DERIVATION IN THE EXTENDED RDF MODEL WITH FUZZY LOGIC

Both associative networks and RDF model (here we consider especially its graph version) belong to formal systems of knowledge representation based on concept-oriented paradigm. To treat properties of both of them as common properties of the systems is therefore natural. The article shows a possibility to use universal and existential quantified statements introduced prior to associative networks also within fuzzy RDF graphic system and to define a RDF formal system with extended syntax, semantic and fuzzy logic that can use inference rules of associative networks. We then also show how we may use fuzzy logic in solving example, a logical puzzle is presented.
