From Data Engineering to Natural Language Corpora - The DSFSI 2022/2023 Summer Internship
Richard Lastrucci and Isheanesu Dzingirai - The main focus was collection, processing and creation of parallel corpora in the 11 official languages of South Africa. We collected multilingual data by building web scrapers, we processed and cleaned this and other extracted data before performing sentence alignment to produce the parallel corpora. We also improved and documented Masakhane Web.

DSFSI Summer Research Experience: Fine-tuning Multilingual Pre-trained African Language Models
Rozina Myoya and Fiskani Banda - The aim of the research was to explore the application of Pre-trained Language Models(PLMs) on a multilingual classification task. The study concluded that PLMs perform best on downstream tasks on the languages they were pre-trained on, thus emphasising the importance of including low resource languages in the pre-training process of LMs.
