Abstract
Semantic Web technology facilitates automatic processing of
information on the Web by making up for the inadequacy of resources
that are only human-readable. It also enables service discovery when
services are described with OWL, a markup language for the Web based
on Description Logic. Service searches and classifications are
achieved via Description Logic inference mechanisms. The
expressiveness of OWL, however, is restricted due to decidability
concerns. This is complemented by SWRL, a combination of subsets of
OWL and RuleML, which contributes the use of Horn-like rules in
conjunction with ontologies. It also provides extra inference
capabilities for the ontologies.
We consider a practical approach that exploits reasoning services on
ontologies and rules based on current Semantic Web standards, to
provide a framework for service composition. In this framework one
can build ontologies and rules for the application domain, and
utilizes the inference services to accomplish service composition.
We also present an application for this framework and
discuss some implementation issues.
