VLSP2023-MT/ViBidirectionMT-Eval

These 2 Datasets are from VLSP Evaluation Campaigns for Machine Translation Shared Task

1) VLSP 2022 Dataset

Task Description:

• Machine Translation Shared Task:
  Chinese-Vietnamese Machine Translations (Chinese ↔ Vietnamese): The participants need to handle a scenario with limited data. Furthermore, since Chinese and Vietnamese can be considered similar languages to some degree (e.g., many Sino-Vietnamese words have a 1-to-1 mapping in meaning with their Chinese counterparts), participants could employ unique methods designed for similar language pairs in this task.

Bilingual Training and Evaluation Corpora Statistics:

2) VLSP 2023 Dataset

Task Description:

• Machine Translation Shared Task:
  The 2023 shared task introduced two sub-tasks on Lao-Vietnamese Machine Translations (Lao ↔ Vietnamese). As in previous years, participants dealt with a scenario of limited data. Lao and Vietnamese share similarities (e.g., many Vietnamese words have a 1-to-1 mapping in meaning with their Lao counterparts), enabling participants to apply innovative methods for similar language pairs in this task.

Bilingual Training and Evaluation Corpora Statistics:

Task	Dataset	Sentences	Tokens (Vi)	Tokens (Lo)
Vi ↔ Lo	Train	100,000	2,850,755	4,070,248
	Dev	1,000	52,821	72,789
	Test	1,000	32,386	49,175
