Abstract
Personal construct psychology is a theory of individual and group
psychological and social processes that has been used extensively in
knowledge acquisition research to model the cognitive processes of
human experts. 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.
