Choreography of web services based on natural language storybooks

摘要

Universally available services, which communicate in a standardized way, can provide a new generation of middleware. Harnessing the advantages of this promising middleware technology, however, means to be capable to understand and to handle its design language which emerges from standards like SOAP, WSDL, BPEL, etc. These languages are necessary for finding, composing and orchestrating web services. If at all, only IT experts are familiar with these languages.The key actors, the domain experts of business processes, however, are not IT experts, and thus do not become the main designers. WS-Talk is a research project that encourages the co-existence of Natural Language and Web service technology. It reinforces the role of domain experts in designing business processes without having to resort to their IT colleagues. In our approach business process experts write storybooks in their own language. Their instructions are matched with semantics that represent application logic that, in turn, supports the automatic composition of software components. The WS-Talk products currently support organizations in managing their own and individual information, i.e. to set up their own enterprise search engine.
