WebHierarchical text classification (HTC) aims to cate-gorize a text into a set of labels with a structured class hierarchy (commonly modeled as a tree) (Silla and Freitas,2011). HTC is a multi-label text clas-sification problem, where the classification result corresponds to one or more paths of the hierarchy (Zhou et al.,2024).
