What it does

OpusCleaner is a web interface that helps you select, clean, and schedule your data for training machine translation models.

When to use it

•You need to preprocess large datasets for machine translation models
•Your data contains noise or inconsistent formatting that affects model performance
•You want to automate the data cleaning and scheduling process for your machine translation workflow

Ready-to-paste prompt

To clean a dataset named 'example.csv', use the following command in the OpusCleaner web interface: `opuscleaner clean example.csv --output cleaned_example.csv`

Heads up: Make sure you have Docker and Docker Compose installed on your system, as OpusCleaner relies on these to run the web interface and process data
