Recently, there are increasing numbers of sensors that report data from our physical environment. A sensor network consists of a number of spatially distributed and communicating sensor resources. Sensor networks have provided us with facilities to collect information and track certain phenomena in the physical environment based on the region of interest. W3C(World Wide Web Consortium) semantic sensor network group supports to develop an ontology to describe sensors and sensor networks for use in sensor network and sensor web applications. This paper proposes a semantic system architecture based on service provider for data acquisition from heterogeneous sensing sources. And, we design a semantic data model of service provider based on context Ontology. This architecture can help to make a meaning information for deciding an environment situation and assisting efficiently to manage facilities.
