tner/deberta-v3-large-bc5cdr

This model is a fine-tuned version of microsoft/deberta-v3-large on the tner/bc5cdr dataset. Model fine-tuning is done via T-NER 's hyper-parameter search (see the repository for more detail). It achieves the following results on the test set:

• F1 (micro): 0.8902493653874869
• Precision (micro): 0.8697724178175452
• Recall (micro): 0.9117137322866755
• F1 (macro): 0.8863403908610603
• Precision (macro): 0.8657302393432342
• Recall (macro): 0.9080747413030301

The per-entity breakdown of the F1 score on the test set are below:

• chemical: 0.9298502009499452
• disease: 0.8428305807721753

For F1 scores, the confidence interval is obtained by bootstrap as below:

• F1 (micro):
  • 90%: [0.885162383660078, 0.8951239957151518]
  • 95%: [0.8838793313408008, 0.8959517574197015]
• F1 (macro):
  • 90%: [0.885162383660078, 0.8951239957151518]
  • 95%: [0.8838793313408008, 0.8959517574197015]

Usage

This model can be used through the tner library . Install the library via pip

pip install tner

and activate model as below.

from tner import TransformersNER
model = TransformersNER("tner/deberta-v3-large-bc5cdr")
model.predict(["Jacob Collier is a Grammy awarded English artist from London"])

It can be used via transformers library but it is not recommended as CRF layer is not supported at the moment.

    abstract = "Language model (LM) pretraining has led to consistent improvements in many NLP downstream tasks, including named entity recognition (NER). In this paper, we present T-NER (Transformer-based Named Entity Recognition), a Python library for NER LM finetuning. In addition to its practical utility, T-NER facilitates the study and investigation of the cross-domain and cross-lingual generalization ability of LMs finetuned on NER. Our library also provides a web app where users can get model predictions interactively for arbitrary text, which facilitates qualitative model evaluation for non-expert programmers. We show the potential of the library by compiling nine public NER datasets into a unified format and evaluating the cross-domain and cross- lingual performance across the datasets. The results from our initial experiments show that in-domain performance is generally competitive across datasets. However, cross-domain generalization is challenging even with a large pretrained LM, which has nevertheless capacity to learn domain-specific features if fine- tuned on a combined dataset. To facilitate future research, we also release all our LM checkpoints via the Hugging Face model hub.",
