Delivering Semantic Web Services

Abstract

The growing infrastructure forWeb Services assumes a ”program- mer in the loop” that hardcodes the connections betweenWeb Services and directly programs Web Service composition. Emerging technology based on DAML-S and the Semantic Web allows Web Services to connect and transact automatically with minimal or no intervention from programmers. In this paper we discuss the problems related with autonomousWeb Services, and how DAML- S provides the information to solve them. Furthermore, we de- scribe the implementation of two demonstration systems that use such technology: the first system is a B2B application in which a business that assembles computers automatically finds partners providing parts and automatically transacts with them; the second describes an e-commerce application that helps a user to organize a trip to a meeting automatically interacting with differentWeb Ser- vices and the calendar of the user stored in MSOutlook. The results of these experiments show how Web Services can be deployed on the Web to interact and provide information dynamically; second, how the transaction can be carried on automatically with no programmer intervention.
