AbstractOrganisations are turning to customer-centric electronic services, oriented to servicing customers' life-events. This development requires methods for automatically locating and synthesising individual services to compose complex ones that will service the customer's life-events, since manual composition, either at the customer or the organisation side, incurs functional, economic and technical problems. In this paper we present an active blackboard architecture, which automates the task of service composition based on the semantics of individual services and data dependencies between them. The blackboard incorporates registries, which facilitate service discovery and an execution engine that arranges for dynamic service composition and execution.
