Abstract

Computer-implemented processes are disclosed for clustering items, and for using item clusters to generate and/or present item recommendations. One process involves calculating distances between items based on how the items are categorized within a hierarchical browse structure. These distance calculations may then be used as a basis for forming clusters of items.
