TITLE: SIB-200: A Simple, Inclusive, and Big Evaluation Dataset for Topic Classification in 200+ Languages and Dialects 

ABSTRACT: Despite the progress we have recorded in the last few years in multilingual
natural language processing, evaluation is typically limited to a small set of
languages with available datasets which excludes a large number of low-resource
languages. In this paper, we created SIB-200 -- a large-scale open-sourced
benchmark dataset for topic classification in 200 languages and dialects to
address the lack of evaluation dataset for Natural Language Understanding
(NLU). For many of the languages covered in SIB-200, this is the first publicly
available evaluation dataset for NLU. The dataset is based on Flores-200
machine translation corpus. We annotated the English portion of the dataset and
extended the sentence-level annotation to the remaining 203 languages covered
in the corpus. Despite the simplicity of this task, our evaluation in
full-supervised setting, cross-lingual transfer setting and prompting of large
language model setting show that there is still a large gap between the
performance of high-resource and low-resource languages when multilingual
evaluation is scaled to numerous world languages. We found that languages
unseen during the pre-training of multilingual language models,
under-represented language families (like Nilotic and Altantic-Congo), and
languages from the regions of Africa, Americas, Oceania and South East Asia,
often have the lowest performance on our topic classification dataset. We hope
our dataset will encourage a more inclusive evaluation of multilingual language
models on a more diverse set of languages. https://github.com/dadelani/sib-200
