Abstract: |
Web Services promise a new level of functionality on top of the current Web.
However, current Web Service technologies only provide syntactical descriptions
of Web Services and, therefore, they are not amenable to automation. The
efforts of WSMO aim at describing Web Services and their related aspects with
well-defined, formal semantics, thus providing a basis for the automatization of
various tasks in the Web Service usage process.
During the exchange with NUIG, which has taken place from July 22nd to
September 30th 2004, we have focused on the exploitation of semantic descriptions
of Web Services and user goals to automatically discover i.e. locate Web
Services that can fulfill a given goal. We have investigated a logical framework
which, based on the WSMO conceptual model, provides such functionality. In
addition, we have further investigated the distinction of capabilities and constraints
in the Web Service context and their role in WSMO.
