Semantic Web Services
• Areas: (1) Semantic Web, and (2) Service-Oriented Computing
• Underlying Idea: abstract from software -> services• Semantic descriptions of services
• search, integration, mediation – increase automation and flexibility in service discovery, selection, negotiation, composition, mediation, invocation, ...
• 4 types of Service Semantics
• Information, Functional, Non-Functional, Behavioral
• Service Lifecycle• Model, Deploy, Assemble, Manage

Service Lifecycle
Model
Gather Requirements & Design
– Standards Compliance (Web,
Business) – ontologized business
standards, building on web standards
– Tools for Ontology Engineering
and Service Engineering

Challenges
• Complexity of business standards (e.g. RosettaNet)• Change management and versioning support
• Creating Service Descriptions from underlying sources (i.e. „service learning“)• Existing service descriptions (e.g. WSDL, REST, ...)• Documentation
• Source Code...
