OWL and RDF/RDFS are ontological languages developed by the World Wide Web Consortium (W3), which have become a de facto standard for the, ontological descriptions in various domains. The evolution of these standards was influenced by the numerous advances in the research of knowledge representation and reasoning. Although support for reasoning and standardized representation is the key benefit, of these technologies, there is a lack of existing test, frameworks, which would be capable of addressing many crucial aspects of the Semantic Web applications. In this paper we propose a methodology for automated testing of OWL reasoners based on the real-world ontologies. This specification covers both terminological and assertional reasoning as well as checking of the correctness of the answers. An open-source implementation of such framework is described and a study of initial result is provided. The tests cover an extensive set of reasoners and ontologies and provide a state-of-the-art insight, into the field of OWL reasoning.

In this paper we present design and development of a knowledge framework for grid and web service-based workflow composition and execution. We highlight the corresponding architecture and the process of service annotation, discovery and composition in the project K-WfGrid [5]. We describe in detail the challenges of a flood-forecasting application and corresponding design and development of the service oriented model, which is based on the well known Web Service Resource Framework (WSRF). Semantic descriptions of the WSRF services are presented as well as the architecture, which exploits semantics in discovery and composition of service workflows. Further, we demonstrate how experience management solutions can aid the process of collaborative service discovery and composition. The whole K-Wf Grid system provides a unique approach in Semantic Grids by combining the advances of semantic web services and grid architectures.

Web Service Resource Framework (WSRF) is a recent effort of the grid community to facilitate modeling of the stateful services. Semantic Web Services (SWS) initiative is proposing a standard called OWL-S, to help the intelligent service provisioning i.e. automated discovery, composition and invocation of the services. In this paper we provide an overview of both frameworks and analyse their complementary features. We will also describe the OWL-S extensions necessary to cover the services introduced by the WSRF standard. Analysis of the requirements as well as description of the architecture is provided. A flood-forecasting application scenario is described, which have been used to evaluate the architecture.
