Syntactic service matchmaking based on the fuzzy semantics of ontology

Ontology is widely used to describe the semantics of web services. But the algorithms for matchmaking ontology are always so complicated that the high precision is always attained at the expense of efficiency. This paper proposes a method of matching up services on the basis of ontology´s fuzzy semantics to promote the precision and efficiency at the same time. A syntactical structure is designed specially to accelerate the matchmaking process by narrowing the scale of effective service descriptions. And the fuzziness is embodied by the weight in services descriptions and is utilized to enhance the precison.
