Naijaweb Dataset

Naijaweb is a dataset that contains over 270,000+ documents, totaling approximately 230 million GPT-2 tokens. The data was web scraped from web pages popular among Nigerians, providing a rich resource for modeling Nigerian linguistic and cultural contexts.

Dataset Summary

Features	Data Types
Unnamed: 0	int64
text	string
id	string
link	string
token_count	int64
section	string
domain	string
score	float64
int_score	int64
language	string
language_probability	float64

Data Collection

The dataset was collected from Nairaland.com, extracting 1,795,908 unique posts from 19 different sections of the site. Additionally, 1,289,195 outbound links were extracted from these posts. The content of these web pages was extracted using Trafilatura, a popular library for web scraping and content extraction.

Data Cleaning

The cleaning process was conducted using Datatrove, the same library employed in cleaning the FineWeb dataset, which is known for its high quality. The data cleaning process involved multiple stages of deduplication, filtering, and normalization to ensure the dataset's quality matches that of other high-performing datasets.

Data Cleaning Procedure:

URL Filtering
Repitition and quality filtering:
Personal Identifiable Information (PII) Removal

Example Entry

Each data point contains the following fields:

Unnamed: 0: an index column
text: the main body of the post or web page
id: unique identifier for each document
link: the original URL of the source content
token_count: the number of tokens in the text field
section: the Nairaland section where the post was found
domain: the domain of the outbound link
score: a float representing the content's relevance or quality
int_score: an integer representation of score
language: detected language of the text (e.g., en, yo, ha, ig)
language_probability: the confidence score of the language detection algorithm

Social Impact

Naijaweb was created to make Nigerian web data more accessible, providing researchers and developers with a dataset rich in Nigerian contexts across various domains such as Politics, Education, Business, and Health.

Bias and Ethical Considerations

Since the data is collected from publicly available web pages, inherent biases present in the sources may be reflected in the dataset. These biases can manifest in areas such as language, ideology, or topic representation. Users should be mindful of these potential biases when developing models, especially for sensitive areas like legal or medical information.

Sections of the Dataset

The dataset comprises content from 19 different sections of Nairaland.com, covering topics such as Politics, Education, Business, and Health.
