In order to help the knowledge engineer to extract and organize explanatory and cooperation knowledge when building an Explainable Knowledge Based System, we propose : 1) an extension of the KADS Conceptual model; 2) an explanatory knowledge extraction method which relies on KADS interpretation models.

Competence-based extensions of Knowledge Space Theory are suggested as a formal framework for implementing key features of personalised learning in technology-enhanced learning. The approach links learning objects and assessment problems to the relevant skills that are taught or required. Various ways to derive these skills from domain ontologies are discussed in detail. Moreover, it is shown t...

This paper challenges the relevance of knowledgebased management research by arguing that the majority of the literature emphasizes information and knowledge provision instead of their business usage. For this reason the related processes are considered valuable and eligible as such, which has led to overlapping nature of knowledge-based management disciplines. As a solution, this paper turns t...

The aim of this work is to present heuristic algorithms in order to determine possible inconsistences of a knowledge base system (KBS). These algorithms will be based on the measure of an associated probability to the set of P complex formulations (set of single logic propositions))3]. Results will be assessed and further remarks concerning the valuation of the KBS will be considered.

Deliberate exploitation of natural resources and excessive use of environmentally abhorrent materials have resulted in environmental disruptions threatening the life support systems. A human centric approach of development has already damaged nature to a large extent. This has attracted the attention of environmental specialists and policy makers. It has also led to discussions at various natio...

This introductory article reviews the main themes relating to the development of new knowledge-based economies. After placing their emergence in historical perspective and proposing a theoretical framework which distinguishes knowledge from information, the authors characterize the specific nature of such economies. They go on to deal with some of the major issues concerning the new skills and ...

scientific AIDS literature describing specific human immunodeficiency virus (HIV) drug resistances directly to the customized treatment strategy of a specific HIV patient. Rules in the CTSHIV knowledge base encode knowledge about sequence mutations in the HIV genome that have been found to result in drug resistance to the HIV virus. Rules are applied to the actual HIV sequences of the virus str...

During the development and the life-cycle of knowledge-based systems the requirements on the system and the knowledge in the system will change. One of the types of knowledge aaected by changing requirements is control-knowledge, which prescribes the ordering of problem-solving steps. Machine-learning can aid developers of knowledge-based systems in adapting their systems to changing requiremen...

global representation is able to incorporate all the relevant information for monitoring and supervising the manufacturing. In addition it should provide the operator interface with all the information required by the operator. Finally, such an object-based architecture will constitute an open representational system, which is able to represent additional information and knowledge when found us...
