Abstract:

Web Services is the latest IT buzz targeted to solve complex business
problems.  Specifically, composition of web services has received
much interest to support business-to-business or enterprise
application integration.  On the one side, the business world
has developed a number of XML-based standards to formalize the
specification of Web services, their flow composition
and execution. This approach is primarily syntactical: Web service
interfaces are like remote procedure call and the interaction
protocols are manually written.  On the other side, the Semantic Web
community focuses on reasoning about web resources by explicitly
declaring their preconditions and effects with terms precisely defined
in ontologies. For the composition of web services, they draw on
the goal-oriented inferencing from planning. So far, both approaches
have been developed rather independently of each other.

In this talk, we will first introduce typical applications that
businesses are interested in and outline their characteristics.
We then compare existing web services composition approaches on
how they address issues of modeling, composing, executing, and
verifying web services. We finally discuss what makes the web service
composition so special and derive challenges for the relevant
research community - AI planning, control systems and workflows.
