| 摘 要： | 在实际应用中数据经常存在不确定性和模糊性,因而对模糊XML数据的关键字查询处理成为一种非专业用户的需求.针对模糊XML数据的关键字查询方法进行研究,对模糊XML的关键字查询语义进行分析,提出一种新的模糊XML文档的编码方法 CDewey,该编码方法能够有效地对节点类型进行区分.在此基础上,提出关键字查询算法FIndex Loop,该算法能够准确求解输入关键字的SLCA结果及结果的可能性值,最后通过实验表明此查询方法的有效性.

| Abstract: | In the practical application，there often exists uncertainty and ambiguity in the data. Keyword query processing over fuzzy XML data becomes a requirement for non professional users. Aiming at making a research on the method of keyword querying over fuzzy XML data，the semantics of keyword querying over fuzzy XML was analyzed， and a new coding method CDewey for the fuzzy XML document was proposed. Types of nodes could be effectively distinguished by this coding method. On the bases， a keyword query algorithm FIndex Loop was proposed， this algorithm can get the SLCA results of keywords inputted and values of possibilities of the results accurately. Finally， experimental results showed the effectiveness of the query method. |
