Researchers have introduced a novel framework for regulation-driven fine-grained hierarchical classification, designed to address complex tasks like customs tariff classification and export control categorization. This new approach, termed constraint-aware hierarchical search, converts regulatory documents into a searchable tree structure. It retrieves only valid candidate nodes and uses structured regulatory fields with evidence snippets to guide decision-making, ensuring hierarchical validity and rule consistency. Experiments on four benchmark datasets demonstrate that this method significantly outperforms existing flat classifiers and hierarchical text classification systems, achieving the best mean accuracy and providing interpretable decision paths.
