摘要
为了准确推断用户的查询意图,提出一个XML关键词查询和排序的方法。该方法首先根据XML文档结构和语义,分别建立标签信息表和文本信息表表示文档的结构和数据,然后通过标签和文本两个指标确定查询关键词和目标节点的相似性得分,给出排序方法。同时给出该方法实现的算法,并通过实验验证了该方法的有效性。实验结果表明,该方法可以更准确地推断用户查询的目标节点。
In order to accurately conclude user＇s query intent,we proposed an XML keyword query and ranking method. First,according to the structure and semantics of XML document,the method sets up tag_info table and text_info table respectively to represent the document structure and data,then determines the score of similarity between querying keywords and target node by two indicators of label and text,and gives the sorting approach as well as the algorithm to implement the method. Finally,we verified the effectiveness of the method through experiment; experimental results showed that the proposed method could more accurately conclude the target node of users query.
