NusaX is a high-quality multilingual parallel corpus that covers 12 languages, Indonesian, English, and 10 Indonesian local languages, namely Acehnese, Balinese, Banjarese, Buginese, Madurese, Minangkabau, Javanese, Ngaju, Sundanese, and Toba Batak.

NusaX is created by translating existing sentiment analysis dataset into local languages. Our translations are written and verified by local native speakers. Therefore, NusaX can be broken down into 2 separate tasks:

• NusaX-MT: Machine Translation task
• NusaX-Senti: Sentiment Analysis task

Additionally, we also release the NusaX-Lexicon, which consists of parallel, sentiment lexicon of 10 Indonesian local languages.
