摘要 为通过一个统一的接口访问所有分布的Web数据源,获得质量优结构好的信息,设计实现了包括Deep Web查询接口模式抽取、应用整体模式匹配算法的Deep Web查询接口模式匹配以及包含包括属性选择,表单元素生成和元素值域生成工作的查询接口集成3部分在内的基于整体模式匹配Deep Web集成系统。将该系统在Deep Web图书搜索系统中实际应用,运行结果表明,该系统设计是可行和有效的。 To get the good quality and excellent structure information through a unified interface to access all of the distribution of web data sources, the deep web integration system containing query interface schema extraction, query interface schema matching using holistic schema matching algorithm and query interface integration which including attribute selection, form elements generation and element range generation is designed, and the system is implemented in deep web book searching system. The operational result indicates that the system design is practicable and valid.
