Model: specter2-review-applicant

The model snsf-data/specter2-review-applicant 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 address the applicant(s)/team or their qualifications, without mentioning quantitative indicators?

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: 0.91 was achieved on the validation set. The share of the outcome label amounts to 19.7%.

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 the applicant(s)/team or their qualifications, without mentioning quantitative indicators.

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 the applicant in review texts
model = transformers.AutoModelForSequenceClassification.from_pretrained("snsf-data/specter2-review-applicant")

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

# prediction for an example review sentence addressing the applicant
classification_pipeline("Therefore, they have ability to carry out the proposed project based on their strong expertise in this special research area and their outstanding track record.")

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

Model Limitations

• Human Assessment Required: This model should not be used for automatic classification of grant peer review reports without human oversight.
• Limited Training Data: The model was fine-tuned on a limited sample of 2,500 annotated sentences. Therefore, its classification accuracy should be critically evaluated before deployment.
• Specific Training Data: The training data consists of a random sample of SNSF grant peer review reports. As such, the model's external validity to other datasets may be limited.
