1. A computer-implemented system for displaying visual classification suggestions for concepts, comprising: a processor to execute modules, comprising: a clustering module to provide at least one cluster comprising one or more uncoded concepts, each associated with a visual representation comprising a geometric shape, and one or more reference concepts, each associated with a visual representation of an assigned classification code; a neighborhood module to determine for at least one of the uncoded concepts a neighborhood comprising at least one of the reference concepts; a classification module to determine a classification code for the neighborhood based on the at least one of the reference concepts; and a suggestion module to suggest the classification code of the neighborhood as a classification code for the uncoded concept, comprising a display module to display the visual representation of the suggested classification code placed on a portion of the geometric shape associated with the uncoded concept.
