Hierarchical Text Classification with LLM-Refined Taxonomies (2026.eacl-long)
Copied to clipboard
| Challenge: | Hierarchical text classification (HTC) relies on taxonomies that organize labels into structured hierarchies, but many real-world taxonomies introduce ambiguities, such as identical leaf names under similar parent nodes, which prevent language models from learning clear decision boundaries. |
| Approach: | They propose a framework that uses large language models to transform entire taxonomies through operations such as renaming, merging, splitting, and reordering to better match the semantics encoded by LMs. |
| Outcome: | The proposed framework outperforms human-curated taxonomies in three HTC benchmarks and shows that it aligns better with the model's actual confusion patterns. |
