semantic network
semantic network (data)A graph consisting of nodes that represent physicalor conceptual objects and arcs that describe the relationshipbetween the nodes, resulting in something like a data flowdiagram. Semantic nets are an effective way to represent dataas they incorporate the inheritance mechanism that preventsduplication of data. That is, the meaning of a concept comesfrom its relationship to other concepts and the information isstored by interconnecting nodes with labelled arcs.EncyclopediaSees:n |
