Abstract:

A method named preference ontology denotation by decomposed attributes (PODDA) was put forward to apply preference description to the dynamic services composition. This method added semantics to the service-preference of the user and decomposed this preference into many sub preference set or attribute preference set. By abstracting sub preference set from the relations of the domain ontology’s concepts and services’ attribute preference set from the relations between the concepts, the building of the relevant ontology could better utilize the existing resource in domain ontology and express the user’s preference under multiple restrictions more profoundly. The test result of the simulation system showed that after the preference ontology based PODDA was applied the satisfaction of composition service has been greatly increased.

Key words: semantics, ontology, preference, services composition
