## Dataset Description

- **Homepage:** https://www.zhengyinhe.com/datasets/
- **Repository:** https://github.com/silverriver/MMChat
- **Paper:** https://arxiv.org/abs/2108.07154

### Dataset Summary

MMChat is a large-scale dialogue dataset that contains image-grounded dialogues in Chinese. Each dialogue in MMChat is associated with one or more images (maximum 9 images per dialogue). We design various strategies to ensure the quality of the dialogues in MMChat.

MMChat comes with 4 different versions: 

- `mmchat`: The MMChat dataset used in our paper.
- `mmchat_hf`: Contains human annotation on 100K sessions of dialogues. 
- `mmchat_raw`: Raw dialogues used to construct MMChat.
  `mmchat_lccc_filtered`: Raw dialogues filtered using the LCCC dataset.

If you what to use high quality multi-modal dialogues that are closed related to the given images, I suggest you to use the `mmchat_hf` version.
If you only care about the quality of dialogue texts, I suggest you to use the `mmchat_lccc_filtered` version.

### Supported Tasks and Leaderboards

- dialogue-generation: The dataset can be used to train a model for generating dialogue responses.
- response-retrieval: The dataset can be used to train a reranker model that can be used to implement a retrieval-based dialogue model.

### Languages

MMChat is in Chinese

MMChat中的对话是中文的

## Dataset Structure

### Data Instances

Several versions of MMChat are available. For `mmchat`, `mmchat_raw`, `mmchat_lccc_filtered`, the following instance applies:

```json
{
  "dialog": ["你只拍出了你十分之一的美", "你的头像竟然换了，奥"],
  "weibo_content": "分享图片",
  "imgs": ["https://wx4.sinaimg.cn/mw2048/d716a6e2ly1fmug2w2l9qj21o02yox6p.jpg"]
}
```

For `mmchat_hf`, the following instance applies:

```json
{
  "dialog": ["白百合", "啊？", "有点像", "还好吧哈哈哈牙像", "有男盆友没呢", "还没", "和你说话呢。没回我"],
  "weibo_content": "补一张昨天礼仪的照片",
  "imgs": ["https://ww2.sinaimg.cn/mw2048/005Co9wdjw1eyoz7ib9n5j307w0bu3z5.jpg"],
  "labels": {
    "image_qualified": true, 
    "dialog_qualified": true, 
    "dialog_image_related": true
  }
}
```

### Data Fields

- `dialog` (list of strings): List of utterances consisting of a dialogue.
- `weibo_content` (string): Weibo content of the dialogue.
- `imgs` (list of strings): List of URLs of images.
- `labels` (dict): Human-annotated labels of the dialogue.
- `image_qualified` (bool): Whether the image is of high quality.
- `dialog_qualified` (bool): Whether the dialogue is of high quality.
- `dialog_image_related` (bool): Whether the dialogue is related to the image.

### Data Splits

For `mmchat`, we provide the following splits:

|train|valid|test|
|---:|---:|---:|
|115,842 | 4,000 | 1,000 |

For other versions, we do not provide the offical split.
