Semantic Networks
A graph structure for representing knowledge through interconnected concepts.
Why It Was Important
Developed primarily by Ross Quillian, semantic networks represent meaning as a graph where nodes represent concepts and edges represent semantic relations (e.g., 'is-a', 'has-a'). This architecture strongly influenced modern knowledge representation, ontologies, and the Knowledge Graph used by search engines today.
Who Invented It
