-# InsightRadar
-An AI-powered trend monitoring and news intelligence platform
+# 聚势智见 — 基于语义聚类与大模型的热点资讯聚合平台
+
+一个智能热点监测与个性化分发平台，通过语义聚类与大模型技术，将分散在微博、知乎、抖音、百度等平台的热点资讯自动归并为统一事件，生成AI摘要与标签，并支持个性化订阅与定时推送。
+
+## 核心特性
+
+- **跨平台热点聚合**：基于Embedding语义相似度计算，自动识别不同平台的同一事件
+- **AI智能摘要**：调用大模型生成统一标题、综合摘要与标准化标签
+- **个性化推荐**：支持关键词订阅、语义匹配与多因子排序
+- **舆情分析工具**：提供热度趋势追踪、标题修改监控、时间线分析
+- **定时简报推送**：自定义推送时间与接收邮箱，生成个性化AI简报
+
+## 快速部署
+
+### 方式一：Docker部署（推荐）
+
+**环境要求**
+- Linux系统（推荐Ubuntu 22.04 LTS / Debian 12）
+- Docker ≥ 20.10.0，Docker Compose v2
+- 内存 ≥ 512MB（建议1GB以上）
+
+**部署步骤**
+
+```bash
+# 1. 构建镜像
+docker build -t insightradar:latest .
+
+# 2. 配置目录（参考docker/ereadm.txt）
+mkdir -p ./data ./logs
+
+# 3. 启动服务
+cd docker
+docker compose up -d
+```
+
+### 方式二：源码部署
+
+**环境要求**
+
+- Python ≥ 3.11，uv包管理器
+- Node.js ≥ 22
+- 内存 ≥ 512MB
+
+**后端部署**
+
+``` bash
+# 复制
+cd backend
+uv sync
+uv run
+```
+
+**前端部署**
+
+```bash
+# 复制
+cd frontend
+npm install
+npm run build
+# 将dist/目录内容复制到 backend/app/static/
+```
+
+**配置说明**
+
+- 复制 .env.example 为 .env 并填写配置
+- 将Embedding模型（Qwen3-Embedding-4B）放入 backend/data/ 目录
+
+### 访问应用
