    abstract = "Africa is home to over 2,000 languages from over six language families and has the highest linguistic diversity among all continents. This includes 75 languages with at least one million speakers each. Yet, there is little NLP research conducted on African languages. Crucial in enabling such research is the availability of high-quality annotated datasets. In this paper, we introduce AfriSenti, a sentiment analysis benchmark that contains a total of {\textgreater}110,000 tweets in 14 African languages (Amharic, Algerian Arabic, Hausa, Igbo, Kinyarwanda, Moroccan Arabic, Mozambican Portuguese, Nigerian Pidgin, Oromo, Swahili, Tigrinya, Twi, Xitsonga, and Yoruba) from four language families. The tweets were annotated by native speakers and used in the AfriSenti-SemEval shared task (with over 200 participants, see website: https://afrisenti-semeval.github.io). We describe the data collection methodology, annotation process, and the challenges we dealt with when curating each dataset. We further report baseline experiments conducted on the AfriSenti datasets and discuss their usefulness.",

AfriSenti-SemEval 2023 Shared Task

We provide the training, dev and test set for each task below.

Sample Tweets and Distribution

Sentiment Lexicon

We provide sentiment lexicon in some languages that may be useful for the task.

Baselines

See example here

Shared Task Starter kit

We provide a starter kit for the competition to create a baseline result. You can open the starter kit in Colab Notebook and run the baseline system. The resultant experiment can be submitted to codalab to ensure all submission format is clear. You can then work on your own system towards the competition.

To run the Colab Notebook, fork this repo first and click the badge "open on colab" on the forked version.

  • Task A: Open In Colab
  • Task B: Open In Colab
