We describe the ingredients of an intelligent agent (a broker) for connguration and execution of knowledge systems for customer requests. The knowledge systems are conngured from reusable problem-solving methods that reside in digital libraries on the Internet. The approach followed amounts to solving two subproblems: (i) the conngura-tion problem which implies that we have to reason about prob...

AIM To identify approaches used by advanced practice nurses to promote evidence-based practice among clinical nurses. BACKGROUND Barriers encountered at individual and organizational levels hinder clinical nurses in their ability to deliver evidence-based practice. Advanced practice nurses are well placed to promote evidence-based practice through interactions with clinical nurses. However, l...

The importance of knowledge is increasing in our global and knowledge-based society. As a part of knowledge management, successful knowledge transfer can improve an organization’s competitive advantages and increase an organization’s valuable knowledge assets. However, knowledge transfer is complex and a lot of factors exist that affect successful knowledge transfer such as context, social netw...

Coordination in distributed environments, like Grids, involves selecting the most appropriate services, resources or compositions to carry out the planned activities. Such functionalities appear at various levels of the infrastructure and in various means forming a blurry domain, where it is hard to see how the participating components are related and what their relevant properties are. In this...

InfoSleuth is an agent-based system for information discovery and retrieval in a dynamic, open environment. Brokering in InfoSleuth is a match-making process, recommending agents that provide services to agents requesting services. This paper discusses InfoSleuth’s distributed multibroker design and implementation. InfoSleuth’s brokering function combines reasoning over both the syntax and sema...

In this paper we study the brokering and matchmaking problem, that is, how a requester’s requirements and preferences can be matched against a set of offerings collected by a broker. The proposed solution uses the Semantic Web standard of RDF to represent the offerings, and a deductive logical language for expressing the requirements and preferences. We motivate and explain the approach we prop...

BACKGROUND Evidence-informed policy-making (EIPM) is optimal when evidence-producers (researchers) and policy developers work collaboratively to ensure the production and use of the best available evidence. This paper examined participants' perceptions of knowledge-brokering strategies used in the TROPIC (Translational Research in Obesity Prevention in Communities) project to facilitate the use...
