Dynamic service discovery through meta-interactions with service providers

Abstract:

Dynamic discovery based on semantic description of services is an essential aspect of the Semantic Web services integration process. Since not all data required for service discovery can always be included in service descriptions, some data needs to be obtained during run-time. In this paper we define a model for service interface allowing required data to be fetched from the service provider during discovery process. We also provide a specification of such interface for WSMO and demonstrate the model on a case scenario from the SWS Challenge implemented using WSMX - a middleware platform built specifically to enact semantic service oriented architectures. © Springer-Verlag Berlin Heidelberg 2007.
