# tner/roberta-large-bc5cdr |
|
|
|
This model is a fine-tuned version of [roberta-large](https://huggingface.co/roberta-large) on the |
|
[tner/bc5cdr](https://huggingface.co/datasets/tner/bc5cdr) dataset. |
|
Model fine-tuning is done via [T-NER](https://github.com/asahi417/tner)'s hyper-parameter search (see the repository |
|
for more detail). It achieves the following results on the test set: |
|
- F1 (micro): 0.8840696387239609 |
|
- Precision (micro): 0.8728266269249876 |
|
- Recall (micro): 0.8956060760526048 |
|
- F1 (macro): 0.8797360472482783 |
|
- Precision (macro): 0.8684274142690976 |
|
- Recall (macro): 0.8913672531528037 |
|
|
|
The per-entity breakdown of the F1 score on the test set are below: |
|
- chemical: 0.9256943167187788 |
|
- disease: 0.8337777777777777 |
|
|
|
For F1 scores, the confidence interval is obtained by bootstrap as below: |
|
- F1 (micro): |
|
- 90%: [0.878869501707946, 0.8890795634554179] |
|
- 95%: [0.8776790106527211, 0.8897422640465147] |
|
- F1 (macro): |
|
- 90%: [0.878869501707946, 0.8890795634554179] |
|
- 95%: [0.8776790106527211, 0.8897422640465147] |

|
and [metric file of entity span](https://huggingface.co/tner/roberta-large-bc5cdr/raw/main/eval/metric_span.json). |
|
|
|
### Usage |
|
This model can be used through the [tner library](https://github.com/asahi417/tner). Install the library via pip |
|
```shell |
|
pip install tner |
|
``` |
|
and activate model as below. |
|
```python |
|
from tner import TransformersNER |
|
model = TransformersNER("tner/roberta-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. |
|
|
|
### Training hyperparameters |

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.", |
