biobert-base-cased-v1.2-finetuned-ner-CRAFT_AugmentedTransfer_EN

This model is a fine-tuned version of StivenLancheros/biobert-base-cased-v1.2-finetuned-ner-CRAFT_Augmented_EN on the CRAFTone dataset. It achieves the following results on the evaluation set:

• Loss: 0.2213
• Precision: 0.8528
• Recall: 0.8617
• F1: 0.8572
• Accuracy: 0.9709

Model description

This model performs Named Entity Recognition for 6 entity tags: Sequence, Cell, Protein, Gene, Taxon, and Chemical from the CRAFT(Colorado Richly Annotated Full Text) Corpus in Spanish and English. Entity tags have been normalized and replaced from the original three letter code to a full name e.g. B-Protein, I-Chemical. This model is trained on augmented data created using Entity Replacement. 20% of the entities were replaced using a list of entities for each entity tag obtained from the official ontologies for each entity class. Both datasets (original, augmented) were concatenated. To improve F1 score the transfer learning was completed in two steps. Using StivenLancheros/biobert-base-cased-v1.2-finetuned-ner-CRAFT_Augmented_EN as a base model, I finetuned once more on the original CRAFT dataset in English.
