为了解决普通用户对XML数据的模糊查询问题,提出了一种基于领域知识的XML数据模糊查询方法.以模糊集理论为基础,首先介绍了XML数据模糊查询的构成形式;然后提出了将领域知识和模糊集的隶属函数相结合的方法实现XML数据的模糊查询条件转换,转换过程考虑了查询谓词的重要程度和用户偏好;最后按结果元素对模糊查询的满足程度对模糊查询结果进行排序.该方法无需改变传统的XML查询语言和XDBMS就能够实现模糊查询,从而提高了用户与系统之间的交互能力.实验结果表明,提出的模糊查询方法具有较高的查全率和准确率.
- Abstract:

To deal with the problem of XML fuzzy query for common users, this paper proposes a domain knowledgebased XML data fuzzy query approach. Based on fuzzy sets theory, this paper firstly introduces the form of XML fuzzy query. And then, an approach which leverages the domain knowledge and membership function of fuzzy set to realize the fuzzy query translation of XML data, is presented. The importance of querying predicates and user preferences are taken into consideration when the fuzzy query is translated. Finally, for the fuzzy query results, the elements of them are ranked according to their satisfaction degree to the original fuzzy query. This approach can realize the fuzzy query without modifying XML query language and the XDBMS, and thus it can help users to improve their interaction with the system. Results of experiments demonstrate that the fuzzy query approach proposed in this paper has high recall ratio and precision.
