## 定义
基于用户互动质量而非单纯曝光量评估内容热度和可信度的评估框架。
## 权重分层
| 平台 | 权重 | 核心指标 |
|------|------|----------|
| Polymarket | 最高 | 赔率(真金白银押注,最真实) |
| Reddit | 高 | upvotes + comments |
| X (Twitter) | 高 | likes + retweets |
| YouTube | 高 | views + likes + transcripts |
| TikTok | 中 | views + likes + 标题 |
| Instagram | 中 | views + likes |
| Hacker News | 中 | points + comments |
| Web | 低 | 无互动数据,仅补充 |
## 核心洞察
- **互动数据 > 曝光数据**10万观看但无互动 ≠ 真实热度
- **押注数据 > 投票数据**Polymarket 赔率反映真实概率判断
- **评论 > 帖子**Reddit top comments 往往比标题更有价值
