Function Introduction

Cloud

所有模块的父项目。

Cloud_data_load

数据导入模块

此模块负责将外源数据导入到mongoDB中。虽然实际应用时项目使用的数据库应该为电商项目长期维护的,但鉴于完整性和测试需求,外源载入数据模块也需要存在。

Cloud_kafka_app

kafka配置模块

此模块为kafka stream的启动模块。

Cloud_rec

推荐模块的父模块。

Cloud_ALS_res

基于隐语义模型的协同过滤推荐模块

此模块基于隐语义模型的协同过滤算法,根据数据库中的用户对各产品的评分,计算非实时的商品推荐列表和各商品相似度矩阵。

Cloud_Item_CF_res

基于Item-CF的离线商品相似推荐

此模块基于基于物品的协同过滤(Item-CF),只需收集用户的常规行为数据(比如点击、收藏、购买)就可以得到商品间的相似度,从而实现离线商品推荐。

Cloud_offline_rec

基于spark sql的基本离线统计

此模块完成基本的热门统计,复杂性低,只是简单的利用spark sql统计评分次数多的商品,近期评分次数多的商品,和商品的平均评分。此功能并非必须在此系统中完成,但是借助spark sql会更为简单。

Cloud_online_rec

基于实时推荐模型的实时推荐

此模块基于自定义的实时推荐模型完成商品的实施推荐服务。
