# OPUS PHP (ru-en) Parallel Corpora

The dataset contains parallel corpora, featuring pairs in Russian and English.

Initially, the original [OPUS PHP v1 (en&ru)](https://opus.nlpl.eu/PHP/en&ru/v1/PHP) dataset was intended to be used for training the [enbeddrus](https://github.com/EvilFreelancer/enbeddrus) project. However, due to its poor quality and high level of noise, it was decided to use only the English corpus from this dataset. The English text was then automatically translated using [LibreTranslate](https://libretranslate.com/), followed by manual translation and quality improvement using [Google Translate](https://translate.google.ru/).

Thus, the entire dataset was reviewed by the author of this project.

Subsequently, all lines shorter than 15 characters were removed, and lines such as "Example 1. function_name()" were manually deleted. Additionally, all duplicate lines, such as untranslated code samples, were removed. As a result, the original OPUS PHP v1 dataset was reduced from ~2k lines to ~1.6k lines.
