# IN22-Conv

IN-22 is a newly created comprehensive benchmark for evaluating machine translation performance in multi-domain, n-way parallel contexts across 22 Indic languages. IN22-Conv is the conversation domain subset of IN22. It is designed to assess translation quality in typical day-to-day conversational-style applications. The evaluation subset consists of 1024 sentences translated across 22 Indic languages enabling evaluation of MT systems across 506 directions.

Currently, we use it for sentence-level evaluation of MT systems but can be repurposed for document translation evaluation as well.

Here is the domain distribution of our IN22-Conv evaluation subset.

Please refer to the `Appendix E: Dataset Card` of the [preprint](https://arxiv.org/abs/2305.16307) on detailed description of dataset curation, annotation and quality control process.


### Dataset Structure

#### Dataset Fields

- `id`: Row number for the data entry, starting at 1.
- `doc_id`: Unique identifier of the conversation.
- `sent_id`: Unique identifier of the sentence order in each conversation.
- `topic`: The specific topic of the conversation within the domain.
- `domain`: The domain of the conversation.
- `prompt`: The prompt provided to annotators to simulate the conversation.
- `scenario`: The scenario or context in which the conversation takes place.
- `speaker`: The speaker identifier in the conversation.
- `turn`: The turn within the conversation.

#### Data Instances

A sample from the `gen` split for the English language (`eng_Latn` config) is provided below. All configurations have the same structure, and all sentences are aligned across configurations and splits.

```python
{
   "id": 1,
   "doc_id": 0,
   "sent_id": 1,
   "topic": "Festivities",
   "domain": "culture",
   "prompt": "14th April a holiday",
   "scenario": "Historical importance",
   "speaker": 1,
   "turn": 1,
   "sentence": "Mom, let's go for a movie tomorrow."
}
```

When using a hyphenated pairing or using the `all` function, data will be presented as follows:

```python
{
   "id": 1,
   "doc_id": 0,
   "sent_id": 1,
   "topic": "Festivities",
   "domain": "culture",
   "prompt": "14th April a holiday",
   "scenario": "Historical importance",
   "speaker": 1,
   "turn": 1,
   "sentence_eng_Latn": "Mom, let's go for a movie tomorrow.",
   "sentence_hin_Deva": "माँ, चलो कल एक फिल्म देखने चलते हैं।"
}
```

#### Sample Conversation

    <tr>
        <td>Speaker</td>
        <td>Turn</td>
    </tr>
    <tr>
        <td>Speaker 1</td>
        <td>Mom, let&#39;s go for a movie tomorrow. I don&#39;t have to go to school. It is a holiday.</td>
    </tr>
    <tr>
        <td>Speaker 2</td>
        <td>Oh, tomorrow is the 14th of April right? Your dad will also have the day off from work. We can make a movie plan!</td>
    </tr>
    <tr>
        <td>Speaker 1</td>
        <td>That&#39;s a good news! Why is it a holiday though? Are all schools, colleges and offices closed tomorrow?</td>
    </tr>
    <tr>
        <td>Speaker 2</td>
        <td>It is Ambedkar Jayanti tomorrow! This day is celebrated annually to mark the birth of Dr. B. R Ambedkar. Have you heard of him?</td>
    </tr>
    <tr>
        <td>Speaker 1</td>
        <td>I think I have seen him in my History and Civics book. Is he related to our Constitution?</td>
    </tr>
    <tr>
        <td>Speaker 2</td>
        <td>Absolutely! He is known as the father of the Indian Constitution. He was a civil rights activist who played a major role in formulating the Constitution. He played a crucial part in shaping the vibrant democratic structure that India prides itself upon.</td>
    </tr>
    <tr>
        <td></td>
        <td>...</td>
    </tr>
