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

Service Lifecycle Model Deploy Publish Service Descriptions – Publish and Search Services – Semantic Repositories Gather Requirements & Design – Standards Compliance (Web, Business) – ontologized business standards, building on web standards – Tools for Ontology Engineering, and Service Engineering

Service Lifecycle Model Deploy Assemble Gather Requirements & Design – Standards Compliance (Web, Business) – ontologized business standards, building on web standards – Tools for Ontology Engineering, and Service Engineering Publish Service Descriptions – Publish and Search Services – Semantic Repositories Integration and Mediation – Discovery, Selection, Contracting, Composition, Mediation

Service Lifecycle Model Deploy Assemble Execute & Manage Gather Requirements & Design – Standards Compliance (Web, Business) – ontologized business standards, building on web standards – Tools for Ontology Engineering, and Service Engineering Publish Service Descriptions – Publish and Search Services – Semantic Repositories Integration and Mediation – Discovery, Selection, Contracting, Composition, Mediation Execution, Management – Invocation, conversation, mediation, maintenance
