The RoBERTa2RoBERTa temporal tagger is a remarkable Seq2seq model designed for the temporal tagging of plain text using the RoBERTa language model. If you are interested in transforming your plain text into temporally annotated output, this guide is for you!
Understanding the RoBERTa Language Model
Imagine RoBERTa as an expert librarian who has read an immense number of books (a large corpus of English data) and learned to understand the context of words without needing someone to guide them every step of the way (self-supervised learning). In our scenario, RoBERTa acts as both the librarian and the assistant who sorts through the texts (as an encoder-decoder architecture) to create coherent and temporally annotated versions of the input.
Model Description
The RoBERTa2RoBERTa is built on an encoder-decoder framework, where the input is raw text and the output is the temporally annotated text. This model has been pretrained extensively on weakly annotated datasets using Heidelberg’s rule-based system, HeidelTime, and further fine-tuned on popular temporal benchmark datasets like Wikiwars, Tweets, and Tempeval-3.
How to Use the Model
Follow these simple steps to use the RoBERTa2RoBERTa Temporal Tagger:
- Load the tokenizer and model:
tokenizer = AutoTokenizer.from_pretrained('satyaalmasiantemporal_tagger_roberta2roberta')
model = EncoderDecoderModel.from_pretrained('satyaalmasiantemporal_tagger_roberta2roberta')
model_inputs = tokenizer(input_text, truncation=True, return_tensors='pt')
out = model.generate(**model_inputs)
decoded_preds = tokenizer.batch_decode(out, skip_special_tokens=True)
Fine-Tuning the Model
To fine-tune the model, follow the structure below:
trainer = Seq2SeqTrainer(
model=model2model,
tokenizer=tokenizer,
args=training_args,
compute_metrics=metrics.compute_metrics,
train_dataset=train_data,
eval_dataset=val_data,
)
train_result = trainer.train()
Make sure that the training_args
is an instance of Seq2SeqTrainingArguments
.
Training Data
During the training process, we utilized four data sources:
- Pretraining: 1 million weakly annotated samples from HeidelTime, collected from news articles dated between January 1, 2019, and July 30.
- Fine-tuning: Data from Tempeval-3, Wikiwars, and Tweets datasets.
- For data versions, refer to our repository.
Training Procedure
We started with pre-training on weakly labeled data for $3$ epochs using publicly available checkpoints on Hugging Face, specifically roberta-base
. We then proceeded to fine-tune on 3 benchmark datasets with a few nifty adjustments in the parameters.
Troubleshooting
If you encounter any issues, consider the following troubleshooting steps:
- Check if the correct version of the libraries is installed.
- Ensure that your input text is properly formatted.
- Utilize the cleaning functions provided in the repository to tidy up the model’s output.
- If outputs seem noisy or hard to interpret, consider refining the input data or adjusting your approach.
