We provide a multimodal large-scale video dataset based on nonverbal communication.

Please cite our work if you find our data helpful.

Our dataset collection pipeline and the model implementation that uses it are available at <a href='https://github.com/winston1214/nonverbal-conversation'>https://github.com/winston1214/nonverbal-conversation</a>

### Data Structure

Here's an overview of our dataset structure:

```
{
    'channel_id': str,  # YouTube channel ID
    'video_id': str,  # Video ID
    'segment_id': int,  # Segment ID within the video
    'duration': str,  # Total segment duration (e.g., '00:11:00 ~ 00:21:00')
    'fps': int,  # Frames per second

    'conversation': [  # Conversation information (consisting of multiple utterances)
        {
            'utterance_id': int,  # Utterance ID
            'speaker': int,  # Speaker ID (represented as an integer)
            'text': str,  # Full utterance text
            'start_time': float,  # Start time of the utterance (in seconds)
            'end_time': float,  # End time of the utterance (in seconds)
            'words': [  # Word-level information
                {
                    'word': str,  # The word itself
                    'start_time': float,  # Word-level start time
                    'end_time': float,  # Word-level end time
                }
            ]
        }
    ],

    'facial_expression': [  # Facial expression features
        {
            'utt_id': int,  # ID of the utterance this expression is aligned to
            'frame': int,  # Frame identifier
            'features': [float],  # Facial feature vector (153-dimensional)
        }
    ],

    'body_language': [  # Body language features

### Data Splits

Data splits can be accessed as:
```python
from datasets import load_dataset
train_dataset = load_dataset("winston1214/VENUS-10K", split = "train")
test_dataset = load_dataset("winston1214/VENUS-10K", split = "test")
```

### Curation Rationale

Full details are in the paper.

### Source Data
We retrieve natural videos from YouTube and annotate the FLAME and SMPL-X parameters from EMOCAv2 and OSX.

### Initial Data Collection
Full details are in the paper.

### Annotations

Full details are in the paper.

### Annotation Process

Full details are in the paper.

### Who are the annotators?

We used an automatic annotation method, and the primary annotator was Youngmin Kim, the first author of the paper.

### Considerations for Using the Data

This dataset (VENUS) consists of 3D annotations of human subjects and text extracted from conversations in the videos.
Please note that the dialogues are sourced from online videos and may include informal or culturally nuanced expressions.
Use of this dataset should be done with care, especially in applications involving human-facing interactions.
