## Definition

Keyword-Based Monitoring 是一种以关键词/主题为触发条件，主动搜索并追踪新内容的方法。与 [[Channel-Based Monitoring]] 的"固定频道列表"不同，它以主题为中心——适合跟踪竞品动态、技术趋势、新闻事件等泛化兴趣。

## How It Works

1. **Define keywords**: "Claude Code", "AI agents", "OpenClaw", etc.
2. **Periodic search**: AI Agent 定期通过 YouTube Search API 搜索含关键词的新视频
3. **Deduplication**: 已处理视频 ID 存入 seen-videos.txt，避免重复
4. **Transcript + Summary**: 对新视频执行 [[Transcript-Based Summarization]]
5. **Delivery**: 合并到 [[Daily-Digest]]

## Use Cases

- **竞品追踪**: 监控竞品官方频道 + 相关 KOL 频道
- **技术跟踪**: "RAG", "Fine-tuning", "vLLM" 等技术关键词
- **行业新闻**: 特定公司/产品的最新视频评论
