semantic network

A semantic network is often used as a form of knowledge representation. It is a directed graph consisting of vertices, which represent concepts, and edges, which represent semantic relations between the concepts.Semantic networks are a common type of machine-readable dictionary.Important semantic relations:Meronymy (A is part of B, i.e. B has A as a part of itself)Holonymy (B is part of A, i.e. A has B as a part of itself)Hyponymy (or troponymy) (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)

<data> A graph consisting of nodes that represent physical or conceptual objects and arcs that describe the relationship between the nodes, resulting in something like a data flow diagram. Semantic nets are an effective way to represent data as they incorporate the inheritance mechanism that prevents duplication of data. That is, the meaning of a concept comes from its relationship to other concepts and the information is stored by interconnecting nodes with labelled arcs.
