# tner/bertweet-large-wnut2017
This model is a fine-tuned version of [vinai/bertweet-large]( on the
[tner/wnut2017]( 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): 0.5302273987798114
- Precision (micro): 0.6602209944751382
- Recall (micro): 0.44300278035217794
- F1 (macro): 0.4643459997680019
- Precision (macro): 0.5792841925426832
- Recall (macro): 0.3973128655628379
The per-entity breakdown of the F1 score on the test set are below:
- corporation: 0.3902439024390244
- group: 0.37130801687763715
- location: 0.6595744680851063
- person: 0.65474552957359
- product: 0.2857142857142857
- work_of_art: 0.4244897959183674
For F1 scores, the confidence interval is obtained by bootstrap as below:
- F1 (micro):
- 90%: [0.5002577319587629, 0.5587481638299118]
- 95%: [0.4947163587619384, 0.5629013150503995]
- F1 (macro):
- 90%: [0.5002577319587629, 0.5587481638299118]
- 95%: [0.4947163587619384, 0.5629013150503995]

and [metric file of entity span](
### 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/bertweet-large-wnut2017")
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.",
