On Cognitive Role of Negative Schema
A fundamental problem in building an intelligent agent is that an agent does not understand the meaning of its perception. However a human can perceive an object by a heuristic schema. According to Minsky, negative knowledge hidden in seemingly positive knowledge plays a controlling role in diverse areas including expert system, emotion, and search. We prove that a negated concept is defined implicitly by a hidden feature abstracted from the property common to all the objects not belonging to the concept. This paper proposes based on Minsky that there is a logical schema that enables an agent to perceive a negated concept.
