   同类网站查询接口的集成系统设计与实现

摘 要:随着Internet与网络技术的飞速发展，网上的信息以海量方式增长，然而我们却不能快速而准确获取有效的信息。海量信息只能通过查询接口访问获得，为了能够同时访问同一领域多个Web数据库，需要对多个Web数据库的查询接口进行集成．通过实验分析，基于查询条件的深网查询接口集成方法不仅简化了模式匹配的复杂过程，而且很大程度上提高了模式集成的精度．因此，此集成方法是高效可行的．研究深度网的最终目的是为获取隐藏于Web应用之后的网络数据库中的数据，通过查询接口在线访问后台数据库，这改变对传统的基于搜索引擎的查询和获取信息的方式带来了巨大的挑战。传统的搜索引擎只能进行静态页面的搜索，现有的接口集成方法主要集成各个网站提供的高级搜索接口，这样建立的集成接口由于包含过多的属性，面在一些属性上可代用户选择的候选值更是繁杂，不便用户使用，于是设计了基于查询条件的集成接口，避免了浏览复杂的查询接口。

Congener website query interface integration system design and implementation

Abstract:With the rapid development of Internet and network technology, the information on the net growth in vast amounts of way, but we can't get effective information for accurate and fast. Can only be acquired through query interface to access vast amounts of information, in order to be able to access to the same field at the same time multiple Web database, the need for multiple Web database query interface integration. Through the experimental analysis, based on the query conditions of deep Web query interface integration method not only simplifies the complex process of pattern matching, and largely enhances the precision of model integration. Therefore, based on the query conditions of deep Web query interface integration method is efficient and feasible. The ultimate goal of network research depth is for hidden in the Web application after the network data in the database, through online access to background database query interface, which changed the traditional way based on search engine query and access to information brings great challenge. Traditional search engines can only carry on the static page search, the existing interface integration approach mainly integrated each site offers advanced search interface, so that establish the integration of the interface due to contain too many attributes, face on some of the properties for the user's choice of candidate values is more complex, inconvenient to users, so the integration interface design based on the query conditions, avoiding the browse complex query interface.
