Hierarchical text classification aims to leverage label hierarchy in
multi-label text classification. Existing methods encode label hierarchy in a
global view, where label hierarchy is treated as the static hierarchical
structure containing all labels. Since global hierarchy is static and
irrelevant to text samples, it makes these methods hard to exploit hierarchical
information. Contrary to global hierarchy, local hierarchy as the structured
target labels hierarchy corresponding to each text sample is dynamic and
relevant to text samples, which is ignored …
