 Services, i.e. network pervasive programs or devices, facilitate interoperation by exposing their interfaces to each other. Such service-oriented research includes:    (ET)

Whilst services deliver dynamic, personalised, and relevant applications though discovery, invocation and composition, a key remaining challenge is to support automated interoperability without necessitating human intervention. The inclusion and use of Semantic Web annotations promise to make Web-based information and services both accessible and understandable to agents and other applications. Emerging ontologies (e.g. DAML-S) are being used to construct semantically rich service descriptions. Techniques for planning, composing, editing, reasoning and analysing about these descriptions are being investigated, and deployed to resolve semantic interoperability between services within scalable, open environments.    (EY)

Key research challenges in the area of Web services, Grid services and Multi-Agent computing include the construction of ontologies for service description, ontologies of service types (i.e. describing classes of services), etc, as well as techniques that support the manipulation of service descriptions to automate service discovery, translation, composition, etc.    (EZ)

This proposed symposium aims to bring together researchers addressing many of these issues, and promote and foster a greater understanding of how the Semantic Web can assist Grid, Web Services and Multi Agent System research.    (F0)

Those interested in participating should send either 1-3 page extended abstract, or an 8-page paper to Terry Payne ( by the submission deadline. Electronic submissions (Postscript or PDF) in AAAI format preferred    (FM)

 Call for Participation and Papers:
 Knowledge Representation and Ontology
 for Autonomous Systems    (FW)
 A Symposium at the 2004 AAAI Spring Symposium
 March 22-24, 2004
 Stanford University    (FX)
 For an autonomous system to behave appropriately in an uncertain 
 environment, many researchers feel that the system must have an internal 
 representation (world model) of entities, events, and situations that it 
 perceives in the world. The term “autonomous systems’ in this context 
 refers to embodied intelligent systems that can operate for extended 
 periods of time without human supervision. A major challenge for these 
 systems is maintaining an accurate internal representation of pertinent 
 information about the environment.    (FY)
 A large body of work exists in various knowledge representation, 
 ontology, and data fusion areas, yet relatively little has been applied 
 to real-time world modeling in autonomous systems. This symposium’s 
 objective is to bring together colleagues in the autonomous systems, 
 knowledge representation, ontology, and data fusion communities to 
 explore leveraging existing knowledge technologies to benefit autonomous 
 systems. Some topics of interest include:    (FZ)
 The symposium will consist of formal paper presentations describing 
 current research or visionary approaches, as well as interdisciplinary 
 discussion sessions focusing on topics areas related to knowledge 
 technologies for autonomous systems. Those interested in participating 
 are invited to submit either a full paper (5000 words maximum) or a 1-2 
 page statement of interest outlining their relevant research activities 
 and how they would like to contribute to the symposium. Please submit 
 papers in PDF format to Craig Schlenoff ( no 
 later than October 3, 2003.    (GF)
