Papers:
Hayes P, The logic of frames
Shubert L, Semantic nets are in the eye of
the beholder
Davis R, Shrobe H, Szolovits P, What is a
Knowledge Representation?
1. We claim that the first two of these papers
miss something important about knowledge representation. They both claim to be critiques of a
representation mechanism and both take a kind of reductionist view, claiming
that when examined closely, the representation has less than meets the
eye. Both use logic as a kind of testing
ground; the Shubert paper has a slightly less narrow field of view.
a. In what way does the reduction to logic
prove Hayes’ claim?
b. What is Hayes’ definition of a
representation, and how is this definition linked to his claim?
c. What elements of the
2. The basic argument in the Davis, et. al. paper is that a knowledge representation performs
five important roles and that ignoring any one of them is a bad idea.
a. What are the five roles?
b. Pick any representation (e.g. rules,
frames, semantic nets, etc.) and describe the roles with respect to that
representation.
