Abstract:
Among the main benefits of service-oriented architectures is the reutilization of software components that may solve specific tasks for complex problems, requiring the composition of multiple Web services. Currently Internet is largely populated with Web services offered by different providers and published in various Web repositories. However, public available Web services still suffer from problems that have been widely discussed, such as the lack of functional semantics. This lack of semantics makes very difficult the automatic discovery and invocation of public Web services, even when the system integrator can obtain a copy of the WSDL file. This paper describes an ontological approach for discovering similarity relations between public Web services. The objective of this work is to extract relevant data that is coded into service operations descriptions, calculate similarity measures between them, represent the discovered similarities in an ontological form, and execute inference. Experimental results show that the overall process towards the automation of public Web services discovery based on ontology population and structural similarity measures is feasible and can be completely automated.
