# Model: specter2-review-applicant-quantity

The model `snsf-data/specter2-review-applicant-quantity` 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 use quantitative indicators to describe the applicant(s) or team?***

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: 0.93** was achieved on the validation set. The share of the outcome label amounts to 1.6%.

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 quantitative indicators to describe the applicant(s)or team.

Use the code below to get started with the model.

```python
# 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 quantitative indicators related to the applicant
model = transformers.AutoModelForSequenceClassification.from_pretrained("snsf-data/specter2-review-applicant-quantity")

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

# prediction for an example review sentence addressing quantitative indicators related to the applicant
classification_pipeline("He is first author of eight manuscripts and reviews and for four manuscript he is last author, and in addition he is joint last author on one additional manuscript.")

# prediction for an example review sentence not addressing quantitative indicators related to 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.
