一、预测分析·商品评论情感预测

竞赛地址： https://www.heywhale.com/home/competition/609cc718ca31cd0017835fdc/content/1 希望大家用PaddleNLP把它打趴下，地下爬。。。。。。

1.背景

众所周知，大数据是企业的基本生产资料，数据信息是企业 宝贵的资产。不同于其他资产，数据资产主要在企业运营过程中 产生，较易获取，但要持续积累、沉淀和做好管理却并不容易， 这是一项长期且系统性的工程。未经“雕琢”的数据是一组无序、 混乱的数字，并不能给企业带来何种价值，从庞杂晦涩的数据中 挖掘出“宝藏”充满着挑战，这需要将业务、技术与管理三者相 互融合起来进行创新。

随着网上购物越来越流行，人们对于网上购物的需求变得越来越高，这让京东，淘宝等电商平台得到了很大的发展机遇。但是，这种需求也推动了更多的电商平台的发展，引发了激烈的竞争。在这种电商平台激烈竞争的大背景下，除了提高商品质量，压低商品价格外，了解更多的消费者心声对于电商平台来说也越来越重要。其中非常重要的一种方式就是针对消费者的购物行为数据和文本评论数据进行内在信息的数据挖掘分析。而得到这些信息，也有利于对应商品的生产自身竞争力的提高，以及为用户提供高质量感兴趣的商品。

2.数据简介

• 本数据集包括52 万件商品，1100 多个类目，142 万用户，720 万条评论/评分数据
• 本次练习赛所使用数据集基于JD的电商数据，来自WWW的JD.com E-Commerce Data，并且针对部分字段做出了一定的调整，所有的字段信息请以本练习赛提供的字段信息为准
• 评分为[1,5] 之间的整数
