【摘要】：XML已成為當(dāng)前主流的數(shù)據(jù)存儲(chǔ)方式,對(duì)其進(jìn)行信息的提取尤為重要,主要方法有兩個(gè):1)用XPath,XQuery等工具,可對(duì)信息比較精確的提取,但用戶需要知道其語(yǔ)法;2)對(duì)XML的關(guān)鍵字搜索(XKS),利用SLCA/ELCA等技術(shù)對(duì)結(jié)果進(jìn)行剪枝,雖然可以很好地解決第一個(gè)問(wèn)題,但可能誤刪結(jié)果。提出一種新的XKS方法,保留所有的查詢結(jié)果,以網(wǎng)頁(yè)的形式呈現(xiàn)給用戶,緩存結(jié)果,根據(jù)用戶對(duì)結(jié)果的反饋信息,利用RANK和排序機(jī)制對(duì)結(jié)果顯示順序做調(diào)整,達(dá)到查詢的精確度要求。
[Abstract]:XML has become the current mainstream data storage mode, it is particularly important to extract the information. There are two main methods: 1) using XPath,XQuery and other tools, it can extract the information more accurately, but users need to know its syntax; 2) using SLCA/ELCA and other techniques to prune the results of the keyword search (XKS), of XML, although the first problem can be solved well, the result may be deleted by mistake. A new XKS method is proposed, which preserves all the query results, presents the results to the user in the form of a web page, caches the results, and adjusts the display order of the results by RANK and sorting mechanism according to the feedback information of the users to the results. Meet the accuracy requirements of the query.
