This English-Luganda parallel sentence corpus was created by a team of researchers from AI & Data science research Lab at Makerere University with a team of Luganda teachers, students and freelancers. The collaborative work which involves generating English sentences under CC-0 and translating these sentences using a crowdsourcing, iterative and opensource approach was done using Pontoon an opensource Translation Management System built by Mozilla. Acknowledgment: This project was supported by the AI4D language dataset fellowship through K4All and Zindi Africa.
