AI in Comment Analysis
AI transforms comment analysis from manual sampling to comprehensive classification. But the quality depends on what you ask AI to do.
Sentiment vs Stance Detection with AI
Basic AI sentiment: Is this positive or negative?
Advanced AI stance: Does this agree with the thesis, disagree, or is it neutral?
How PJQ Uses AI
1. Classification: Each comment gets one of 7 stance categories
2. Noise filtering: Bots, spam, and agenda-pushing are separated
3. Aggregation: Clean Mood-Net score from substantive opinions only
4. Sampling: Representative quotes for each category
