UML Activity Diagram Dataset

该数据集来源于一门入门级编程课程，学生在课程中需要绘制UML活动图以实现两个二进制数的加法。数据集包含了学生策略的正确和错误轨迹。此外，对提供的提示质量进行了多评分者评估，评分者间的一致性显示为中等程度。数据规模涵盖了6种典型策略，每种策略包含2个正确轨迹和1个错误轨迹，总计364个正确状态和115个错误状态。该任务涉及的是UML活动图的创建。

This dataset is derived from an introductory programming course, where students were required to create UML activity diagrams to implement the addition of two binary numbers. It contains both correct and erroneous traces of students' problem-solving strategies. Furthermore, multi-rater evaluations were conducted to assess the quality of the provided prompts, with moderate inter-rater reliability reported. The dataset includes 6 typical strategies, each containing 2 correct traces and 1 erroneous trace, yielding a total of 364 correct states and 115 erroneous states across all collected traces. The core task of this dataset is the construction of UML activity diagrams.
