8 Institut Software- und Systemtechnik Fraunhofer ISS T 8 Languagelanguage-neutral master, DB-based language mappings Top Level OntologiesLocation Model, Time Model, Content Model Service OntologyBased on OWL-S, influenced by SWSO,WSMO; extended Focus on service retrieval Classification by taxonomies (service type, product, subject), integrated with DFKI Restrictions by context, situation, QoS, language, modality,... COMPASS Application Ontology

9 Institut Software- und Systemtechnik Fraunhofer ISS T 9 Service Ontology Overview

10 Institut Software- und Systemtechnik Fraunhofer ISS T 10 Service Registration Web client for service registration based on service metadata Structured according to COMPASS service ontology Input widely selected from ontology entries

11 Institut Software- und Systemtechnik Fraunhofer ISS T 11 Content selection - automatic - manual Adaptation of presented content - automatic service parameter provision (e.g. URL customization) - automatic content transformation / translation Personalisation and Context-Awareness Support
