Rank, Chunk and Expand: Lineage-Oriented Reasoning for Taxonomy Expansion (2025.findings-acl)

Copied to clipboard

Challenge: Existing taxonomy expansion methods struggle with representation limits and generalization, while generative methods process all candidates at once, introducing noise and exceeding context limits.
Approach: They propose a plug-and-play framework that combines discriminative ranking and generative reasoning for efficient taxonomy expansion.
Outcome: Experiments show that LORex improves accuracy by 12% and similarity by 5% over state-of-the-art methods.
