+description: Hotspot aggregation & analysis module for Sage — 11 builtin parsers, 5-dimension analysis
+category: devops
+---
+
+# Hotspot Radar Module
+
+指定来源的热点聚合分析平台。11 个内置平台解析器，4 种可配置提取器，五维分析 + 7天半衰期自动分类。
+
+## Architecture
+
+- **Repo**: `git@git.opencomputing.cn:yumoqing/hotspot.git`
+- **Tables** (6): `hotspot_source`, `hotspot_schedule`, `hotspot_fetch_log`, `hotspot_item`, `hotspot_analysis`, `hotspot_alert`
+- **Python package**: `hotspot/` — `init.py` registers on ServerEnv, `parsers.py` has 11 builtins
+- **DSPY**: `import json` + `get_sor_context(env, 'sage')` + `env.run_fetch(sor)`
+
+## Builtin Parsers (11)
+
+| parser_name | Platform | API Endpoint |
+|---|---|---|
+| weibo_hot | 微博热搜 | weibo.com/ajax/side/hotSearch |
+| zhihu_hot | 知乎热榜 | zhihu.com/api/v3/feed/topstory/hot-lists |
+| baidu_hot | 百度热搜 | top.baidu.com/board |
+| toutiao_hot | 头条热榜 | toutiao.com/hot-event/hot-board |
+| bilibili_hot | B站热门 | api.bilibili.com/x/web-interface/popular |
+| douyin_hot | 抖音热点 | 第三方聚合接口 |
+| 36kr_hot | 36氪热榜 | 36kr.com/api/search/list/info-flow/hot |
+| github_trending | GitHub | api.github.com/search/repositories |
+| hackernews | HackerNews | firebaseio.com (两步) |
+| v2ex_hot | V2EX | v2ex.com/api/topics/hot.json |
+| rsshub | RSSHub | 来源 url 即地址 |
+
+## Extractor Types (4)
+
+| parser | 场景 | parser_config 示例 |
+|--------|------|---------|
+| `builtin` | 内置平台 | `{"parser":"builtin","builtin_name":"weibo_hot"}` |
+| `json_path` | REST API | `{"parser":"json_path","item_path":"$.data.list[*]","field_map":{...}}` |
+| `css` | HTML | `{"parser":"css","item_selector":".hot-item","field_map":{...}}` |
+| `regex` | 文本 | `{"parser":"regex","item_regex":"(?P<title>...)"}` |
+| `rss` | RSS/Atom | `{"parser":"rss"}` |
+
+## 5-Dimension Analysis
+
+| 维度 | 评分依据 |
+|------|---------|
+| time (时效) | hours_alive: <1h=95, <6h=85, <24h=70 |
+| heat (热度) | heat_score: >10k=95, >5k=85, >1k=70 |
+| content (内容) | title_len + summary_len + tags + category |
+| propagation (传播) | engagement + comments×2 + shares×3 |
+| audience (受众) | total_engagement / heat_score ratio |
+
+## Status Classification
+
+```
+decay = e^(-hours_alive / 168)   # 7天半衰期
+adjusted_heat = raw_heat × decay
+hours > 336              → expired
+168 < hours ≤ 336        → cooling
+adjusted_heat > 5000     → hot
+adjusted_heat > 500      → rising (velocity>50) else emerging
+other                    → emerging
+```
+
+## Deployment
+
+```bash
+cp -r hotspot $SAGE_ROOT/
+cp models/hotspot_*.json $SAGE_ROOT/models/
+cp -r wwwroot/hotspot $SAGE_ROOT/wwwroot/
+mysql -u user -p sage < ddl/mysql.sql
+python scripts/load_path.py
+# sage.py: from hotspot.init import load_hotspot + load_hotspot()
+```
