Web Service Discovery and Execution Using a Dialog-Based Approach

摘要

Several Semantic Web techniques applied in Service-oriented architectures enable explicit representation and reasoning on service operations. Those techniques applied to the automatic discovery, selection and execution of services are promising but still too complex to allow a large-scale adoption. Consequently, the most widespread approach for upgrading existing services to a semantic level is the usage of traditional software engineering practices, resulting in complex and non-intuitive interfaces in some cases. We propose an approach to leverage the service discovery, selection and execution processes for Web services without semantic annotations, using only the WSDL descriptor as a source. In order to do so, we first identify candidates based on linguistic cues extracted from the Web service descriptor. The generated proof-of-concept allows users to select and execute service operations through a personal assistant using restricted requests in natural language.
