SOA Service Discovery Mechanism of Smart Home Based on Ontology
Moji Wei · Computer Engineering and Science · 2012
Service is the key layer of SOA.It provides a framework for the Web Service.Based on the framework,the smart home system can achieve cross-platform service access.However,most of the service description and communication provided by the SOA such as SOAP,UDDI and WSDL are lack of semantic information during the retrieval process,and they cannot effectively deal with polysemy,synonymy and other grammatical problems.Through introducing the ontology technology,smart family service domain ontologies are built.The semantic annotations of services,content and equipment are implemented respectively based on function concept ontology,content ontology and device ontology.The process of services discovery is divided into three phases:function retrieval,service filtering and parameter matching.It can provide semantic-based intelligent smart home services discovery.
