【摘要】：XML已成為當前主流的數(shù)據(jù)存儲方式,對其進行信息的提取尤為重要,主要方法有兩個:1)用XPath,XQuery等工具,可對信息比較精確的提取,但用戶需要知道其語法;2)對XML的關鍵字搜索(XKS),利用SLCA/ELCA等技術對結果進行剪枝,雖然可以很好地解決第一個問題,但可能誤刪結果。提出一種新的XKS方法,保留所有的查詢結果,以網(wǎng)頁的形式呈現(xiàn)給用戶,緩存結果,根據(jù)用戶對結果的反饋信息,利用RANK和排序機制對結果顯示順序做調(diào)整,達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.
