AI Low-Resource Language Models for African Indigenous Languages: Bridging the Digital Divide Through Innovative AI Natural Language Processing Solutions.
Authors/Creators
Description
This research investigates the development and optimization of natural language processing (NLP) models for African indigenous languages, addressing the critical digital divide that affects over 2 billion speakers across the continent. Through a comprehensive analysis of existing pre-trained language models and novel methodologies, this study examines the effectiveness of transformer-based architectures, specifically focusing on multilingual BERT variants, sentiment analysis systems, and speech recognition models for low-resource African languages. The research employs a design thinking framework to develop scalable solutions that enhance digital inclusion and educational accessibility. Our findings demonstrate that ensemble methods combining multiple pre-trained language models achieve superior performance, with weighted F1 scores exceeding 77% for closely related language families. The study contributes to the growing body of work in Afrocentric NLP by providing empirical evidence for effective cross-linguistic transfer learning techniques and proposing a framework for sustainable language model development in resource-constrained environments
