History
In 1909, Charles S. Peirce proposed a graphical notation of nodes and edges called "existential graphs" that he called "the logic of the future". This began the debate between advocates of "logic" and advocates of "semantic networks." This debate obscured the fact that semantics networks, at least those with well-defined semantics, are a form of logic.
"Semantic Nets" were first invented for computers by Richard H. Richens of the Cambridge Language Research Unit in 1956 as an "interlingua" for machine translation of natural languages.
They were developed by Robert F. Simmons and M. Ross Quillian at System Development Corporation in the early 1960s. It later featured prominently in the work of Allan M. Collins and Quillian (e.g., Collins and Quillian; Collins and Loftus Quillian )
