Dataset Description

Dataset Summary

AfriSenti is the largest sentiment analysis dataset for under-represented African languages, covering 110,000+ annotated tweets in 14 African languages (Amharic, Algerian Arabic, Hausa, Igbo, Kinyarwanda, Moroccan Arabic, Mozambican Portuguese, Nigerian Pidgin, Oromo, Swahili, Tigrinya, Twi, Xitsonga, and Yoruba).

The datasets are used in the first Afrocentric SemEval shared task, SemEval 2023 Task 12: Sentiment analysis for African languages (AfriSenti-SemEval). AfriSenti allows the research community to build sentiment analysis systems for various African languages and enables the study of sentiment and contemporary language use in African languages.

Supported Tasks and Leaderboards

The AfriSenti can be used for a wide range of sentiment analysis tasks in African languages, such as sentiment classification, sentiment intensity analysis, and emotion detection. This dataset is suitable for training and evaluating machine learning models for various NLP tasks related to sentiment analysis in African languages. SemEval 2023 Task 12 : Sentiment Analysis for African Languages

Languages

14 African languages (Amharic (amh), Algerian Arabic (ary), Hausa(hau), Igbo(ibo), Kinyarwanda(kin), Moroccan Arabic/Darija(arq), Mozambican Portuguese(por), Nigerian Pidgin (pcm), Oromo (oro), Swahili(swa), Tigrinya(tir), Twi(twi), Xitsonga(tso), and Yoruba(yor)).

Data Instances

For each instance, there is a string for the tweet and a string for the label. See the AfriSenti dataset viewer to explore more examples.

{
  "tweet": "string",
  "label": "string"
}

Data Fields

The data fields are:

tweet: a string feature.
label: a classification label, with possible values including positive, negative and neutral.

Data Splits

The AfriSenti dataset has 3 splits: train, validation, and test. Below are the statistics for Version 1.0.0 of the dataset.

How to use it

from  datasets  import  load_dataset

# you can load specific languages (e.g., Amharic). This download train, validation and test sets. 
ds = load_dataset("HausaNLP/AfriSenti-Twitter", "amh")

# train set only
ds = load_dataset("HausaNLP/AfriSenti-Twitter", "amh", split = "train")

# test set only
ds = load_dataset("HausaNLP/AfriSenti-Twitter", "amh", split = "test")

# validation set only
ds = load_dataset("HausaNLP/AfriSenti-Twitter", "amh", split = "validation")

Dataset Creation

Curation Rationale

AfriSenti Version 1.0.0 aimed to be used in the first Afrocentric SemEval shared task SemEval 2023 Task 12: Sentiment analysis for African languages (AfriSenti-SemEval).

Source Data

Twitter

Personal and Sensitive Information

We anonymized the tweets by replacing all @mentions by @user and removed all URLs.

Considerations for Using the Data

Social Impact of Dataset

The Afrisenti dataset has the potential to improve sentiment analysis for African languages, which is essential for understanding and analyzing the diverse perspectives of people in the African continent. This dataset can enable researchers and developers to create sentiment analysis models that are specific to African languages, which can be used to gain insights into the social, cultural, and political views of people in African countries. Furthermore, this dataset can help address the issue of underrepresentation of African languages in natural language processing, paving the way for more equitable and inclusive AI technologies.
