tner/twitter-roberta-base-dec2020-tweetner7-2020-2021-continuous
This model is a fine-tuned version of tner/twitter-roberta-base-dec2020-tweetner-2020 on the
tner/tweetner7 dataset (train_2021 split). The model is first fine-tuned on train_2020, and then continuously fine-tuned on train_2021.
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): 0.655146764318819
- Precision (micro): 0.6484313059236607
- Recall (micro): 0.6620027752081407
- F1 (macro): 0.60565538970149
- Precision (macro): 0.5978135601251405
- Recall (macro): 0.6152969312272543
The per-entity breakdown of the F1 score on the test set are below:
- corporation: 0.5356371490280778
- creative_work: 0.4529526281635302
- event: 0.4692272096251735
- group: 0.610738255033557
- location: 0.6627831715210356
- person: 0.8433472499546196
- product: 0.6649020645844361
For F1 scores, the confidence interval is obtained by bootstrap as below:
- F1 (micro):
- 90%: [0.646485917836786, 0.6644401423537809]
- 95%: [0.6449507873997479, 0.6659444015725502]
- F1 (macro):
- 90%: [0.646485917836786, 0.6644401423537809]
- 95%: [0.6449507873997479, 0.6659444015725502]

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/twitter-roberta-base-dec2020-tweetner7-2020-2021-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.",
