Data augmentation English-Indonesia-Madurese parallel corpus dataset using neural machine translation

INMAD is a dataset containing a corpus of English-Indonesian-Madurese translated sentences. This corpus stores a list of 23086 lines of sentences, as well as their translations in Indonesian and English. The details of each Madurese translation cover 1 language level, namely the 'engghi-enten' level. The framework for creating the dataset consists of two stages.

INMAD received validation from a Madurese language specialist, who also served as the translator for the source of this dataset. Consequently, this dataset can serve as the primary resource for Natural Language Processing (NLP) research, particularly for Madurese at the 'engghi-enten' level.
