+# JWLLL 搜索推荐算法服务
+
+这个模块包含了 JWLLL 的搜索推荐算法服务，提供以下功能：
+
+## 主要功能
+
+1. **智能搜索**
+ - 支持中文分词
+ - 拼音搜索
+ - 语义关联搜索
+ - TF-IDF 向量相似度
+ - Word2Vec 语义扩展
+
+2. **推荐算法**
+ - 基于标签的内容推荐
+ - 协同过滤推荐
+ - 个性化推荐
+
+3. **帖子管理**
+ - 帖子详情查看
+ - 点赞/取消点赞
+ - 评论功能
+ - 帖子上传
+
+## API 接口
+
+- `POST /search` - 搜索内容
+- `GET /user_tags` - 获取用户标签
+- `POST /recommend_tags` - 标签推荐
+- `POST /user_based_recommend` - 协同过滤推荐
+- `GET /post/<id>` - 获取帖子详情
+- `POST /like` - 点赞帖子
+- `POST /unlike` - 取消点赞
+- `POST /comment` - 添加评论
+- `GET /comments/<post_id>` - 获取评论
+- `POST /upload` - 上传帖子
+
+## 部署说明
+
+1. 确保安装了所有依赖：
+ ```bash
+ pip install -r requirements.txt
+ ```
+
+2. 配置数据库连接：
+ - 修改 `config.py` 中的数据库配置
+
+3. 启动服务：
+ ```bash
+ python app.py
+ ```
+
+4. 服务将在 http://127.0.0.1:5000 启动
+
+## 配置文件
+
+- `semantic_config.json` - 语义映射配置
+- `models/chinese_word2vec.bin` - Word2Vec 模型文件（可选）
+
+## 注意事项
+
+- Word2Vec 模型文件较大，如果没有可以禁用该功能
+- 确保数据库中有测试数据
+- 默认用户ID为 '3'，请确保数据库中存在该用户
