Abstract. The SUPER project presents a novel approach to BPM by using Semantic Web and Semantic Web Services. Existing processes can be augmented with semantic annotations, so that formal reasoning techniques can be applied for discovery, composition, mediation and execution of business processes. This paper introduces a modelling environment that supports the SUPER approach to Semantic BPM. 1

Abstract. The two fundamental aims of managing educational resources are to enable resources to be reusable and interoperable and to enable Web-scale sharing of resources across learning communities. Currently, a variety of approaches have been proposed to expose and manage educational resources and their metadata on the Web. These are usually based on heterogeneous metadata standards and schemas, such as IEEE LOM or ADL SCORM, and diverse repository interfaces such as OAI-PMH or SQI. Also, there is still a lack of usage of controlled vocabularies and available data sets that could replace the widespread use of unstructured text for describing resources. On the other hand, the Linked Data approach has proven that it offers a set of successful principles that have the potential to alleviate the aforementioned issues. In this paper, we introduce an architecture and prototype which is fundamentally based on (a) Linked Data principles and (b) Service-orientation to resolve the integration issues for sharing educational resources.

Abstract. We present a goal-based approach for visualizing and browsing the search space of available Web services. A goal describes an objective that a client wants to solve by using Web services, abstracting from the technical details. Our visualization technique is based on a graph structure that organizes goal templates – i.e. generic and reusable objective descriptions – with respect to their semantic similarity, and keeps the relevant knowledge on the available Web services for solving them. This graph is generated automatically from the results of semantically enabled Web service discovery. In contrast to existing tools that categorize the available Web services on the basis of certain description elements, our tool allows clients to browse available Web services on the level of problems that can be solved by them and therewith to better understand the structure as well as the available resources in a domain. This paper explains the theoretic foundations of the approach and presents the prototypical implementation within the Web Service

Abstract. Many recent works aim at developing methods and tools for the processing of semantic Web services. In order to be properly tested, these tools must be applied to an appropriate benchmark, taking the form of a collection of semantic WS descriptions. However, all of the existing publicly available collections are limited by their size or their realism (use of randomly generated or resampled descriptions). Larger and realistic syntactic (WSDL) collections exist, but their semantic annotation requires a certain level of automation, due to the number of operations to be processed. In this article, we propose a fully automatic method to semantically annotate such large WS collections. Our approach is multimodal, in the sense it takes advantage of the latent semantics present not only in the parameter names, but also in the type names and structures. Concept-to-word association is performed by using Sigma, a mapping of WordNet to the SUMO ontology. After having described in details our annotation method, we apply it to the larger collection of real-world syntactic WS descriptions we could find, and assess its efficiency.

Abstract. One of the crucial reasons for adding semantic descriptions to Web services is to enable intelligent discovery, removing the need for a human to manually search and browse textual descriptions in repositories of services, like UDDI or ebXML. The Web Service Modeling Ontology (WSMO) provides a conceptual model within which the function of a Web service can be described in terms of formalized pre- and postconditions over the information space and assumptions and effects related to the real world; however WSMO is very flexible in the way in which the Semantic Web Service developer can use these elements to describe the functionality of a service. Thus a number of approaches for effectively describing the offered function of a Web service and the requirements of users, along with methods to compare them have surfaced in the last number of years, leaving developers unsure of which approach to use and if it is possible to combine them. In this paper we introduce a framework within which these different approaches can be combined and present some new tools that can be used with this framework by the Semantic Web Service developer. 1

Abstract: In this paper we will provide an overview of the Business Process Abstract Language (BPAL) Platform, which implements a Business Process (BP) modelling and reasoning environment where the procedural knowledge of a BP can be enriched through ontology-based annotations. The BPAL Platform provides a graphical user interface to ease the definition of a Business Process Knowledge Base that collects the various facets of process knowledge. It also provides a reasoner implementing services for the enactment, verification, retrieval, and composition of processes in the knowledge base. After discussing the functionalities and the architecture of the tool, we report on an experimental evaluation of the whole system, whose results are encouraging and show the viability of the approach. 1.

In recent years service-‐orientation has increasingly been adopted as one of the main approaches for developing complex distributed systems out of reusable components called services. Realizing the potential benefits of this software engineering approach requires semi-‐automated and automated techniques and tools for searching or locating services, selecting the suitable ones, composing them into complex processes, resolving heterogeneity issues through process and data mediation, and reduce other tedious yet recurrent tasks with minimal manual effort. Just as semantics has brought significant benefits to search, integration and analysis of data, semantics is also seen as a key to achieving a greater level of automation to service orientation. This has lead to research and development, as well as standardization efforts on semantic Web services. Activities related to semantic Web services have involved developing conceptual models or ontologies, algorithms and engines that could support machines in semi-‐automatically or automatically discovering, selecting, composing,
