World Knowledge in Computational Models of Discourse Comprehension
Frank, Stefan L.; Koppen, Mathieu; Noordman, Leo G. M.; Vonk, Wietske
Discourse Processes: A Multidisciplinary Journal, v45 n6 p429-463 Nov 2008
Because higher level cognitive processes generally involve the use of world knowledge, computational models of these processes require the implementation of a knowledge base. This article identifies and discusses 4 strategies for dealing with world knowledge in computational models: disregarding world knowledge, "ad hoc" selection, extraction from text corpora, and implementation of all knowledge about a simplified "microworld". Each of these strategies is illustrated by a detailed discussion of a model of discourse comprehension. It is argued that seemingly successful modeling results are uninformative if knowledge is implemented ad hoc or not at all, that knowledge extracted from large text corpora is not appropriate for discourse comprehension, and that a suitable implementation can be obtained by applying the "microworld strategy." (Contains 7 footnotes, 4 figures, and 5 tables.)
