AfriSenti-SemEval Shared Task 12 of SemEval-2023. The task aims to perform monolingual sentiment classification (sub-task A) for 12 African languages, multilingual sentiment classification (sub-task B), and zero-shot sentiment classification (task C). For sub-task A, we conducted experiments using classical machine learning classifiers, Afro-centric language models, and language-specific models. For task B, we fine-tuned multilingual pre-trained language models that support many of the languages in the task. For task C, we used we make use of a parameter-efficient Adapter approach that leverages monolingual texts in the target language for effective zero-shot transfer. Our findings suggest that using pre-trained Afro-centric language models improves performance for low-resource African languages. We also ran experiments using adapters for zero-shot tasks, and the results suggest that we can obtain promising results by using adapters with a limited amount of resources.

AfriSenti-SemEval 分享任务 12 旨在对 12 种非洲语言进行单语情感分类（子任务 A）、多语种情感分类（子任务 B）和零样本情感分类（任务 C）的分类。我们的实验表明，使用预训练的非洲语言模型可以提高非洲语言的低资源性能，而使用适配器进行零样本任务的实验结果表明，我们能够在有限的资源下通过使用适配器获得有希望的结果。
