Access to open source language data can be difficult to find, especially text data in multiple languages. For those in search of Vietnamese text data, this article introduces ten Vietnamese datasets for machine learning.
The following list includes Vietnamese parallel text datasets, semantic datasets, and lexicons. They can be used for training machine translation models and sentiment analysis models, among other AI applications.
