TaxoBell: Gaussian Box Embeddings for Self-Supervised Taxonomy Expansion

ArXi:2601.09633v2 Announce Type: replace Taxonomies form the backbone of structured knowledge representation across diverse domains, enabling applications such as e-commerce and semantic search. Yet, manual taxonomy expansion is labor-intensive and slow. Existing methods rely on point-based vector embeddings, which model symmetric similarity and thus struggle with the asymmetric relationships that are fundamental to taxonomies.
