+ # MITFLD: MIT Lecture Fragmentation Dataset
2
+
3
+ MITFLD is a **lecture video fragmentation dataset** introduced in [_Towards Key Point Identification (KPI) for Lecture Videos: Approaches and Performance Evaluation_](https://doi.org/10.1145/3746640), serving as a **benchmark for lecture video fragmentation methods** without using synthetic videos.
4
+
5
+ It enables research in:
6
+
7
+ - **Key Point Identification (KPI) in lecture videos**
8
+ - Lecture fragment recommendation
9
+ - Non-linear and bite-sized learning
10
+ - Content-based indexing and search for lecture videos
11
+
12
+ ## Data Source Attribution
13
+
14
+ The MITFLD dataset is **sourced from [MIT OpenCourseWare](https://ocw.mit.edu/)**, a free and open publication of material from thousands of MIT courses, enabling global access to high-quality educational resources.

+ ## KPI Framework
30
+
31
+ To facilitate experiments, the dataset is designed to work seamlessly with the **[kpi](https://bit.ly/kpi_lecture_frag) unified Python framework** for lecture video fragmentation, providing:
32
+
33
+ - Dataset abstractions
34
+ - Multiple baseline and advanced methods (e.g., BiLSTM, TW-FINCH, PSD)
35
+ - Evaluation metrics (F-score, mMoF, mIoU)
36
+ - Extensibility for your own methods
37
+
