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...

Context: Knowledge management technologies have been employed across software engineering activities for more than two decades. Knowledge-based approaches can be used to facilitate software architecting activities (e.g., architectural evaluation). However, there is no comprehensive understanding on how various knowledge-based approaches (e.g., knowledge reuse) are employed in software architect...

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...

Reasoning about multi-agents systems at the knowledge level allows us to abstract away from many concrete details of the systems we are considering. Fagin et al. introduced two notions to facilitate designing and reasoning about systems in terms of knowledge. The first notion is that of knowledge-basedprograms. Knowledge-based programs are defined as syntactic objects: programs with tests for k...
