 ## Data Overview
 
-### <span style="font-variant:small-caps;">YTSeg</span>
+We offer three dataset subsets:
+- **Text** — For text-based segmentation and chaptering approaches using transcripts.
+- **Audio** — For audio-based chaptering approaches with embedded audio.
+- **Titles** — For chapter title generation given segment text (relevant for two-stage approaches).
 
-Each video is represented as a JSON object with the following fields:
+### <span style="font-variant:small-caps;">YTSeg</span> (Text)
 
+Each video is represented as a JSON object. The fields are organized into three categories: **Transcripts**, **Target Representations**, and **Metadata**.
 
-| 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.            |
-| `audio_path` | Path to the .mp3 file of the video            |
-| `chapters`   | A list of chapter titles corresponding to each segment |
+#### Transcripts
+
+We provide three transcript variants for each video: the original reference transcript and two ASR-generated transcripts using Whisper models.
+
+| Field  | Description |
+|--------|-------------|
+| `text_ref` | Reference transcript as a flat list of sentences. |
+| `text_wt` | Whisper-tiny ASR transcript as a flat list of sentences. |
+| `text_wl` | Whisper-large ASR transcript as a flat list of sentences. |
+
+#### Target Representations
+
+Multiple target formats are provided for different modeling approaches.
+
+| Field  | Description |
+|--------|-------------|
+| `target_binary_ref` | Binary segmentation labels for reference transcript (e.g., `\|=000100000010`). |
+| `target_binary_wt` | Binary segmentation labels for Whisper-tiny transcript. |
+| `target_binary_wl` | Binary segmentation labels for Whisper-large transcript. |
+| `target_text_ref` | Structured transcript with chapter markers (e.g., `[CSTART] Title [CEND] text...`). |
+| `target_text_ts_ref` | Structured transcript with timestamped chapter markers (e.g., `[CSTART] 00:01:23 - Title [CEND] text...`). |
+| `target_ts` | Timestamped chapter markers only (e.g., `[CSTART] 00:01:23 - Title [CEND]\n...`). |
+
+#### Metadata
+
+| Field  | Description |
+|--------|-------------|
+| `audio_path` | Path to the .mp3 file of the video. |
+| `chapter_titles` | A list of chapter titles corresponding to each segment. |
+| `channel_id` | The YouTube channel ID which this video belongs to. |
+| `video_id` | The YouTube video ID. |
+| `speaker_category` | Speaker classification: `single`, `single_weak`, or `multiple`. |
+| `dominant_speaker_proportion` | Proportion of speech from the dominant speaker (0.0-1.0). |
+| `num_speakers` | Number of detected speakers in the video. |
+| `duration` | Video duration in seconds. |
