10. A computer-implemented method for displaying visual classification suggestions for concepts, comprising the steps of: providing 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; determining for at least one of the uncoded concepts a neighborhood comprising at least one of the reference concepts; determining a classification code for the neighborhood based on the at least one of the reference concepts; suggesting the classification code of the neighborhood as a classification code for the uncoded concept, comprising displaying the visual representation of the suggested classification code placed on a portion of the geometric shape associated with the uncoded concept; determining a confidence level for the suggested classification code; receiving from a user a classification code different from the suggested classification code and associated with a visual representation; comparing the confidence level to a threshold; and displaying a discordance between the suggested classification code and the received classification code when the confidence level exceeds the threshold, comprising displaying the visual representation of the received classification code on a different portion of the geometric shape, wherein the steps are performed by a suitably programmed computer.
11. The method according to claim 10 , further comprising: receiving acceptance of the suggested classification code from a user; and upon receiving the acceptance, placing the visual representation of the suggested classification code on one of a larger portion of the geometric shape and an entirety of the geometric shape.
