该数据集是一个基于Yelp评论的情感分析数据集，包含两个主要子集：yelp_review_full和yelp_review_polarity。yelp_review_full子集将Yelp评论分为1到5星评级，用于细粒度情感分析；yelp_review_polarity子集则将评论二分类为正面（1星和2星）和负面（4星和5星），忽略3星评论，用于情感极性分类。数据来源于Yelp数据集挑战赛，适用于自然语言处理任务，如情感分类和星级预测。

This dataset is a sentiment analysis dataset based on Yelp reviews, containing two main subsets: yelp_review_full and yelp_review_polarity. The yelp_review_full subset categorizes Yelp reviews into 1 to 5-star ratings for fine-grained sentiment analysis; the yelp_review_polarity subset conducts binary classification of reviews into positive (1-star and 2-star) and negative (4-star and 5-star) categories, ignoring 3-star reviews, for sentiment polarity classification. The dataset is sourced from the Yelp Dataset Challenge and is applicable to natural language processing tasks such as sentiment classification and star rating prediction.
