该数据集包含了5万条极具情感极性的电影评论，这些评论被分为正面和负面两类，且每条评论的二进制特征向量大小不一。具体来说，二进制特征向量分别以5000（I1）、10000（I2）、15000（I3）和20000（I4）个特征的大小进行创建。整个数据集规模为5万条评论，其任务是进行情感分析。
This dataset contains 50,000 movie reviews with distinct emotional polarities, which are classified into two classes: positive and negative. Each review is associated with a binary feature vector of varying dimensions. Specifically, four variants of binary feature vectors are constructed with 5000 (I1), 10000 (I2), 15000 (I3) and 20000 (I4) features respectively. The entire dataset comprises 50,000 reviews, and its core task is sentiment analysis.
