17. A system for providing a classification suggestion for a document, comprising: a database to store a corpus of documents comprising reference documents each associated with a classification and uncoded documents; a clustering engine to generate a cluster of uncoded documents; a neighborhood module to determine a neighborhood of reference documents for at least one of the uncoded documents in the cluster; a classification module to determine a classification of the neighborhood using a classifier; and a suggestion module to suggest the classification of the neighborhood as a suggested classification code for the at least one uncoded document; a difference module to assign a further classification code to the at least one uncoded document item based on instructions from a user and to identify a difference between the assigned classification code and the suggested classification code; a display module to display the difference between the assigned classification code and the suggested classification code; and a processor to execute the modules.
