Web services are emerging as a major technology for deploying automated interactions between
distributed and heterogeneous applications. Various standards support this deployment including
WSDL, UDDI, and SOAP. These standards respectively support the definition of Web services,
their advertisement to potential users, and finally their binding for invocation purposes. In general,
composing Web services rather than accessing a single Web service is essential and provides
better benefits to users.
After the previous three editions of the Web Services Symposium (WSS) at Zayed University,
Dubai, U.A.E (www.zu.ac.ae/wss), the 2011 edition of the WSS will be organized in Hammamet,
Tunisia on April 20th and 21st by the Multimedia, and InfoRmation systems and Advanced
Computing Laboratory (Mir@cl), Sfax University, Tunisia. WSS’2011 aims to offer a forum for
scientists, engineers, and practitioners to present their latest research, results, ideas, developments,
and applications of Web services. It will feature keynote presentations, paper presentations, special
sessions and demonstrations.
Topics of interest include, but are not limited to:
Standards for Web services
Semantic Web services
Context-aware Web services
Composition approaches for Web services
Security of Web services
Software agents for Web services composition
Supporting SWS Deployment
Architectures for SWS Deployment
Applications of SWS to E-business and E-government
Supporting Enterprise Application Integration with SWS
SWS Conversational Protocols and Choreography
Ontologies and Languages for Service Description
Ontologies and Languages for Process Modeling
Foundations of Reasoning about Services and/or Processes
Composition of Semantic Web Services

INTENDED AUDIENCE
The intended audience includes researchers working on Web services, Grid services, and related
technologies; students interested in these topics; developers of commercial Web services standards
(such as those engaged in these activities at W3C and OASIS); and commercial software
developers who are investigating how to achieve greater flexibility and automation in the delivery
of Web services.
