Semantic network

A semantic network is often used as a form of knowledge representation. It consists of vertices which represent concepts and edges which represent relations between the concepts.

Important semantic relations:

• Meronymy (A is part of B)
• Hyponymy (A is subordinate of B; A is kind of B)
• Hypernymy (A is superordinate of B)
• Synonymy (A denotes the same as B)
• Antonymy (A denotes the opposite of B)

An example of a semantic network is [[wordnet]], a lexical database of English.
