Conceptual Design Methodology for Fuzzy XML Model
一种模糊XML模型的概念设计方法

XML has been the defacto standard of information representation and exchange over Web. In addition, imprecise and uncertain data are inherent in the real world. Although fuzzy information has been extensively investigated in the context of relational model, the classical relational database model and its fuzzy extension to date do not satisfy the need of modeling complex objects with imprecision and uncertainty on the Web. Based on possibility distributions, this paper concentrated on fuzzy information modeling in the fuzzy XML model and the fuzzy IFO model. In particular, the formal approach to mapping a fuzzy IFO model to a fuzzy DTD model was developed.
