资源简介：
该数据集是通过扩展原始的MovieLens 20 million数据集生成的，包含10亿至655亿个评分，涉及270万至700万个电影和138万至1700万个用户。数据集保持了用户参与度、项目流行度和用户/项目交互矩阵的奇异值谱的肥尾分布特性，适用于推荐系统的可靠基准测试。
This dataset is generated by expanding the original MovieLens 20 Million dataset. It encompasses between 1 billion and 65.5 billion ratings, involving 2.7 million to 7 million movies and 1.38 million to 17 million users. The dataset preserves the heavy-tailed distribution characteristics of user engagement, item popularity, and the singular value spectrum of the user-item interaction matrix, making it suitable for reliable benchmarking of recommendation systems.
