|
This parallel corpus was collected from several studies, assignments, and thesis of |
|
students of the Informatics Study Program, Tanjungpura University. Some of the corpus |
|
are used in the translation machine from Indonesian to local languages http://nustor.untan.ac.id/cammane/. |
|
This corpus can be used freely for research purposes by citing the paper |
|
https://ijece.iaescore.com/index.php/IJECE/article/download/20046/13738. |
|
|
|
The dataset is a combination of multiple machine translation works from the author, |
|
Herry Sujaini, covering Indonesian to 25 local dialects in Indonesia. Since not all |
|
dialects have ISO639-3 standard coding, as agreed with Pak Herry , we decided to |
|
group the dataset into the closest language family, i.e.: Javanese, Dayak, Buginese, |
|
Sundanese, Madurese, Banjar, Batak Toba, Khek, Malay, Minangkabau, and Tiociu. |
