Modeling Utility Ontologies in Agentcities with a Collaborative Approach

paper presents experiences about the modeling and implementation of utility ontologies used within the Agentcities initiative. Utility ontologies include domain-independent concepts which most services developed within the project use. Ontology building was carried out collaboratively among very different partners from industry and academia. The application domain of the ontologies is an open, dynamic test-bed for agent deployment and they are explicitly designed to be shared by most services created within this environment. The ontologies are implemented in the DAML+OIL knowledge-representation language and a summary is given of the tools which currently let the user manage this language at a high level.
