# bert-base-uncased-finetuned-advanced-srl_arg |
|
|
|
This model is a fine-tuned version of [bert-base-uncased](https://huggingface.co/bert-base-uncased) on the English Universal Propbank dataset for the Semantics Role Labeling (SRL) task. |
|
It achieves the following results on the evaluation set: |
|
- Loss: 0.0914 |
|
- Precision: 0.8664 |
|
- Recall: 0.8673 |
|
- F1: 0.8669 |
|
- Accuracy: 0.9812 |
|
|
|
## Model description |
|
|
|
This more advanced SRL model uses similar apporach as the Augment method described in [NegBERT (Khandelwal, et al. 2020)](http://www.lrec-conf.org/proceedings/lrec2020/pdf/2020.lrec-1.704.pdf). |
|
That is, adding a special token ([V]) immediately before the predicate: |
|
> This [V] is a sentence. |
|
|
|
Note that **the special token and the predicate is considered a whole**. That is, the actual sentence is like |
|
> 'This' **'[V] is'** 'a' 'sentence' '.' |
|
|
|
## Usages |
|
|
|
The model labels semantics roles given input sentences. See usage examples at https://github.com/dannashao/bertsrl/blob/main/Evaluation.ipynb |
