Template-Based Generation of Semantic Services
- 801 Downloads
There are many technologies for the automation of processes that deal with services; examples are service discovery and composition. Automation of these processes requires that the services are described semantically. However, semantically described services are currently not or only rarely available, which limits the applicability of discovery and composition approaches. The systematic support for creating new semantic services usable by automated technologies is an open problem.
We tackle this problem with a template based approach: Domain independent templates are instantiated with domain specific services and boolean expressions. This process yields both the description and the implementation of new services whose correctness directly follows from the correctness of the template. Besides the theory, we present a preliminary evaluation for service repositories in which 85% of the services were generated automatically in efficient time and explain why these are indeed useful.
