7. A method for providing coded reference electronically stored information items as a suggestion for classifying uncoded electronically stored information, comprising: designating a coded reference set comprising electronically stored information items each associated with a classification code; designating clusters of uncoded electronically stored information items; comparing one or more of the uncoded electronically stored information items from at least one uncoded cluster to the coded reference set of the coded electronically stored information items; identifying at least one of the coded electronically stored information items in the coded reference set that is similar to the one or more uncoded electronically stored information items; injecting the similar coded electronically stored information items into the at least one cluster of the uncoded electronically stored information items; and visually depicting relationships between the uncoded electronically stored information items and the similar coded electronically stored information items in the at least one cluster as suggestions for classifying the uncoded electronically stored information items, wherein each of the uncoded electronically stored information items are displayed via a first symbol and each of the similar coded electronically stored information items are displayed via a second symbol.

The method according to claim 7 , further comprising: determining the similar coded electronically stored information items based on a similarity metric, comprising: forming a score vector for the one or more uncoded electronically stored information items and each coded electronically stored information item in the coded reference set; and calculating the similarity metric by comparing the score vector for the one or more uncoded electronically stored information items with the score vectors for each of the coded electronically stored information items in the coded reference set.
