The psychology has the advantage of taking a constructivist position appropriate to the modeling of specialist human knowledge but basing this on a positivist scientific position that characterizes human conceptual structures in axiomatic terms that translate directly to computational form. The repertory grid knowledge elicitation methodology is directly derived from personal construct psychology. In its original form, this methodology was based on the notion of dichotomous constructs and did not encompass the ordinal relations between them captured in semantic net elicitation. However, it was extended in successive tools developed for applied knowledge acquisition and tested in a wide variety of applications. This paper gives an overview of personal construct psychology and its expression as an intensional logic describing the cognitive processes of anticipatory agents, and uses this to survey knowledge acquisition tools deriving from personal construct psychology and to suggest how future tool architectures may be designed in an integrated fashion within this framework.
- ItemOpen AccessELICITING KNOWLEDGE AND TRANSFERRING IT EFFECTIVELY TO A KNOWLEDGE-BASED SYSTEM(1991-11-01) Gaines, Brian R.; Shaw, Mildred L.G.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 knowledge-based system is complex and involves a diversity of activities. This paper illustrates the complete development of a decision support system using knowledge acquisition tools. The example is simple enough to be completely analyzed but exhibits enough real-world characteristics to give significant insights into the processes and problems of knowledge engineering.
- ItemOpen AccessLOCALES FOR REQUIREMENTS ENGINEERING(1998-01-01) Herlea, Daniela E.; Shaw, Mildred L.G.; Gaines, Brian R.This paper presents an approach to the social interaction in requirements engineering. Giddens' concept of a sociological locale, defined as the setting for interaction, is used in understanding the interaction of people negotiating requirements. The creation of requirements engineering locales in a physical environment and the implications for designing virtual requirements engineering locales are discussed. Lessons learned from an informal study of a virtual requirements engineering environment are presented and challenges for designing computer support to requirements engineering locales are addressed.
