LessonLink

该数据集名为LessonLink，包含了与SAT数学练习题相链接的真实世界辅导课程转录文本。这些文本被细分为总共3,500个片段，并涵盖了超过24,300分钟的教学内容。该数据集源自一个为期四周的SAT数学强化训练营，期间辅导老师与小组成员进行会面，并将课程录音。为了研究目的，已对去身份化的转录文本进行了分享。数据规模包括3,500个片段，1,300位独特的发言者，以及与116个SAT数学问题相链接。该数据集的任务是面向问题的分割与检索（Posr）。

This dataset, named LessonLink, comprises real-world tutorial course transcripts linked to SAT math practice questions. These transcripts are segmented into a total of 3,500 segments, encompassing over 24,300 minutes of instructional content. This dataset is derived from a four-week SAT math intensive bootcamp, where tutors held sessions with small groups of students and recorded the course content. De-identified transcripts have been shared for research purposes. The dataset includes 3,500 segments, 1,300 unique speakers, and connections to 116 SAT math questions. The task associated with this dataset is Problem-Oriented Segmentation and Retrieval (POSR).
