Low-resource Taxonomy Enrichment with Pretrained Language Models

no code implementations EMNLP 2021 Kunihiro Takeoka, Kosuke Akimoto, Masafumi Oyamada

Conventional supervised methods for this enrichment task fail to find optimal parents of new terms in low-resource settings where only small taxonomies are available because of overfitting to hierarchical relationships in the taxonomies.
