What is semantic network in artificial intelligence?

Answer»

A semantic network, or frame network is a knowledge base that represents semanticrelations between concepts in a network. This is often used as a form of knowledge representation. It is a directed or undirected graph consisting of vertices, which represent concepts, and edges, which represent semantic relations between concepts.[1]

Typical standardized semantic networks are expressed as semantic triples.

Semantic networks are in use in various Natural Language Processing applications.

History



Example of a semantic network

"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.[2]

They were independently developed by Robert F. Simmons,[3] Sheldon Klein, Karen McConologue, M. Ross Quillian[4] and others at System Development Corporation in the early 1960s as part of the SYNTHEX project. It later FEATURED prominently in the work of Allan M. COLLINS and Quillian (e.g., Collins and Quillian;[5][6] Collins and Loftus[7] Quillian[8][9][10][11]). Later in 2006, Hermann Helbig fully described MultiNet[12].
