introduction: an article with a clear message can transfer research knowledge better. however, this is the case when the message suits the type of  study methodology (research design) and its results. the objective of  this study was to assess the presence of  message articles and the type of  study methodologies. methods: articles published between 2001 and 2006, on maternal care, diabetes, an...

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...

Knowledge management is one of the critical issues for the improvement of enterprise performances. Different methods exist for extracting and formalizing knowledge in order to create knowledge-based applications. Most of integrated design and manufacturing technological processes are more or less based on knowledge that has been translated into models and then into Knowledge-Based Computer-Aide...

Argumentation concepts have been applied to numerous knowledge engineering endeavours in recent years. For example, a variety of logics have been developed to represent argumentation in the context of a dialectical situation such as a dialogue. In contrast to the dialectical approach, argumentation has also been used to structure knowledge. This can be seen as a non-dialectical approach. The To...

CAMES (computer-aided mechanical expert system) is a tool for automatically designing material-handling equipment used in pulp and paper mills. Operational since 1988, it has designed over 700 machines in a total of 5 classes and, consequently, has influenced our principles for deploying all knowledge-based systems. Because it is being extended to other machines within our group of companies, i...

This paper presents the TASK framework which is intended to cover the life cycle of a Knowledge-Based System. TASK provides (i) a conceptual language which enable an informal specification at the knowledge level, (ii) a formal language TFL which permits an unambiguous specification and (iii) an operational shell TASK+ which allows an efficient execution even for bad structured problems. This pa...

In the current economy, individual firms cannot possess all the knowledge that is necessary to compete. Hence, networking relationships become an important way through which firms can develop their potential by accessing to resources of other players. However, the networking strategies that companies implement can vary depending on the nature of their competitive conditions and on their specifi...

This paper will introduce, compare and contrast two prototype knowledge systems as it presents a more general framework for thinking about how community of practice and organizational perspectives to knowledge management might be integrated. The first prototype is called the Knowledge Nebula Crystallizer (KNC). The KNC is a demonstration of concept developed at the University of Tokyo. It is us...
