Semantic Service Registration and Retrieval for Smart Home

In order to solve the syntax problem of service retrieval based on keywords, we present an Ontology-based solution for service registration and retrieval in this paper. Firstly we analyze the semantics of home service from different facets, and extract relative concepts of service to construct three domain ontologies including function ontology, content ontology and device ontology. Then, a model based on these domain ontologies has been presented. Finally the process from registration to retrieval is given in detail.
