Model Card for Misogyny Detection in Italian

This model is a fine-tuned version of dbmdz/bert-base-italian-xxl-uncased for the task of misogyny detection in Italian text. It identifies whether a given text contains misogynistic content (label 1) or not (label 0). The model has been trained and evaluated on the AMI (Automatic Misogyny Identification) dataset.

Model Details

Model Description

• Developed by: Lorenzo Maiuri
• Funded by: No funds
• Shared by: Lorenzo Maiuri
• Model type: Text Classification
• Language(s): Italian (it)
• License: CC BY-NC-SA 4.0
• Fine-tuned from model: dbmdz/bert-base-italian-xxl-uncased

This model is specifically designed for detecting misogynistic content in Italian, making it useful for tasks in moderation, social media analysis, or sociolinguistic studies.

Uses

Direct Use

This model can be used as-is for binary text classification to detect misogyny in Italian. For example:

from transformers import pipeline

classifier = pipeline("text-classification", model="maiurilorenzo/misogyny-detection-it")
output = classifier("Questo è un esempio di testo misogino.")
print(output)

Downstream Use

The model can be fine-tuned further on related datasets for similar tasks, such as hate speech detection, sentiment analysis, or offensive language detection.

Out-of-Scope Use

• The model is not intended for use in tasks outside of text classification.
• Avoid applying the model to non-Italian texts, as it may produce unreliable results.
• Misuse for harmful, malicious, or discriminatory purposes is strictly prohibited.

Bias, Risks, and Limitations

The model inherits potential biases present in the AMI dataset. It may overfit to linguistic patterns commonly associated with misogyny in the training data and fail to generalize to less explicit forms of misogyny or more nuanced cultural contexts.

Recommendations

• Use the model in conjunction with human moderation for critical tasks.
• Regularly evaluate the model on updated or domain-specific datasets to ensure continued accuracy and fairness.

How to Get Started with the Model

Use the code below to get started with the model:

from transformers import pipeline

classifier = pipeline("text-classification", model="maiurilorenzo/misogyny-detection-it")
output = classifier("Esempio di testo italiano.")
print(output)

Training Details

Training Data

The model was fine-tuned using the AMI (Automatic Misogyny Identification) dataset, which contains labeled examples of misogynistic and non-misogynistic texts in Italian.

• Dataset license: CC BY-NC-SA 4.0
• The training set was balanced by splitting misogynistic and non-misogynistic examples into training and validation sets.

Training Procedure

• Kaggle Notebook: Link to Kaggle Notebook

Preprocessing

The text was tokenized using the BERT tokenizer, with a maximum sequence length of 128 tokens. Labels were mapped to the labels field as required by the Transformers library.

Training Hyperparameters

• Learning Rate: 2e-5
• Batch Size: 32
• Epochs: 5
• Evaluation Strategy: Per epoch
• Metric for Best Model: F1-score
• Optimizer: AdamW with weight decay 0.01

Total Training Time: Approximately 15 minutes Hardware Used: RTX 2060

Evaluation

Testing Data, Factors & Metrics

Testing Data

The model was evaluated on the test split of the AMI dataset, which is balanced and contains examples of both misogynistic and non-misogynistic content.

Factors

The evaluation considers factors such as:

• Lexical variations
• Explicit vs. implicit misogyny
• Variations in Italian regional language

Metrics

The following metrics were computed for evaluation:

• Accuracy
• F1-score
• Precision
• Recall

Results

• Accuracy: 0.9412
• F1-score: 0.9420
• Precision: 0.9291
• Recall: 0.9553

Summary

The model achieves strong performance on explicit misogyny detection, with potential for improvement in detecting more subtle or implicit forms of misogyny.
