Jupyter Notebook

from claudette_bias_detector import BiasDetector
import pandas as pd

detector = BiasDetector()

# Analyze DataFrame column
df['bias_score'] = df['text'].apply(lambda x: detector.analyze(x).overall_score)
df['biases_found'] = df['text'].apply(lambda x: len(detector.analyze(x).detected_biases))

# Visualize
df[['text', 'bias_score', 'biases_found']].head()

Web Application

// Express.js integration
const axios = require('axios');

app.post('/check-bias', async (req, res) => {
  const { text } = req.body;

  const result = await axios.post('http://localhost:3000/api/analyze', {

  });

  res.json(result.data);
});

🛡️ Privacy & Ethics

Data Handling

• ✅ No text content is stored by default
• ✅ Optional anonymous usage statistics
• ✅ All processing is local (no external API calls)
• ✅ GDPR compliant

Ethical Considerations

• This tool is designed to assist, not replace human judgment
• Bias detection is probabilistic and context-dependent
• Always review suggestions before applying changes
• Tool should be used to improve fairness, not to censor legitimate viewpoints

🐛 Known Limitations

1. Context Dependency: May miss context-specific biases
2. Cultural Nuances: Optimized for Western cultural contexts
3. Sarcasm/Irony: May not detect bias in heavily ironic text
4. Domain Specificity: May need tuning for highly technical domains
5. Language Support: Better accuracy in English than other languages

We're actively working to improve these areas. Contributions welcome!
