Abstract

This paper describes our participation in Task 12: AfriSenti-SemEval 2023, i.e., Track 12 of subtask A, Track 16 of subtask B, and Track 18 of subtask C. To deal with these three tracks, we utilize Support Vector Machine (SVM) + One vs Rest, SVM + One vs Rest with SMOTE, and AfriBERTa-large models. In particular, our SVM + One vs Rest with SMOTE model could obtain the highest weighted F1-Score for Tracks 16 and 18 in the evaluation phase, that is, 65.14% and 33.49%, respectively. Meanwhile, our SVM + One vs Rest model could perform better than other models for Track 12 in the evaluation phase.
