bert-base-uncased-finetuned-advanced-srl_arg

This model is a fine-tuned version of 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). 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
