tner/roberta-large-tweetner7-2020-selflabel2020-continuous
This model is a fine-tuned version of tner/roberta-large-tweetner-2020 on the
tner/tweetner7 dataset (train split). This model is fine-tuned on self-labeled dataset which is the extra_2020 split of the tner/tweetner7 annotated by tner/roberta-large). Please check https://github.com/asahi417/tner/tree/master/examples/tweetner7_paper#model-fine-tuning-self-labeling for more detail of reproducing the model. The model is first fine-tuned on train_2020, and then continuously fine-tuned on the self-labeled 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 of 2021:
- F1 (micro): 0.6514522821576764
- Precision (micro): 0.6323753537992598
- Recall (micro): 0.6717160037002775
- F1 (macro): 0.6022910652688035
- Precision (macro): 0.5829347583676058
- Recall (macro): 0.6268182581614908
The per-entity breakdown of the F1 score on the test set are below:
- corporation: 0.5252837977296182
- creative_work: 0.4650306748466258
- event: 0.46176911544227883
- group: 0.608667941363926
- location: 0.6666666666666666
- person: 0.8382696104828578
- product: 0.6503496503496504
For F1 scores, the confidence interval is obtained by bootstrap as below:
- F1 (micro):
- 90%: [0.6429569959405362, 0.6605302879870334]
- 95%: [0.6410815271146394, 0.6628490227012314]
- F1 (macro):
- 90%: [0.6429569959405362, 0.6605302879870334]
- 95%: [0.6410815271146394, 0.6628490227012314]

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/roberta-large-tweetner7-2020-selflabel2020-continuous")
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.",
