Model: specter2-review-positive
The model snsf-data/specter2-review-positive 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:
Is the sentence itself a positive statement or does it contain a positive 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: 0.89 was achieved on the validation set. The share of the outcome label amounts to 37.1%.
The fine-tuning codes are open-sourced on GitHub:

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 positive statements.
Use the code below to get started with the model.
1# import transformers library
2import transformers
3
4# load tokenizer from specter2_base - the base model
5tokenizer = transformers.AutoTokenizer.from_pretrained("allenai/specter2_base")
6
7# load the SNSF fine-tuned model for classification of positive statements in review texts
8model = transformers.AutoModelForSequenceClassification.from_pretrained("snsf-data/specter2-review-positive")
9
10# setup the classification pipeline
11classification_pipeline = transformers.TextClassificationPipeline(
12 model=model,
13 tokenizer=tokenizer,
14 return_all_scores=True
15)
16
17# prediction for an example review sentence addressing positive statement
18classification_pipeline("The strengths of this proposal are the strong applicant and team, the current dynamic nature of the field under study, and the potential impact of the work on advancing biological understanding and clinical care.")
19
20# prediction for an example review sentence not addressing positive statement
21classification_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.
