The contribution

Quillian represented knowledge in a connected network and described a program that searched those relations to identify meanings and draw inferences. The model treated recall as an active use of structured knowledge, making stored information useful beyond a fixed list of prewritten questions and answers.

What this does not establish

The report proposed and simulated selected semantic abilities. It did not show that a small hand-built network captured all human long-term memory.

Why this date?

1966 dates the original report. SHRDLU uses a 1966 citation label while naming the later chapter in Semantic Information Processing. The report and chapter are distinct publication versions.
