Recognising faces is now an attractive computer vision task. Methods used for machine parts; recognizing straight lines or circular arcs, and the use of detailed geometric models, are not directly relevant, yet with many human faces to recognize, it is worthwhile building a system solely for this task. The system described here uses a blackboard architecture and aims to obtain a set of measurem...

In the modern business environment, the capability of an enterprise to generate value from its business knowledge influences in an increasingly important way its competitiveness. Towards this direction, knowledge-based systems can be a very effective tool for enhancing the productivity of knowledge workers by providing them with advanced knowledge processing capabilities. In this paper we descr...

This work is part of an industrial project between the ALCAN Ltd group and CRIM, a research center. It was supported by a joint grant from ALCAN Ltd and NSERC, operation grant #CRDPJ 228746-99. Abstract. A software product is expected to fulfill some need and meet some acceptance standards that dictate the qualities it must have. This paper presents a reengineering work tending to increase to a...

Traditional methods of managing human capital, innovation, and learning within organizations, particularly law firms, have proven ineffective as they often fail to contribute to a firm’s success. Over the last few decades, the rise of a knowledge-based economy has precipitated the need for management of such intangible assets, as they often signify a company’s competitive advantage. This paper ...

An information system is a representation of a real or virtual system. We assume that the design of an information system starts with a set of ontological constructs that are then mapped to a set of grammatical constructs. Given this assumption then an ontology of knowledge is a necessary starting point for conceptual modeling in the design of knowledge-based systems. This paper proposes a thre...

The knowledge acquisition bottleneck impeding the development of expert systems is being alleviated by the development of computer-based knowledge acquisition tools. These work directly with experts to elicit knowledge, and structure it appropriately to operate as a decision support tool within an expert system. However, the elicitation of expert knowledge and its effective transfer to a useful...

The paper discusses a proposal of a formal description of ARD+ a conceptual design and hierarchical refinement method for knowledge-based systems. Formalization of method syntax is given, as well as description of its semantics. ARD+ is a rework of the classic ARD presented elsewhere, that provides a conceptual design for rule-based systems. ARD+ is based on the concept of gradual design where ...

Purpose – To provide the knowledge structure for an effective knowledge-based organization which integrates knowledge into organizational goals. Design/methodology/approach – The structure, function, and process of a viable organization were discussed which provided a basis to construct a knowledge management (KM) framework and demonstrate knowledge structure in a knowledge-based organization. ...

In this paper, we investigate the modern issues of knowledge management and their impact on our living environment including business practices and health issues. We describe our vision through a highly computerised framework that combines technologies from different disciplines such as knowledge-based systems, database systems and multimedia technologies to support various knowledge management...

How does someone react when he faces a critical situation in his life? In this paper we present an agent-based model for simulating people’s behaviors in those particular situations. Coping strategies are at the heart of our model and we use some strategies developed in the area of psychology. We show the first step of our implementation architecture. We are currently implementing our model by ...
