同類網(wǎng)站查詢接口的集成系統(tǒng)設(shè)計(jì)與實(shí)現(xiàn)

摘 要:隨著Internet與網(wǎng)絡(luò)技術(shù)的飛速發(fā)展，網(wǎng)上的信息以海量方式增長(zhǎng)，然而我們卻不能快速而準(zhǔn)確獲取有效的信息。海量信息只能通過(guò)查詢接口訪問(wèn)獲得，為了能夠同時(shí)訪問(wèn)同一領(lǐng)域多個(gè)Web數(shù)據(jù)庫(kù)，需要對(duì)多個(gè)Web數(shù)據(jù)庫(kù)的查詢接口進(jìn)行集成．通過(guò)實(shí)驗(yàn)分析，基于查詢條件的深網(wǎng)查詢接口集成方法不僅簡(jiǎn)化了模式匹配的復(fù)雜過(guò)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．研究深度網(wǎng)的最終目的是為獲取隱藏于Web應(yīng)用之后的網(wǎng)絡(luò)數(shù)據(jù)庫(kù)中的數(shù)據(jù)，通過(guò)查詢接口在線訪問(wèn)后臺(tái)數(shù)據(jù)庫(kù)，這改變對(duì)傳統(tǒng)的基于搜索引擎的查詢和獲取信息的方式帶來(lái)了巨大的挑戰(zhàn)。傳統(tǒng)的搜索引擎只能進(jìn)行靜態(tài)頁(yè)面的搜索，現(xiàn)有的接口集成方法主要集成各個(gè)網(wǎng)站提供的高級(jí)搜索接口，這樣建立的集成接口由于包含過(guò)多的屬性，面在一些屬性上可代用戶選擇的候選值更是繁雜，不便用戶使用，于是設(shè)計(jì)了基于查詢條件的集成接口，避免了瀏覽復(fù)雜的查詢接口。

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.
