Service discovery is one of the key tasks in SOA, locating a particular or a series of services by matching a user query with service advertisement in service repository. It’s crucial to the automation and intelligence of service invocation, achieving better user-experience of QoS.

We develop an ontology based context model, and domain-analyst oriented context reasoning rules, which...
