Advancing African NLP: UDMorph and flexiPipe

AbstractIn this paper, we present some of our recent efforts to provide base NLP pipelines for African languages. These include an infrastructure called UDMorph to make UD-compatible training data available for resources that do not have dependency relations, and a Python package called flexiPipe to easily run an NLP pipeline in various NLP tools using a uniform front-end, including the models provided by UDMorph. flexiPipe also provides Unicode normalization, an often overlooked feature that has a significant impact on African NLP. flexiPipe currently provides an NLP pipeline for 33 African languages, a significant increase from the handful of models that are currently easily accessible. And UDMorph is designed to make it easy to provide training data for more languages.
