tner/roberta-large-tweetner7-2020-selflabel2021-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_2021 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): 0.644817329816488
  • Precision (micro): 0.6264311416421328
  • Recall (micro): 0.6643154486586494
  • F1 (macro): 0.5941147287547678
  • Precision (macro): 0.5756979462999651
  • Recall (macro): 0.6198566504961354

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

  • corporation: 0.5058051489146896
  • creative_work: 0.4567022538552788
  • event: 0.4439876670092498
  • group: 0.6109472304162569
  • location: 0.6636304489264802
  • person: 0.8363309352517986
  • product: 0.6413994169096211

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

  • F1 (micro):
    • 90%: [0.6360417063561062, 0.6548454319775926]
    • 95%: [0.6341460646789854, 0.6560370464501823]
  • F1 (macro):
    • 90%: [0.6360417063561062, 0.6548454319775926]
    • 95%: [0.6341460646789854, 0.6560370464501823]

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-selflabel2021-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.

Training hyperparameters

The following hyperparameters were used during training:

  • dataset: ['tner/tweetner7']

  • model: tner/roberta-large-tweetner-2020
  • crf: True
  • max_length: 128
  • epoch: 30
  • batch_size: 32
  • lr: 1e-05
  • random_seed: 0

    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.",
