A discussion of knowledge and KnowledgeBased design as related to the design of aircraft is presented. The paper discusses the perceived problem with existing design studies and introduces the concepts of design and knowledge for a KnowledgeBased design system. A review of several Knowledge-Based design activities is provided. A Virtual Reality, Knowledge-Based system is proposed and reviewed. ...

When people engage with information, they are often in social groups. This applies, for example, in the case of museum visits, where people typically attend the museum and view the exhibits in small groups. This paper describes a proposed system GM, Group Modeller, which will create group models from a set of individual user models. We discuss the approaches and challenges in terms of common su...

Representing domain knowledge is crucial for any task. There has been a wide range of techniques developed to represent this knowledge, from older logic based approaches to the more recent deep learning based techniques (i.e. embeddings). In this paper, we discuss some of these methods, focusing on the representational expressiveness tradeoffs that are often made. In particular, we focus on the...

Automatic reasoning is applied to building design problems with a large number of standardized conditions, such as normal housing. Industrialized home building can provide quick-to-build low-cost dwellings, but these buildings often are not as appropriate for the local climate, building site or to the occupant needs as tailor-made homes. In this article we present a knowledge-based system (KBS)...

This paper describes a generic, knowledge-based mechanism used to make selections between a xed set of alternatives. The mechanism, termed sponsor-selector has been used as a control mechanism in a number of diierent knowledge-based systems including design, planning and problem-solver integration applications. We will discuss the general applicability of the sponsor-selector mechanism and desc...

The experience of experts relies on the process of decision-making jointly with the progressive elaboration of a context-specific model. However, context modeling generally stays implicit because only the result of the decisionmaking process matters. Modeling context within a decision-making process supposes a uniform representation of knowledge, reasoning and contexts. In the Contextual-Graphs...

Developing and maintaining large sofhvare systems is notoriously dimcult and expensive. One source of dificulty is that such projects involve large amounts of disparate knowledge about the domain, the hardware platform, the existing sofhvare architecture, the technical personnel and resources, etc. A critical problem is that a great deal of relevant knowledge is ‘yolklore”: it is not documented...

Self-medication, defined as the act to treat oneself with or without drugs, is a common practice in industrial countries. A study of available computerized solutions in this field highlights that this issue has not been considered with enough attention, although they provide valuable services to both patients and health care organizations. This paper presents XIMSA, a self-medication knowledge-...

This paper discusses the application of a previously reported theory of explanation rhetoric (Maybury, 1988b) to the task of explaining constraint violations in a hybrid rule/frame based system for resource allocation (Dawson et al, 1987). This research illustrates how discourse strategies of explanation, textual connectives, and additional justification knowledge can be applied to enhance the ...
