    • Data and Process Mediation Support for B2B Integration 

      Zaremba, Maciej; Herold, Maximilian; Zaharia, Raluca; Vitvar, Tomas (2008)
      In this paper we present how Semantic Web Service technology can be used to overcome process and data heterogeneity in a B2B integration scenario. While one partner uses standards like RosettaNet for product purchase and ...

    • Dynamic Service Discovery through Meta-Interactions with Service Providers 

      Vitvar, Tomas; Zaremba, Maciej; Moran, Matthew (Springer, 2007)
      Dynamic discovery based on semantic description of services is an essential aspect of the Semantic Web services integration process. Since not all data required for service discovery can always be included in service ...

    • Handling heterogeneity in RosettaNet messages 

      Haller, Armin; Kotinurmi, Paavo; Vitvar, Tomas; Oren, Eyal (2007)
      We present a semantic B2B gateway based on the WSMX se- mantic Service-Oriented Architecture to tackle heterogeneities in RosettaNet messages. We develop a rich RosettaNet ontology and use the axiomatised knowledge and ...

    • Innovative Solution to Service Discovery and Integration using WSMOLX 

      Zaremba, Maciej; Zaharia, Raluca; Vitvar, Tomas (Springer, 2008)
      WSMX is a Semantic Web services broker enabling dynamic discovery and agile B2B integration of enterprise services. Our framework enables on-demand service discovery encompassing frequently changing aspects like fine-grained ...

    • Semantic SOA to Promote Integration of Heterogeneous B2B Services 

      Vitvar, Tomas; Moran, Matthew; Zaremba, Maciej; Haller, Armin; Kotinurmi, Paavo (IEEE, 2007)
      Modeling the semantics of business services and their corresponding messages using ontologies enables flexible integration that is more adaptive to business-driven change. In this paper we demonstrate our approach building ...

    • Semantic Web Services enabled B2B Integration 

      Kotinurmi, Paavo; Vitvar, Tomas; Haller, Armin (2006)
      The use of Semantic Web Service (SWS) technologies have been suggested to enable more dynamic B2B integration of heterogeneous systems and partners. We present our approach to accomplish dynamic B2B integrations based on ...

    • SESA: Emerging Technology for Service-Centric Environments 

      Vitvar, Tomas; Zaremba, Michal; Zaremba, Maciej; Moran, Matthew; Fensel, Dieter (Institute of Electrical and Electronics Engineers, 2007)
      Service-oriented architectures - and particularly the Web service technologies that enable them, such as WSDL (Web Services Description Language) and SOAP - are widely acknowledged for their potential to revolutionize ...

    • Towards Constraint-Based Composition With Incomplete Service Descriptions 

      Moran, Matthew; Vitvar, Tomas; Zaremba, Maciej (IEEE, 2007)
      We apply our work on Web service discovery with initially incomplete information to the problem of service com- position. Rich semantic descriptions of Goals and Web ser- vices allow the unambiguous specification of ...

    • Towards Optimized Data Fetching for Service Discovery 

      Zaremba, Maciej; Vitvar, Tomas; Moran, Matthew (IEEE, 2007)
      The advent of Service Oriented Architecture makes services the most flexible, platform-independent choice for exposing and integrating business functionality across a network. However, the lack of service discovery mechanisms, ...

    • Towards Semantic Interoperability (In-depth comparison of two approaches to solving Semantic Web Service Challenge mediation tasks) 

      Zaremba, Maciej; Vitvar, Tomas; Moran, Matthew (2007)
      This paper overviews and compares the DERI and DEI-Cefriel approaches to the SWS-Challenge workshop mediation scenario in terms of the utilized underlying technologies and delivered solutions. In the mediation scenario one ...

    • WSMO-PA: Formal Specification of Public Administration Service Model on Semantic Web Service Ontology 

      Wang, Xia; Peristeras, Vassilios; Vitvar, Tomas; Mocan, Adrian (IEEE, 2007)
      In this paper we define a formal model for a Public Ad- ministration service on the basis of the Web Service Modeling Ontology (WSMO). For this purpose we employ the generic public service object model of the Governance ...

    • WSMX: A Semantic Service Oriented Middleware for B2B Integration 

      Kotinurmi, Paavo; Moran, Matthew; Vitvar, Tomas; Zaremba, Maciej (Springer, 2006)
      In this paper we present a B2B integration scenario building on the principles of Semantic Web services. For this scenario we show the benefits of semantic descriptions used within the integration process to enable ...

    • WSMX: a Solution for B2B Mediation and Discovery Scenarios (demo) 

      Zaremba, Maciej; Vitvar, Tomas (2008)
      We demonstrate Web Service Execution Environment (WSMX), a semantic middleware platform for runtime service discovery, mediation and execution, applied to SWS Challenge scenarios. We show the modelling principles as well ...
