FUKG

FUKG (FUzzy Knowledge Graphs) is a software prototype to solve flexible queries over knowledge graphs. Supported flexible queries are described using fuzzy sets to constrain the values of the numerical data properties. In particular, a flexible query is characterized by:

• A set of classes
• A set of n functional numerical data properties
• A list of n Fuzzy OWL 2 datatypes
• A list of n fuzzy hedges (none, very, few)
• An optional retrieval operator for the classes (and, or)
• An optional fusion operator (product, minimum, maximum, weighted mean, OWA)
• An optional maximum of results
