Webquence generation to incorporate hierarchy information into a target label sequence instead of the model structure. Subse-quently, we propose the Hierarchy DECoder (HiDEC), which decodes a text sequence into a sub-hierarchy sequence using recursive hierarchy decoding, classifying all parents at the same level into children at once.

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). Webrectly embed the hierarchy into a text en-coder. During training, HGCLR constructs positive samples for input text under the guid-ance of the label hierarchy. By pulling to-gether the …
