运行模式

standalone 模式

SDK

数据推送与推荐接口交互 client ，目前仅支持 java 版本

rec-server

推荐系统在线服务，整合实时数据链路、运营操作以及召回+排序链路，完成整套推荐系统在线服务功能串通

rec-algorithm

推荐算法模块，基于 pandas 实现，故而目前仅支持单机环境：包含 i2i,word2vec,hot 以及 new 四种召回算法

recall-engine

推荐召回引擎，包括两部分

redis：用户 i2i,hot,new 以及曝光过滤等
elasticsearch：用于向量召回以及文本检索

example

顾名思义，为了使开发者更容易的了解整套链路的工作流程而准备的辅助模块

cluster 模式

主要是 rec-algorithm 以及实时链路部分会进行集群版本的扩充，挖个坑先... 先将 standalone 版本放出来试试水，尝试搜集下需求和建议，当然如果能一起参与开发就更好了，说实话一个人搞还是蛮累的...

演示说明

使用了开放的豆瓣数据集，由于太大没有上传至 git
其中包含用户数据 64w+，物品数据 14w+，行为数据 210w+ 测试效果：
