2. A system, comprising: at least one hardware computing device; and an item classification application executable in the at least one hardware computing device, the item classification application comprising: logic that identifies one of a plurality of classifications based at least in part on data associated with an item and a data dictionary, thereby producing an identified classification that is associated with a confidence score; logic that automatically assigns the identified classification to the item when the confidence score meets a threshold; logic that obtains a manual confirmation of the identified classification when the confidence score is below the threshold, the manual confirmation indicating whether the identified classification is correct; logic that builds the data dictionary based at least in part on data describing a plurality of preclassified items, each one of the preclassified items being assigned a manually determined one of the classifications; and logic that periodically rebuilds the data dictionary based at least in part on data associated with automatically classified items haying manually confirmed classifications.

The system of claim 2 , wherein the identified classification is identified based at least in part on a plurality of preclassified tokens, each one of the preclassified tokens being assigned a manually determined one of the classifications.
