## Dataset Creation

### Curation Rationale

There is a shortage of NLP research and resources for the Indonesian languages, despite the country having over 700 languages. With this in mind, we have created this dataset to support future research for the underrepresented languages in Indonesia.

### Source Data

#### Initial Data Collection and Normalization

NusaX-MT is a dataset for machine translation in Indonesian langauges that has been expertly translated by native speakers.

#### Who are the source language producers?

The data was produced by humans (native speakers).

### Annotations

#### Annotation process

NusaX-MT is derived from SmSA, which is the biggest publicly available dataset for Indonesian sentiment analysis. It comprises of comments and reviews from multiple online platforms. To ensure the quality of our dataset, we have filtered it by removing any abusive language and personally identifying information by manually reviewing all sentences. To ensure balance in the label distribution, we randomly picked 1,000 samples through stratified sampling and then translated them to the corresponding languages.

#### Who are the annotators?

Native speakers of both Indonesian and the corresponding languages.
Annotators were compensated based on the number of translated samples.

### Personal and Sensitive Information

Personal information is removed.

## Considerations for Using the Data

### Social Impact of Dataset

[More Information Needed](https://github.com/huggingface/datasets/blob/master/CONTRIBUTING.md#how-to-contribute-to-the-dataset-cards)

### Discussion of Biases

NusaX is created from review text. These data sources may contain some bias.

### Other Known Limitations

No other known limitations
