Semantic Services

Semantic service descriptions in service oriented architectures extend interface definitions from purely syntactical signatures to containing semantic information. This approach allows to for example enable automation of service usage. In particular, semantics are used as a basis to simplify and define the discovery, choice, execution and composition of services. Service descriptions are semantically described using ontologies that connect information stored in knowledge bases, and using rules that describe preconditions and effects of services. The CC ACT works at the incorporation of semantic technologies in the JIAC framework and develops new approaches in the areas of service discovery and service composition.
