Dataset Card for Asian Language Treebank (ALT)

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 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.

Data Fields

ALT Parallel Corpus

• SNT.URLID: URL link to the source article listed in 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 for more detail.

Dataset Creation

Curation Rationale

The ALT project was initiated by the National Institute of Information and Communications Technology, Japan (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.
