Showing papers in "Knowledge Acquisition in 1993"


Journal ArticleDOI
TL;DR: This paper describes a mechanism for defining ontologies that are portable over representation systems, basing Ontolingua itself on an ontology of domain-independent, representational idioms.

12,962 citations



Journal ArticleDOI
TL;DR: Knowledge acquisition tools can be associated with knowledge-based application problems and problem-solving methods as mentioned in this paper, and a framework for analysing and comparing tools and techniques, and focusing the task of building knowledge based systems on the knowledge acquisition process.

233 citations


Journal ArticleDOI
TL;DR: Results suggest that this approach is capable of providing a naturalistic knowledge elicitation environment endorsed by users, an externalization of experts' intuitive knowledge in a form which is similar to their own mental representation and an integrated, large-scale knowledge set suitable for infusing knowledge into AI architectures and human-computer interface design.

61 citations


Journal ArticleDOI
TL;DR: It is argued that the informal, verbal way in which the building blocks are defined is the cause of this problem, and proposed to formalize them to make their semantics clear and to assess the consequences of various modeling decisions.

30 citations


Journal ArticleDOI
TL;DR: A proposal for a next generation knowledge modeling environment that extends term classification technology with refinement, constraints, patterns and events, actions and methods, in order to support the description of both domain and control specifications required by problem-solving models.

18 citations


Journal ArticleDOI
TL;DR: This decision model combines current brainstorming-oriented methods, structured text argumentation (using the gIBIS model), repertory grids, possibility tables (morphological charts) and influence diagrams from decision analysis, which addresses weaknesses in current group decision support systems.

17 citations


Journal ArticleDOI
TL;DR: The Active Glossary is an explicit mapping between the outcome of a workplace analysis and the design of a problem-solving approach, and assists the development team with exploiting the similarities for the purpose of reusing previously defined workplace descriptions and programming constructs for new situations.

16 citations


Journal ArticleDOI
TL;DR: This work presents a method for automatically generating a model-based KA tool for a given set of mechanisms, and advocates combining KA mechanisms, which acquire knowledge in the small, and a set of strategies that provide a global view of the KA activity.

14 citations


Journal ArticleDOI
TL;DR: This paper concludes with the setting out of a thoroughgoing anti-realist philosophy of mind which enables the generic task view to avoid many of these problems.

Journal ArticleDOI
TL;DR: Using first-order logic does complicate things, but it provides, as a reward, a powerful way of extracting and validating the acquired knowledge, especially when the field expert is unable to express his knowledge in a simple way.

Journal ArticleDOI
TL;DR: A general purpose knowledge management system that functions primarily as a knowledge engineer's rapid prototyper, or as a "spreadsheet for ideas"; one can experiment rapidly with relationships between concepts and obtain quick feedback on the desirability of changes and additions to a knowledge base.

Journal ArticleDOI
TL;DR: A task support system with a graphical interaction language for the acquisition and display of plan knowledge, where the intended users are domain experts and novices and where previous computer literacy is not required, and a cognitive model of the users' view of tasks is proposed.

Journal ArticleDOI
TL;DR: A prototype workbench which has been developed to provide an integrated approach to the application of the ID3 algorithm, an important representative of the inductive learning family is presented and the design rationale and the potential use of the system are justified.

Journal ArticleDOI
TL;DR: It is shown that conceptual models can be operationalized by continuous refinement, without the need for a separate manual and structure-transforming implementation phase, and can be the basis for a fruitful integration of both kinds of modeling in a spiral development cycle.

Journal ArticleDOI
TL;DR: Experimentally self-elicited decision analyst expertise (leading subjective probability assessment interviews) demonstrates that performed expertise can consist of complex rule-processed knowledge forms.

Journal ArticleDOI
TL;DR: An experiment is conducted to test various hypotheses about actual behaviors of people in combining certainties for elemental operators to create an empirical base from which to launch efforts involving the acquisition of knowledge about how specific experts combine certainties at various junctures in inference processes.
