news_text_classification's Introduction

零基础入门NLP-新闻文本分类

🎯比赛地址
文本分类的任务是将给定的文本划分到事先规定的文本类别。

  • 赛题难度
    • 匿名数据 + 长文本 + 类别不均衡
  • 解题思路:
    • 思路1:TF-IDF提取特征 + SVM分类
    • 思路2:训练FastText词向量并分类
    • 思路3:训练Word2Vec词向量 + TextCNN模型分类
    • 思路4:训练BERT词向量并分类
    • 思路5:BERT分类 + 统计特征的树模型
    • 思路6:......
      不平衡类别数据
  1. 赛题中每个新闻包含的字符个数平均为1000个,还有一些新闻字符较长;
  2. 赛题中新闻类别分布不均衡,科技类新闻样本量接近4万,星座类新闻(13)样本量不到1千;
  3. 赛题总共包括7000-8000个字符。

🛴利用BERT + 全局平均池化进行新闻文本分类

🛴利用BERT+BI-LSTM进行新闻文本分类
