Service brokerage is a central issue in multiagent systems. Existing approaches often address the brokering among agents in terms of cooperative problem solving. Our work, however, deals with brokering the services offered to users in a multi-agent system. The user should be able to choose the desired services and assign concrete tasks to the service-offering agents utilizing those services. To...

Open Object–Based Systems are emerging as the underlying foundation for the design of large scale distributed applications. As an integral component of the ISO/ITU–T Reference Model for Open Distributed Processing, service brokering may be applied at multiple layers of the software hierarchy, spanning Distributed Operating Systems, through Telecommunication service provision up to the Applicati...

XML message brokering systems support customization that modifies the structure and content of XML messages under dissemination. This allows customized content delivery and data and application integration. In this work we present an approach for modifying XML documents in the context of XML message brokering. In our approach we propose to store XML data in its native form in a BDB XML database...

BACKGROUND Public health is to a large extent determined by non-health-sector policies. One approach to address this apparent paradox is to establish healthy public policies. This requires policy makers in non-health sectors to become more aware of the health impacts of their policies, and more willing to adopt evidence-informed policy measures to improve health. We employed a knowledge broker ...

Problems such as resource and service discovery models, load balancing and scheduling, brokering are eminent in grid systems due to bottlenecks such as bandwidth and network traffic in the underlying communication infrastructures and their associated costs in fabricating a scalable and cost effect grid services infrastructure. The primary goals of this paper is to apply grid based coalition for...

Tertius iungens brokering that brings together people who might not otherwise meet is crucial for organizational effectiveness. But we know little about whether and why women men differ in their propensity to engage this brokering. Our paper focuses on the origins mitigation of gender differences bring together. In study 1, showed Totterdell et al. (2008) propensity-to-join-others scale used 2 ...

In this paper we present an approach for reusing agent-based reasoning capabilities by making them available for invocation as Web services. In this way, we provide the missing link between the highly interoperable Web services and the autonomicity and intelligence of agent-based systems, so that the latter can be seamlessly integrated into the knowledge-rich Semantic Web environment without be...
