# ResponseNet

**ResponseNet** is a large-scale dyadic video dataset designed for **Online Multimodal Conversational Response Generation (OMCRG)**. It fills the gap left by existing datasets by providing high-resolution, split-screen recordings of both speaker and listener, separate audio channels, and word‑level textual annotations for both participants.

## Features

- **696** temporally synchronized dyadic video pairs (over **14 hours** total).
- **High-resolution** (1024×1024) frontal‑face streams for both speaker and listener.
- **Separate audio channels** for fine‑grained verbal and nonverbal analysis.
- **Word‑level textual annotations** for both participants.
- **Longer clips** (average **73.39 s**) than REACT2024 (30 s) and Vico (9 s), capturing richer conversational exchanges.
- **Diverse topics**: professional discussions, emotionally driven interactions, educational settings, interdisciplinary expert talks.
- **Balanced splits**: training, validation, and test sets with equal distributions of topics, speaker identities, and recording conditions.

## Data Fields

Each example in the dataset is a dictionary with the following fields:

- `video/speaker`: Path to the speaker’s video stream (1024×1024, frontal view).
- `video/listener`: Path to the listener’s video stream (1024×1024, frontal view).
- `audio_speaker`: Path to the speaker’s separated audio channel.
- `audio/listener`: Path to the listener’s separated audio channel.
- `transcript/speaker`: Word‑level transcription for the speaker (timestamps included).
- `transcript/listener`: Word‑level transcription for the listener (timestamps included).
- `vector/speaker`: Path to the speaker’s facial attributes.
- `vector/listener`: Path to the listener’s facial attributes.

## Dataset Splits

We follow a standard **6:2:2** split ratio, ensuring balanced distributions of topics, identities, and recording conditions:

| Split      | # Video Pairs | Proportion (%) |
|------------|---------------|----------------|
| **Train**  | 417           | 59.9           |
| **Valid**  | 139           | 20.0           |
| **Test**   | 140           | 20.1           |
| **Total**  | 696           | 100.0          |



## Visualization

You can visualize word‑cloud statistics, clip‑duration distributions, and topic breakdowns using standard Python plotting tools.
