Fuzzy Logic Programming for Implementing a Flexible XPath-based Query Language

FLOPER is the ''Fuzzy LOgic Programming Environment for Research'' designed in our research group for assisting the development of real-world applications where fuzzy logic might play an important role. This is the case of our recently proposed extension for the popular XPath query language in order to handle flexible queries which provide ranked answers, fuzzy variants of operators and, or and avg for XPath conditions, as well as two structural constraints, called down and deep, for which a certain degree of relevance can be associated.
