The Ninja project seeks to enable the broad innovation of robust, scalable, distributed Internet services, and to permit the emerging class of extremely heterogeneous devices to seamlessly access these services. Our architecture consists of four basic elements: bases, which are powerful workstation cluster environments with a software platform that simpli®es scalable service construction; units...

This paper presents a context-driven approach that aims at supporting semantic mediation between composed Web services. Despite the widespread adoption of Web services by the IT community, innovative solutions are needed in order to overcome the challenging issue that relates to the semantic disparity of exchanged data. Indeed, there is a lack of means for interpreting these data according to t...

Web services are software components that can be accessed over the Internet by other software components. Web service workflows are a set of web services that are executed in a structured way. This paper introduces a workflow composer agent, which is able to compose web service workflows, and more importantly, uses semantic descriptions of web services in finding and matching web services for a...

In a service-oriented environment services can be composed such that new value added services are created. The problem of service composition raises a number of specific issues like the openness of the environment and the large number of possible services. As currently such massive service deployments do not exist, the current techniques proposed for service composition are difficult to test an...

Business applications composed of heterogeneous distributed components or Web services need mediation to resolve data and process mismatches at runtime. This paper describes mediation in IRS-III, a framework and platform for developing WSMO-based Semantic Web Services. We present our approach to mediation within Semantic Web Services and highlight the role of WSMO mediator types when solving mi...

Web services are basic components constructing a flexible business process software. By composing multiple Web services, a complicated business process across organization and departments can be formed. This paper present a formal model of composable Web services: composed service process nets (CSPNs). Properties of Composable Web services are analyzed based on CSPNs. The relation between a CSP...

The Business Objects Enterprise XI suite are a comprehensive suite of business intelligence (BI) applications for gathering, storing, analyzing, and providing access to operational data to help users and automated systems make fact-driven business decisions. The BusinessObjects Enterprise XI suite is composed of a set of interconnected services and tools, each optimized for specific tasks and o...

This paper presents an approach that combines Ontologies, Semantic Web Services and Mobile Agents, for the Component-Based Software Development. The Ontologies are employed to improve the problem domain analysis, and to get software components with a semantic description, which may be reused in a wide variety of applications. The Semantic Web Services are used as software components distributed...
