# tner/deberta-v3-large-tweebank-ner

This model is a fine-tuned version of [microsoft/deberta-v3-large](https://huggingface.co/microsoft/deberta-v3-large) on the 
[tner/tweebank_ner](https://huggingface.co/datasets/tner/tweebank_ner) dataset.
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:
- F1 (micro): 0.7253474520185308
- Precision (micro): 0.7201051248357424
- Recall (micro): 0.7306666666666667
- F1 (macro): 0.701874697798745
- Precision (macro): 0.7043005470796733
- Recall (macro): 0.706915721861374

The per-entity breakdown of the F1 score on the test set are below:
- location: 0.7289719626168224
- organization: 0.7040816326530612
- other: 0.5182926829268293
- person: 0.856152512998267 

For F1 scores, the confidence interval is obtained by bootstrap as below:
- F1 (micro): 
    - 90%: [0.6978100031831928, 0.7529703029130037]
    - 95%: [0.691700704571692, 0.7582901338971108] 
- F1 (macro): 
    - 90%: [0.6978100031831928, 0.7529703029130037]
    - 95%: [0.691700704571692, 0.7582901338971108] 

Full evaluation can be found at [metric file of NER](https://huggingface.co/tner/deberta-v3-large-tweebank-ner/raw/main/eval/metric.json) 
and [metric file of entity span](https://huggingface.co/tner/deberta-v3-large-tweebank-ner/raw/main/eval/metric_span.json).

### Usage
This model can be used through the transformers library by 
```python
from transformers import AutoTokenizer, AutoModelForTokenClassification
tokenizer = AutoTokenizer.from_pretrained("tner/deberta-v3-large-tweebank-ner")
model = AutoModelForTokenClassification.from_pretrained("tner/deberta-v3-large-tweebank-ner")
```
but, since transformers do not support CRF layer, it is recommended to use the model via `T-NER` library. 
Install the library via pip   
```shell
pip install tner
```
and activate model as below.
```python
from tner import TransformersNER
model = TransformersNER("tner/deberta-v3-large-tweebank-ner")
model.predict("Jacob Collier is a Grammy awarded English artist from London".split(" "))
```

    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.",
