基于XML Schema的模糊数据建模方法

Fuzzy Data Modeling Based on XML Schema

为了满足现实Web应用中对不精确和不确定信息处理的需要,提出了一种基于XML Schema的模糊XML数据模型.利用该模糊XML数据模型,模糊信息在XML文档中能以自然的方式进行表示.在模糊集和可能性分布理论的基础上,分析了XML文档中模糊数据的多重粒度,给出了不同类型模糊数据的XML Schema表示方法.为模糊数据的Web发布与共享,以及实现基于Web的智能信息处理奠定了坚实的基础.

To meet the requirement for imprecise and uncertain information processing in the actual applications of the Web, a fuzzy XML data model is developed on the basis of the XML Schema. With the model used, the fuzzy information in XML documents can be represented naturally. Based on the fuzzy set and possibility distribution theory, the multiple granularities of data fuzziness in XML documents are identified so as to provide various types of XML Schema representations that address all types of fuzziness. The fuzzy XML data model will lay a firm foundation for fuzzy data releasing and intelligent processing on the Web.
