US Patent 11676193 Optimizing diversity and relevance for catalog items

Methods, systems, and computer-readable media for optimizing diversity and relevance for catalog items are disclosed. Respective target metrics are determined for a plurality of categories comprising a plurality of items in an electronic catalog. First and second categories comprise first and second subsets of the plurality of items, and the respective target metric for the first category is determined using aggregation of individual target metrics for the first subset. Respective similarity scores are determined between pairs of the categories. N item categories are selected from the plurality of categories based at least in part on the respective target metrics and based at least in part on the respective similarity scores. A third subset of the plurality of items is selected from across the N item categories, including the first and second categories. The selected items optimize both category diversity and item relevance.
