据库信息资源,其信息量远比表面web信息量大。将Deep Web信息查询的接口模式集成为统一的查询接口,将极大地提高web信息检索的查全率和查准率。讨论了查询模式集成问题的聚类分析方法,相对于直接对Deep Web数据源的进行集成,对查询模式加以集成的思路成本更低。

The Hidden Web databases contain much more searchable information than the Surface Web databases. If the query interfaces on the Deep Web are integrated, the recall and precision of web information retrieval will be highly improved. This paper discusses the clustering analysis for query schema integration problem. The query＇ interface schema integration method costs less, compared with the Deep Web data source integration.
