Functionality-Based Service Matchmaking for Service-Oriented Architecture

Service matchmaking is a basic feature of service-oriented architecture (SOA). In this paper, a semantic-based flexible service matchmaking approach is presented to efficiently identifying functionality-compatible services. This approach utilizes SAW-OWL-S to specify the service advertisements and service discovery requests. The functionality-compatibility of a service to a request is defined on their parameters and conditions. This approach uses functionality filtering to prune out incompatible services, and then select services based on the aggregated similarities of input/output parameters, precondition/result situations and other service attributes. Experimental results are given to illustrate that this approach can efficiently generate precise service matchmaking results
