| # tner/roberta-base-tweetner7-continuous |
|
|
| This model is a fine-tuned version of [tner/roberta-base-tweetner-2020](https://huggingface.co/tner/roberta-base-tweetner-2020) on the |
| [tner/tweetner7](https://huggingface.co/datasets/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](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): 0.6547126972113873 |
| - Precision (micro): 0.6592801031773947 |
| - Recall (micro): 0.6502081406105458 |
| - F1 (macro): 0.6000787312274737 |
| - Precision (macro): 0.603865779286349 |
| - Recall (macro): 0.5992466120658141 |
|
|
|
|
|
|
| The per-entity breakdown of the F1 score on the test set are below: |
| - corporation: 0.509673852957435 |
| - creative_work: 0.41677588466579296 |
| - event: 0.4675062972292191 |
| - group: 0.6152256286600069 |
| - location: 0.6798159105851413 |
| - person: 0.8448868778280542 |
| - product: 0.6666666666666667 |
| |
| For F1 scores, the confidence interval is obtained by bootstrap as below: |
| - F1 (micro): |
| - 90%: [0.6458722707634147, 0.6637540527089854] |
| - 95%: [0.6443720180740024, 0.6654476640585366] |
| - F1 (macro): |
| - 90%: [0.6458722707634147, 0.6637540527089854] |
| - 95%: [0.6443720180740024, 0.6654476640585366] |

| Full evaluation can be found at [metric file of NER](https://huggingface.co/tner/roberta-base-tweetner7-continuous/raw/main/eval/metric.json) |
| and [metric file of entity span](https://huggingface.co/tner/roberta-base-tweetner7-continuous/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 |
| ``` |
| [TweetNER7](https://huggingface.co/datasets/tner/tweetner7) pre-processed tweets where the account name and URLs are |
| converted into special formats (see the dataset page for more detail), so we process tweets accordingly and then run the model prediction as below. |
| |
| ```python |
| import re |
| from urlextract import URLExtract |
| from tner import TransformersNER |
| |
| extractor = URLExtract() |
| |
| def format_tweet(tweet): |
| # mask web urls |
| urls = extractor.find_urls(tweet) |
| for url in urls: |
| tweet = tweet.replace(url, "{{URL}}") |
| # format twitter account |
| tweet = re.sub(r"\b(\s*)(@[\S]+)\b", r'\1{\2@}', tweet) |
| return tweet |
| |
|
|
| text = "Get the all-analog Classic Vinyl Edition of `Takin' Off` Album from @herbiehancock via @bluenoterecords link below: http://bluenote.lnk.to/AlbumOfTheWeek" |
| text_format = format_tweet(text) |
| model = TransformersNER("tner/roberta-base-tweetner7-continuous") |
| model.predict([text_format]) |
| ``` |
| 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_2021 |
| - dataset_name: None |
| - local_dataset: None |
| - model: tner/roberta-base-tweetner-2020 |
| - crf: True |
| - max_length: 128 |
| - epoch: 30 |
| - batch_size: 32 |
| - lr: 1e-06 |
| - random_seed: 0 |
| - gradient_accumulation_steps: 1 |
| - weight_decay: 1e-07 |
| - lr_warmup_step_ratio: 0.15 |
| - max_grad_norm: 1 |
|
|
| The full configuration can be found at [fine-tuning parameter file](https://huggingface.co/tner/roberta-base-tweetner7-continuous/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.", |
