一个包含1000条用户-物品交互记录的样本数据集，用于TAAC2026竞赛。数据集采用扁平列布局，所有特征都作为单独的顶级列存储，而非嵌套结构。数据集包含120列，分为6大类：ID与标签（5列）、用户整数特征（46列）、用户密集特征（10列）、物品整数特征（14列）和领域序列特征（45列）。A sample dataset containing 1000 user-item interaction records for the TAAC2026 competition. This dataset uses a flat column layout — all features are stored as individual top-level columns instead of nested structs/arrays. The dataset includes 120 columns categorized into 6 groups: ID & Label (5 columns), User Int Features (46 columns), User Dense Features (10 columns), Item Int Features (14 columns), and Domain Sequence Features (45 columns).
