Dataset Description

Dataset Summary

NaijaSenti is the first large-scale human-annotated Twitter sentiment dataset for the four most widely spoken languages in Nigeria — Hausa, Igbo, Nigerian-Pidgin, and Yorùbá — consisting of around 30,000 annotated tweets per language, including a significant fraction of code-mixed tweets.

Supported Tasks and Leaderboards

The NaijaSenti can be used for a wide range of sentiment analysis tasks in Nigerian 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. It was part of the datasets that were used for SemEval 2023 Task 12: Sentiment Analysis for African Languages.

Languages

4 most spoken Nigerian languages

  • Hausa (hau)
  • Igbo (ibo)
  • Nigerian Pidgin (pcm)
  • Yoruba (yor)

Dataset Structure

Data Instances

For each instance, there is a string for the tweet and a string for the label. See the NaijaSenti 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 NaijaSenti 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., Hausa). This download train, validation and test sets. 
ds = load_dataset("HausaNLP/NaijaSenti-Twitter", "hau")

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

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

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

Dataset Creation

Curation Rationale

NaijaSenti Version 1.0.0 aimed to be used sentiment analysis and other related task in Nigerian indigenous and creole languages - Hausa, Igbo, Nigerian Pidgin and Yoruba.

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