Abstract

In the predominant symbolic approach of AI in the 1970s and early 80s, a description—such as an expert system rule, frame, script, or natural language grammar—was often called a "knowledge representation." Knowledge was viewed as something that could be inventoried. Human memory was modeled as a repository of knowledge representations. Arguments that "there are no knowledge representations in the brain," were then misinterpreted in this community as "throwing the baby out with the bathwater."
