Automated Category Tree Construction in E-Commerce

Summary: Formalizes category-tree construction under item-category bounds to maximize similarity to candidate categories. Two heuristics beat worst-case bounds; a case has tight guarantees, with updates preserving tree consistency via search-query candidates. (summarized by gpt-5-nano on Feb 09 2026)
