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. (1999-01-07)
