The Reformulation Model of Expertise.
Abstract
This research develops a methodology for implementing a class of expert problem-solving programs which must create models of the problems they are given before they can apply their expert knowledge to those problems -- i.e., given a problem in their domain of expertise, these programs 'reformulate' the problem description in terms of their built-in abstract models of the domain. The implementation methodology provides the following capabilities: (1) Pieces of expert knowledge can be added to the program in a fairly independent manner without regard to their control structure implications; (2) Programs can delve through irrelevant information in the problem description to pick out only the facts needed for problem-solving; (3) Programs can model the input problem at various levels of detail, as required by the problem-solving task; and (4) Programs can tailor their expert models to the problem at hand. This is accomplished by controlling the general procedure which maps pieces of the expert model into pieces of the input with feedback information taken from the model of the input so far.
