Modeling fuzzy data with XML: A survey

Uncertain information extensively exists in data and knowledge intensive applications, where fuzzy data play an import role in nature. Fuzzy set theory has been extensively applied to extend various database models and resulted in numerous contributions. This paper concentrates on a crucial issue in fuzzy data management: fuzzy data modeling in XML. An up-to-date overview of the current state of the art in fuzzy XML data modeling is provided in the paper. The paper serves as identifying possible research opportunities in the area of fuzzy XML data management in addition to providing a generic overview of the approaches proposed to modeling fuzzy XML data.
