Several technologies are emerging that provide new ways to capture, store, present and use knowledge. This book is the first to provide a comprehensive introduction to five of the most important of these technologies: Knowledge Engineering, Knowledge Based Engineering, Knowledge Webs, Ontologies and Semantic Webs. For each of these, answers are given to a number of key questions (What is it? Ho...

We will neglect so called quasi-problems of knowledge management, such as: group knowledge, organizational memory or organizational learning. The thing that is not a quasi-problem, but is not considered at all is the question: How much influence does the group/organization have on expert/decision makers learning? This question could be also examined using knowledge-based system, similarly as Ko...

In this paper we expose the theoretical background underlying our current research. This consists in the development of behaviour-based knowledge systems, for closing the gaps between behaviour-based and knowledge-based system s, and also between the understandings of the phenomena they model. We expose the requirem ents and stages for d eve loping behaviour-based knowledge system s and discuss...

We are developing a knowledge-based system capable of understanding oral task-:-oriented dialog$ ~nd proceS$ pseudo-natural sublang_uilges (with few ~Yt:Itactic restrictions) with large vocabularies (several thousand words) in a multi-speaker environment. Information Centers provide a wide range of potential applications, in as much as they deal with the general public, i.e. with a large number...

Product configuration systems are useful instruments of individualization in the field of mass customization. Recent studies have shown that the two factors Expertise and the Motivation to process information have a significant influence on the preference of configurators. In this paper we consider the influence of those two factors on the fit of two types of configuration systems: Parameter-ba...

This is the third report from the GridWeaver project. It describes how the LCFG and SmartFrog technologies have been combined, in prototype form, to create a largescale configuration system. First, we focus on the configuration aspects that must be modelled and examine how these are represented in the SmartFrog 2 language. Secondly, we discuss how the LCFG and SmartFrog systems have been combin...

This paper presents a complete framework for recognizing classes of machine-printed musical manuscripts. Our framework is designed around the decomposition of a manuscript into objects such as staves and bars which are processed with a knowledge base module that encodes rules in Prolog. Object decomposition focuses the recognition problem, and the rule base provides a powerful and exible way to...

PROTEAN is an evolving knowledge-based system that is intended to identify the three-dimensional conformations of proteins in solution. Using a variety of empirically derived constraints, PROTEAN must identify legal positions for each of a protein’s constituent structures (e.g., atoms, amino acids, helices) in threedimensional space. In fact, because protein-structure analysis is an underconstr...
