Abstract: Among the open issues for the modelling and execution of the service-oriented processes, the paper approaches the request-service matchmaking. In order to optimise it, the paper proposes the correlation of the service, process and request semantics, and the dynamic discovery of the services depending on the requestor|s preferences and on the service advertised quality. The paper first gives the steps for the service, process and request definition based on the activity semantics (standing for their common semantic base). Then, it gives the steps for the verification of the semantic completeness and correctness of the services and requests and details the two complementary algorithms for the request-service matchmaking, based on functional semantics and on the service quality semantics.
