Knowledge sharing is an important variable in the knowledge management literature emphasizing the importance of social factors. Recent research has revealed that social-psychological and sociological factors are imperative to knowledge sharing. The theory of reasoned action (TRA) was designed to model how any specified behavior under volitional control is produced by beliefs, attitudes, and int...

The effective use of knowledge based systems technology to solve complex and real-time problems in embedded system environments requires that the performance of these systems be maximized for conventional processor architectures. This paper presents a technique for the complete compilat ion of knowledge bases directly into procedural code. The technique is based on determining what actions an i...

Search, retrieval, and management of multimedia contents are challenging tasks for users and researchers alike. We introduce a software-hardware system for the global management of the multimedia contents produced by Spanish Civil Courts. The ultimate goal is to obtain an automatic classification of images and segments of the audiovisual records that, coupled with textual semantics, allows an e...

We address the problem of improving the reliability of independence-based causal discovery algorithms that results from the execution of statistical independence tests on small data sets, which typically have low reliability. We model the problem as a knowledge base containing a set of independence facts that are related through Pearl’s well-known axioms. Statistical tests on finite data sets m...

This paper describes the OpenVCE system, which is an open-source environment that integrates Web 2.0 technology and a 3D virtual world space to support collaborative work, specifically in large-scale emergency response scenarios, where the system has been evaluated. The support is achieved through procedural knowledge that is available to the system. OpenVCE supports the distributed knowledge e...

The procedural steps for developing an expert system for designing signals at isolated intersections are described and the most important development issues for each step are discussed. The steps include problem analysis and definition, preliminary prototype specification, knowledge acquisition strategy development, prototype development plan, knowledge extraction, knowledge representation, too...

People regularly need to cope with new challenging situations that cannot be mastered by only applying routine procedural skills and knowledge. Independently updating one’s set of skills and knowledge base in the context of technologically rich environments is essential to meet the changing lifeand workplace requirements. This paper proposes the creation and maintenance of landscapes of network...

The aim of this paper is to contribute to the construction of a systematic theoretical base for educational multimedia design. The paper delineates different layers of explanation. It then argues for the interactional layer as the most appropriate for multimedia learning environment design. It proposes 'context' as the central construct at this layer. The relationships between multimedia contex...

This paper explores VLSI synthesis and the role that traditional AI methods can play in solving this problem. VLSI synthesis is hard because interactions among decisions at different levels of abstraction make design choices difficult to identify and evaluate. Our knowledge engineering strategy tackles this problem by organizing knowledge to encourage reasoning about the design through multiple...
