# tner/bert-base-tweetner7-2020-2021-concat

This model is a fine-tuned version of [bert-base-cased](https://huggingface.co/bert-base-cased) on the 
[tner/tweetner7](https://huggingface.co/datasets/tner/tweetner7) dataset (`train_all` split).
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 of 2021:
- F1 (micro): 0.6230258640421148
- Precision (micro): 0.6166742183960127
- Recall (micro): 0.6295097132284921
- F1 (macro): 0.5758556427048315
- Precision (macro): 0.5715554663683273
- Recall (macro): 0.5821234872899773



The per-entity breakdown of the F1 score on the test set are below:
- corporation: 0.5141176470588235
- creative_work: 0.3886075949367089
- event: 0.4580617122990004
- group: 0.5660613650594865
- location: 0.6264564770390679
- person: 0.8196536144578314
- product: 0.6580310880829014 

For F1 scores, the confidence interval is obtained by bootstrap as below:
- F1 (micro): 
    - 90%: [0.6139925448708724, 0.632549139769655]
    - 95%: [0.612303125388328, 0.6336744975616968] 
- F1 (macro): 
    - 90%: [0.6139925448708724, 0.632549139769655]
    - 95%: [0.612303125388328, 0.6336744975616968] 

Full evaluation can be found at [metric file of NER](https://huggingface.co/tner/bert-base-tweetner7-2020-2021-concat/raw/main/eval/metric.json) 
and [metric file of entity span](https://huggingface.co/tner/bert-base-tweetner7-2020-2021-concat/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/bert-base-tweetner7-2020-2021-concat")
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']
 - dataset_split: train_all
 - dataset_name: None
 - local_dataset: None
 - model: bert-base-cased
 - crf: True
 - max_length: 128
 - epoch: 30
 - batch_size: 32
 - lr: 0.0001
 - random_seed: 0
 - gradient_accumulation_steps: 1
 - weight_decay: 1e-07
 - lr_warmup_step_ratio: 0.3
 - max_grad_norm: 1

The full configuration can be found at [fine-tuning parameter file](https://huggingface.co/tner/bert-base-tweetner7-2020-2021-concat/raw/main/trainer_config.json).

    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.",
