Abstract

In real life, as opposed to virtual, most information comes in the form of imprecise or incomplete values. XML technology has made great progress in the field of storage and data transfer. We developed XML extension which combines indefiniteness in the values of XML and indefiniteness in the structure of XML into a single fuzzy XML extension. Furthermore, this paper expands XQuery syntax with fuzzy values and includes priorities and thresholds in fuzzy XQuery extension using GPFCSP for the first time. Unlike other papers that focus on setting up theories and defining syntax, in this paper, special attention is turned to their practical use. A tool for working with XML, XSD and DTD documents and prioritized fuzzy XQuery extension queries has been developed. One of the advantages of this tool is defining arbitrary membership functions. The developed tool enables defined fuzzy XML extension and their performance to be tested in practice.
