AWeSOMe 2008 PC Co-chairs' Message

The Fourth International Workshop on Agents and Web Services Merging in Distributed Environments (AWeSOMe 2008) was held in conjunction with the OnTheMove Federated Conferences (OTM 2008) in Monterrey, Mexico, in November 2008. AWeSOMe is an interdisciplinary workshop focusing on research and applications combining Web services, ontologies and agents, leading to the development of an intelligent service Web. Web services are a rapidly expanding approach to building distributed software systems across networks such as the Internet. A Web service is an operation typically addressed via a URI, declaratively described using widely accepted standards, and accessed via platform-independent XML-based messages.
