Model: specter2-review-rationale

The model snsf-data/specter2-review-rationale is based on the allenai/specter2_base model and fine-tuned for a binary classification task. In particular, the model is fine-tuned to classify if a sentence from SNSF grant peer review report is addressing the following aspect:

Does the sentence provide rationale supporting the positive or negative statement?

The model was fine-tuned based on a training set of 2'500 sentences from the SNSF grant peer review reports, which were manually annotated by multiple human annotators via majority rule. The fine-tuning was performed locally without access to the internet to prevent any potential data leakage or network interference. The following setup was used for the fine-tuning:

• Loss function: cross-entropy loss
• Optimizer: AdamW
• Weight decay: 0.01
• Learning rate: 2e-5
• Epochs: 3
• Batch size: 10
• GPU: NVIDIA RTX A2000

The model was then evaluated based on a validation set of 500 sentences, which were also manually annotated by multiple human annotators via majority rule. The resulting macro-average F1 score: 0.71 was achieved on the validation set. The share of the outcome label amounts to 18.4%.

The fine-tuning codes are open-sourced on GitHub: https://github.com/snsf-data/ml-peer-review-analysis .

Due to data privacy laws no data used for the fine-tuning can be publicly shared.

How to Get Started with the Model

The model can be used to classify sentences from grant peer review reports for addressing rationale when making positive or negative statements.

Use the code below to get started with the model.

# import transformers library
import transformers

# load tokenizer from specter2_base - the base model
tokenizer = transformers.AutoTokenizer.from_pretrained("allenai/specter2_base")

# load the SNSF fine-tuned model for classification of rationale in review texts
model = transformers.AutoModelForSequenceClassification.from_pretrained("snsf-data/specter2-review-rationale")

# setup the classification pipeline
classification_pipeline = transformers.TextClassificationPipeline(
    model=model,
    tokenizer=tokenizer,
    return_all_scores=True
)

# prediction for an example review sentence addressing rationale
classification_pipeline("Given the comments above, this reviewer considers that the proposed methods are well suited to provide key answers to the proposed hypotheses, particularly because these methods and models have provided the background knowledge justifying the reverse engineering approach.")

# prediction for an example review sentence not addressing rationale
classification_pipeline("There are currently several activities on an international level that have identified the issue and activities are underway.")
