🚀 LINKSCOUT COMPLETE IMPLEMENTATION - QUICK START GUIDE

✅ WHAT WAS IMPLEMENTED (100% Complete)

🤖 Reinforcement Learning System

• ✅ Backend RL endpoints (/feedback, /rl-suggestion, /rl-stats)
• ✅ Frontend feedback UI (4 buttons: Accurate/Inaccurate/Too Strict/Too Lenient)
• ✅ Real-time RL statistics display (Episodes, Accuracy, Exploration Rate)
• ✅ Automatic learning from user feedback
• ✅ Model persistence (saves to models_cache/rl_agent_model.pkl)

📊 Revolutionary Detection (8 Phases)

All phases now displayed in frontend Details tab:

1. ✅ Linguistic Fingerprint - Emotional manipulation, certainty abuse detection
2. ✅ Claim Verification - True/False/Unverifiable claim analysis
3. ✅ Source Credibility - Domain reputation scoring
4. ✅ Entity Verification - Person/organization validation, fake expert detection
5. ✅ Propaganda Detection - 18 propaganda techniques (loaded language, fear, etc.)
6. ✅ Network Verification - Cross-reference validation
7. ✅ Contradiction Detection - Logical inconsistencies, fallacies
8. ✅ Network Analysis - Bot detection, astroturfing, viral manipulation

🎯 Accuracy Improvements (per NEXT_TASKS.md)

• ✅ Database expanded to 100+ known false claims (was 20)
• ✅ ML model integrated - Custom RoBERTa model from D:\mis\misinformation_model\final
• ✅ Propaganda weight increased - Changed from 15/8 to 25/15 (67% more aggressive!)
• ✅ Expected accuracy improvement: From 48.57% → 75-85% target

🏃 HOW TO TEST (5 Minutes)

Step 1: Start Server (Terminal 1)

cd D:\mis_2\LinkScout
python combined_server.py

✅ Wait for this output:

🚀 Loading AI models...
✅ RoBERTa loaded
✅ Emotion model loaded
...
RL Agent: READY (Episodes: 0)
Server starting...
Running on http://0.0.0.0:5000

Step 2: Reload Extension

1. Open Chrome
2. Go to chrome://extensions/
3. Find LinkScout
4. Click Reload icon (🔄)
5. Click extension icon in toolbar

Step 3: Test Analysis

1. Click "Scan Page" on any news article
2. Wait 10-20 seconds for analysis
3. Check Results:
   • ✅ Percentage displayed (e.g., "45% SUSPICIOUS")
   • ✅ Overview tab shows categories, entities, what's right/wrong
   • ✅ Details tab shows 8 Revolutionary Phases (scroll down)
   • ✅ Feedback section appears at bottom

Step 4: Test RL Feedback

1. After analysis completes, scroll to bottom of popup
2. You'll see: "🤖 Help Improve Detection Accuracy"
3. Click one of 4 buttons:
   • ✅ Accurate - Analysis was correct
   • ❌ Inaccurate - Analysis was wrong
   • ⚠️ Too Strict - False positive
   • 📊 Too Lenient - Missed misinformation
4. Success message appears: "✅ Thank you! Your feedback helps improve accuracy."
5. RL Stats update: Episodes count increases

Step 5: Verify 8 Phases Display

1. Click "Details" tab
2. Scroll down past "Groq AI Research"
3. Look for header: "⚡ Revolutionary Detection System (8 Phases)"
4. Verify all 8 phases show:
   • 🔍 Phase 1: Linguistic Fingerprint
   • 📊 Phase 2: Claim Verification
   • 🌐 Phase 3: Source Credibility
   • 👤 Phase 4: Entity Verification
   • 📢 Phase 5: Propaganda Detection
   • 🔗 Phase 6: Network Verification
   • 🔄 Phase 7: Contradiction Detection
   • 🌐 Phase 8: Network Propagation Analysis

🐛 TROUBLESHOOTING

Issue: Server Won't Start

Solution:

# Check if port 5000 is in use
netstat -ano | findstr :5000

# Kill process if needed
taskkill /PID <PID> /F

# Restart server
python combined_server.py

Issue: Extension Not Working

Solution:

1. Open chrome://extensions/
2. Enable Developer mode (top right toggle)
3. Click Reload on LinkScout
4. Check console for errors: Right-click extension icon → Inspect popup
5. Look for red errors in console

Issue: Feedback Not Sending

Solution:

1. Check server terminal - should show: 📝 [RL] Received feedback: correct
2. Verify server is running on http://localhost:5000
3. Test health endpoint: Open browser → http://localhost:5000/health
4. Should see: "reinforcement_learning": {...}

Issue: 8 Phases Not Showing

Solution:

1. Click Details tab (not Overview)
2. Scroll down past AI results
3. Should see header: "⚡ Revolutionary Detection System (8 Phases)"
4. If missing, reload extension and re-analyze

Issue: RL Stats Not Updating

Solution:

1. Check server logs for errors
2. Verify /rl-stats endpoint works: http://localhost:5000/rl-stats
3. Should return JSON with total_episodes, epsilon, etc.
4. Clear browser cache and reload extension
