Partial Annotation Learning for Biomedical Entity Recognition

no code implementations22 May 2023 Liangping Ding, Giovanni Colavizza, Zhixiong Zhang

We harmonize 15 biomedical NER corpora encompassing five entity types to serve as a gold standard and compare against two commonly used partial annotation learning models, BiLSTM-Partial-CRF and EER-PubMedBERT, and the state-of-the-art full annotation learning BioNER model PubMedBERT tagger.
