自然语言处理的情感分析:从Bag of Words到Deep Learning,1.背景介绍自然语言处理(NLP)是计算机科学与人工智能中的一个分支,旨在让计算机理解、生成和处理人类语言。情感分析是
Now, let's get to the star of the show – the Bag of Words technique, often abbreviated as BoW. BoW is like the Lego bricks of NLP. It's a simple yet powerful method that allows us to convert chunks of text into manageable pieces that machines can work with. With BoW, we break d...
可能原因分析:可能是超参数没有调好(bert输入参数没有完全理解透彻,后续还要跟进,另外可以研究bert的loss的可视化输出,网上有修改的源码),也可能是没有用上语料库的原因,总之效果并不理想 综上,两段代码都有需要改进的地方,未来值得深究(另外备注一点:bert还可以做多标签情感分类,多标签情感分类属于另一主题,留给未...

Most sentiment analysis approaches rely on machine-learning techniques, using a bag-of-words (BoW) document representation as their basis. In this paper, we examine whether a more fine-grained representation of documents as sequences of emotionally-annotated sentences can increase document classification...
