From Text Segmentation to Smart Chaptering: A Novel Benchmark for Structuring Video Transcriptions

We present YTSeg, a topically and structurally diverse benchmark for the text segmentation task based on YouTube transcriptions. The dataset comprises 19,299 videos from 393 channels, amounting to 6,533 content hours. The topics are wide-ranging, covering domains such as science, lifestyle, politics, health, economy, and technology. The videos are from various types of content formats, such as podcasts, lectures, news, corporate events & promotional content, and, more broadly, videos from individual content creators. We refer to the paper for further information.

Data Overview

YTSeg

Each video is represented as a JSON object with the following fields:

Field	Description
`text`	A flat list of sentences.
`targets`	The target segmentation as string of binary values (e.g., `000100000010`).
`channel_id`	The YouTube channel ID which this video belongs to.
`video_id`	The YouTube video ID.

Partition	# Examples
Training	16,404 (85%)
Validation	1,447 (7.5%)
Testing	1,448 (7.5%)
Total	19,229

YTSeg[Titles]

Each chapter of a video is represented as a JSON object with the following fields:

Field	Description
`input`	The complete chapter/section text.
`input_with_chapters`	The complete chapter/section text with previous section titles prepended.
`target`	The target chapter title.
`channel_id`	The YouTube channel ID which this chapter's video belongs to.
`video_id`	The YouTube video ID which this chapter belongs to.
`chapter_idx`	The index and placement of the chapter in the video (e.g., the first chapter has index `0`).

Partition	# Examples
Training	146,907 (84.8%)
Validation	13,206 (7.6%)
Testing	13,082 (7.6%)
Total	173,195

Video & Audio Data

A download script for the video and audio data is provided.

python download_videos.py

In the script, you can further specify a target folder (default is ./video) and target formats in a priority list.

Loading Data

This repository comes with a simple, exemplary script to read in the data with pandas.

from load_data import get_partition
test_data = get_partition('test')

Equivalently, to read in YTSeg[Titles]:

from load_data import get_title_partition
test_data = get_title_partition('test')

    abstract = "Text segmentation is a fundamental task in natural language processing, where documents are split into contiguous sections. However, prior research in this area has been constrained by limited datasets, which are either small in scale, synthesized, or only contain well-structured documents. In this paper, we address these limitations by introducing a novel benchmark YTSeg focusing on spoken content that is inherently more unstructured and both topically and structurally diverse. As part of this work, we introduce an efficient hierarchical segmentation model MiniSeg, that outperforms state-of-the-art baselines. Lastly, we expand the notion of text segmentation to a more practical {``}smart chaptering{''} task that involves the segmentation of unstructured content, the generation of meaningful segment titles, and a potential real-time application of the models.",
