### Dataset Summary
The ALT project aims to advance the state-of-the-art Asian natural language processing (NLP) techniques through the open collaboration for developing and using ALT. It was first conducted by NICT and UCSY as described in Ye Kyaw Thu, Win Pa Pa, Masao Utiyama, Andrew Finch and Eiichiro Sumita (2016). Then, it was developed under [ASEAN IVO](https://www.nict.go.jp/en/asean_ivo/index.html) as described in this Web page.
The process of building ALT began with sampling about 20,000 sentences from English Wikinews, and then these sentences were translated into the other languages.
### Supported Tasks and Leaderboards
Machine Translation, Dependency Parsing
### Languages
It supports 13 language:
* Bengali
* English
* Filipino
* Hindi
* Bahasa Indonesia
* Japanese
* Khmer
* Lao
* Malay
* Myanmar (Burmese)
* Thai
* Vietnamese
* Chinese (Simplified Chinese).

### Data Fields
#### ALT Parallel Corpus
- SNT.URLID: URL link to the source article listed in [URL.txt](https://www2.nict.go.jp/astrec-att/member/mutiyama/ALT/ALT-Parallel-Corpus-20191206/URL.txt)
- SNT.URLID.SNTID: index number from 1 to 20000. It is a seletected sentence from `SNT.URLID`
and bg, en, fil, hi, id, ja, khm, lo, ms, my, th, vi, zh correspond to the target language
#### ALT Treebank
- status: it indicates how a sentence is annotated; `draft` sentences are annotated by one annotater and `reviewed` sentences are annotated by two annotater
The annotatation is different from language to language, please see [their guildlines](https://www2.nict.go.jp/astrec-att/member/mutiyama/ALT/) for more detail.

## Dataset Creation
### Curation Rationale
The ALT project was initiated by the [National Institute of Information and Communications Technology, Japan](https://www.nict.go.jp/en/) (NICT) in 2014. NICT started to build Japanese and English ALT and worked with the University of Computer Studies, Yangon, Myanmar (UCSY) to build Myanmar ALT in 2014. Then, the Badan Pengkajian dan Penerapan Teknologi, Indonesia (BPPT), the Institute for Infocomm Research, Singapore (I2R), the Institute of Information Technology, Vietnam (IOIT), and the National Institute of Posts, Telecoms and ICT, Cambodia (NIPTICT) joined to make ALT for Indonesian, Malay, Vietnamese, and Khmer in 2015.
### Source Data
#### Initial Data Collection and Normalization

#### Who are the source language producers?
The dataset is sampled from the English Wikinews in 2014. These will be annotated with word segmentation, POS tags, and syntax information, in addition to the word alignment information by linguistic experts from
* National Institute of Information and Communications Technology, Japan (NICT) for Japanses and English
* University of Computer Studies, Yangon, Myanmar (UCSY) for Myanmar
* the Badan Pengkajian dan Penerapan Teknologi, Indonesia (BPPT) for Indonesian
* the Institute for Infocomm Research, Singapore (I2R) for Malay
* the Institute of Information Technology, Vietnam (IOIT) for Vietnamese
* the National Institute of Posts, Telecoms and ICT, Cambodia for Khmer
