Connectionists: Call for Participation: SemEval-2023 Shared Task 12 - Sentiment Analysis for African Languages (AfriSenti-SemEval)

[Shamsuddeen Hassan Muhammad]

Dear Colleagues,

We are glad to invite you to participate in SemEval-2023 Shared Task 12, the first SemEval shared task for sentiment analysis targeting African low resource languages.
The AfriSenti-SemEval Shared Task 12 is based on a collection of humanly annotated Twitter datasets in 16 African languages (all low resource) for sentiment classification. This year, we have three sub-tasks, from which the participants can choose one or more tasks depending on their preference.

Task A: Monolingual Sentiment Classification

Given training data in a target language, determine the polarity of a tweet in the target language (positive, negative, or neutral). If a tweet conveys both a positive and negative sentiment, whichever is the stronger sentiment should be chosen. This sub-task covers 15 languages namely, Hausa, Yoruba, Igbo, Nigerian_Pidgin, Amharic, Algerian Arabic, Kinyarwanda, Twi, Mozambican Portuguese, Swahili, Setswana, isiZulu, Moroccan Arabic/Darija, Xitsonga (South-African Dialect), Xitsonga (Mozambique Dialect)

Task B: Multilingual Sentiment Classification

Given a combined training data from 12 African languages, determine the polarity of a tweet in the target language (positive, negative, or neutral).

Task C: Zero-Shot Sentiment Classification

Given unlabeled tweets in two African languages (Oromo, and Tigrinya), leverage any or all of the available training datasets in Subtasks A and B to determine the sentiment of a tweet in the two target languages is positive, negative, or neutral.
