semantic network
<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.
