Among the most important expected benefits of a global service oriented architecture leveraging web service standards is an increased level of automation in the discovery, composition, verification, monitoring and recovery of services for the realization of complex processes. Most existing works addressing this issue are based on the Ontology Web Language for Services (OWL-S) and founded on description logic. Because the discovery and composition tasks are designed to be fully automatic, the solutions are limited to the realization of rather simple processes. To overcome this deficiency, this paper proposes an approach in which service capability descriptions are based on full first order predicate logic and enable an interactive discovery and composition of services for the realization of complex processes. The proposed approach is well suited when automatic service discovery does not constitute an absolute requirement and the discovery can be done interactively (semi-automatically) w...
