Method and system for item line assignment

A price assignment system for linking items into line groups comprising:

• an item database comprising a plurality of records for existing items, each record comprising a line identifier and one or more item attributes;
• an unassigned items queue comprising a plurality of records for unassigned items, each record comprising one or more item attributes;
• a line recommendation engine configured to receive an unassigned item record from the queue and to store one or more line recommendations for the unassigned item record in a recommendation database,
• wherein the line recommendation engine comprises a new line detection engine comprising a single-class support vector model trained with the plurality of records for existing items to determine a blueprint of assignable item attributes, the new line detection engine configured to generate a new line recommendation record in the recommendation database when the item attributes of the unassigned item record do not match the blueprint of assignable item attribute, and
• wherein the line recommendation engine further comprises an existing line matching engine comprising a nearest neighbor evaluator configured to generate one or more existing line recommendation records in the recommendation database, each existing line recommendation comprising a line identifier associated with one or more existing item records having item attributes similar to the item attributes of the unassigned item record;
• a user interface configured to display the one or more line recommendations for the unassigned item record to a user and to receive an input indicating a selected line identifier for the unassigned item record;
• a selection processing engine configured to update the item database with the unassigned item record and the selected line identifier;
• and
• a machine learning engine configured to modify a parameter of the line recommendation engine based on the selected line identifier.
