Abstract

In the process of Internet of Things service discovery, users usually express their needs with their own intentions, while service description is the description of service functions, so the mismatch between the two will affect the accuracy of service discovery. At the same time, the accuracy of service discovery decreases with the increasing of service types. In order to solve the above problems, this paper proposed a method of introducing intentional service ontology into the description of IoT services, and extended the service context and QoS in the intentional service ontology. The extended intentional service ontology was stored in OWL-S(ontology Web language for services) files, which could express service functions in an intentional way, enrich the semantics of IoT service description, and improve the accuracy of service discovery. Simulation results show that the proposed service description method and the corresponding service discovery algorithm can improve the accuracy of 6.7% compared with the traditional service discovery method.
