Our goal is to build knowledge acquisition tools that support users in modifying knowledge-based systems. These modiications may require several individual changes to various components of the knowledge base, which need to be carefully coordinated to prevent users from leaving the knowledge-based system in an unusable state. This paper describes an approach to building knowledge acquisition too...

Knowledge management facilitates the capture, storage, and dissemination of knowledge using information technology. Methods for managing knowledge have become an important issue in the past few decades, and the KM community has developed a wide range of technologies and applications for both academic research and practical applications. In this paper, we propose a knowledge engineering approach...

This paper describes the results ofthe use of a Group Support System (GSS) and two “hindcasting” scenario exercises. The GSS is used to implement the hindcasting, knowledge mapping, and knowledge representation techniques as disaster planning tools. This work improves our understanding of the knowledge engineering process in the areas of knowledge acquisition, validation, and representation whe...

Making comparative judgments of intangible stimuli or criteria (e.g. the degree of an environmental hazard or pollution factors) involves not only imprecise or inexact knowledge but also inconsistency in our own judgements. The improvement of knowledge elicitation by controlling the inconsistency of experts’ judgments is not only desirable but absolutely necessary. Due to space limitations, the...

Received: 22 September 2011 Revised: 2 July 2012 Accepted: 17 October 2012 Abstract Numerous studies highlight the advantages of accessing knowledge from outside the firm as a means of enhancing the firm’s innovation efforts. However, access to external knowledge is not without organisational problems, including rejection of external knowledge by firm members or difficulties in applying such kn...

A great part of the product knowledge in manufacturing enterprises is only available in the form of natural language documents. The know-how recorded in these documents is an essential resource for successful competition in the market. From the viewpoint of knowledge management, however, documents have a severe limitation: They do not capture the wealth of knowledge contained in these documents...

Introduction Knowledge elicitation consists of a set of techniques and methods that attempt to elicit the knowledge of a domain expert1, typically through some form of direct interaction with the expert. Knowledge elicitation is a sub-process of knowledge acquisition (which deals with the acquisition or capture of knowledge from any source), and knowledge acquisition is, in turn, a sub-process ...

Constructing a planner for a particular application is a diicult job, for which little concrete support is currently available. The literature on planning is overwhelming and there is no clear synthesis of the various planning methods which could be used by knowledge engineers. In this paper, we show how a general, knowledge-level framework for conceptually specifying knowledge-based systems, c...
