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; 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; a confidence module to determine a confidence level for the suggested classification code; a difference module to receive from a user a classification code different from the suggested classification code and associated with a visual representation; a comparison module to compare the confidence level to a threshold; and a discordance module to display a discordance between the suggested classification code and the received classification code when the confidence level exceeds the threshold, comprising a discordance display module to display the visual representation of the received classification code on a different portion of the geometric shape.
