Composing and Deploying Distributed Applications Using a Semantic Service Discovery Mechanism
نویسندگان
چکیده
We present semantic approach to discovering, composing and deploying distributed service-based applications. This approach allows users to advertise services on the network in agent form as well as compose meta-agents from existing agents. Agent advertisement is done through a rich RDF representation, enabling a semantic agent discovery layer that sits on top of traditional middleware. We present our prototype system that has been implemented in Java using Jini as the middleware. One hundred multimedia agents providing imagery, geospatial, video, and textual processing are currently implemented in the prototype system. We compare our service discovery mechanism to Jini and discuss results.

متن کاملTowards a semantic- and context-based approach for composing web services
Despite the widespread adoption of web services, several obstacles still hinder their smooth automatic composition. First, techniques that exploit semantic information during web services discovery are still lagging behind despite multiple initiatives like OWL-S. Second, the context in which web services evolve is, to a certain extent, ignored. This prevents deploying adaptable web services. In...
