How to make it faster and at lower cost? B2B integration with semantic web services

Web services and service oriented architectures present a new approach to application integration. While it is reasonable inside an enterprise, it has certain deficiencies when applied in a B2B environment. This deficiencies apply to the discovery, invocation and composition phases, which require considerable manual effort. In the paper, we show on example of a mortgage simulator how these deficiencies can be overcome by applying-semantic web services. The application is compatible with the Web Services Modelling Ontology and makes use of an execution environment automating the processes of discovery, composition and invocation of semantic web services, enabling faster and cheaper B2B application integration

IRS-III: A Broker for Semantic Web Services based Applications

In this paper we describe IRS-III which takes a semantic broker based approach to creating applications from Semantic Web Services by mediating between a service requester and one or more service providers. Business organisations can view Semantic Web Services as the basic mechanisms for integrating data and processes across applications on the Web. This paper extends previous publications on IRS by providing an overall description of our framework from the point of view of application development. More specifically, we describe the IRS-III methodology for building applications using Semantic Web Services and illustrate our approach through a use case on e-government

Supporting orchestration of blended CSCL scenarios in distributed learning environments

El diseño y gestión en tiempo real de escenarios de aprendizaje colaborativo soportado por ordenador (en inglés, CSCL) es una tarea compleja y difícilmente realizable por profesores no expertos, que en los últimos años ha dado en denominarse "orquestación". La presente tesis doctoral profundiza en este concepto de orquestación, y de hecho la primera contribución de la tesis es un marco conceptual para caracterizar la orquestación, destinada a su uso por científicos en el campo del CSCL, validado mediante dos paneles de científicos del CSCL. La tesis también propone los "patrones atómicos" como herramientas conceptuales para que profesores no expertos realicen dicha orquestación, y que se han validado mediante cuatro talleres con profesores de educación primaria y superior. Finalmente, se propone GLUE!-PS, una infraestructura tecnológica para el despliegue y gestión en tiempo real de escenarios CSCL, validada a través de talleres y experiencias auténticas con profesorado universitario.Departamento de Teoría de la Señal y Comunicaciones e Ingeniería Telemática2012-11-2

The choreography model for IRS-III

This paper describes how we manage the interaction between different heterogeneous web services through choreographies within IRS-III. IRS-III is a framework and platform for developing WSMO based semantic web services. Our choreography framework is based on the KADS system-client co-operation model that represents communication through two dimensions: the message direction and which actor has the initiative. Our formalism is state based and is thus compliant with Abstract State Machine (ASM) model used within WSMO. In addition to describing our approach in this paper we provide a formal semantics for IRS Choreography and a full implementation which we illustrate through an example application
