TLDR
The authors describes frame systems as a formalism for representing knowledge and then concentrates on the issue of what the content of knowledge should be in specific domains, arguing that vision should be viewed symbolically with an emphasis on forming expectations and then using details to fill in slots in those expectations.Abstract:
Briefly describes frame systems as a formalism for representing knowledge and then concentrates on the issue of what the content of knowledge should be in specific domains. Argues that vision should be viewed symbolically with an emphasis on forming expectations and then using details to fill in slots in those expectations. Discusses the enormous problem of the volume of background common sense knowledge required to understand even very simple natural language texts and suggests that networks of frames are a reasonable approach to represent such knowledge. Discusses the concept of expectation further including ways to adapt to and understand expectation failures. Argues that numerical approaches to knowledge representation are inherently limited.read more

Perceptual symbol systems.
TL;DR: A perceptual theory of knowledge can implement a fully functional conceptual system while avoiding problems associated with amodal symbol systems and implications for cognition, neuroscience, evolution, development, and artificial intelligence are explored.

Toward a model of text comprehension and production.
Walter Kintsch,Teun A. van Dijk +1 more
TL;DR: The semantic structure of texts can be described both at the local microlevel and at a more global macrolevel, and a model for text comprehension based on this notion accounts for the formation of a coherent semantic text base in terms of a cyclical process constrained by limitations of working memory.

TL;DR: In this article, the authors define a set of rhetorical schemata to be discussed in what follows, and describe them as descriptions, not definitions, and the bus schema contains information that is neither nor-

A logic for default reasoning
TL;DR: This paper proposes a logic for default reasoning, develops a complete proof theory and shows how to interface it with a top down resolution theorem prover, and provides criteria under which the revision of derived beliefs must be effected.

Self-schemata and processing information about the self.
TL;DR: In this article, the role of schemata in processing information about the self is examined by linking self-schemata to a number of specific empirical referents, and the relationship of self-schemeata to cross-situational consistency in behavior is discussed.
