Automating question generation and marking of language learning exercises for isiZulu

Increase in isiZulu language learning is hampered by the predominantly manual approach to creating and marking homework and test exercises. Extant computer-assisted language learning platforms cannot handle the intricacies of agglutination in isiZulu and related languages. We seek to address this by designing a controlled natural language-based exercise generator and marker for isiZulu. This consists of question and answer sentence templates for exercise types, reusable algorithm snippets as grammar library, a small corpus of words and sentences to be used by the system, a constrained sentence generator to combine the right type of words, and finally the exercise creation and automated marking system. The preliminary evaluation shows encouraging results

Natural Language Generation Requirements for Social Robots in Sub-Saharan Africa

Robots are deployed in Africa mainly in manufacturing, yet they may assist in society as future oriented technologies as well. They may ameliorate, e.g., service delivery issues and skills shortages. In this discussion paper, several uses and use cases relevant to Sub-Saharan Africa are described and requirements identified. We zoom in on human-robot interaction in Niger-Congo B (‘bantu’) languages. Use cases for healthcare and education elucidate specific requirements for the natural language generation component of robots in society. In contrast to typical generation systems, it demands i) combining data-to-text and knowledge-to-text in one system, ii) generating different types of sentences so as to switch between written and spoken language, and iii) processing non-trivial numbers
