Semantic memory/network

Basic ideas were presented by Allan M. Collins; M.R. Quillian (1969). "Retrieval time from semantic memory"

• Semantic memory is knowledge of facts
• Each node has specific meaning
• SNs employ the local representation of concepts
• A node's activity may spread along links to activate other nodes (spreading activation)
• Spreading activation may lose strength as it travels outward from the source
• Distance between 2 nodes (concepts) is related to their relatedness

Conceptual graphs.
Conceptual graphs (CGs) are a system of logic based on the existential graphs of Charles Sanders Peirce and the semantic networks of artificial intelligence.
