# 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](https://github.com/huggingface/datatrove)**, the same library employed in cleaning the **[FineWeb](https://huggingface.co/datasets/HuggingFaceFW/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

## Data Splits

- **Training Split:** 270,137 examples (620MB in size)

## How to Load the Dataset

To load the dataset using Hugging Face's `datasets` library:

```python
from datasets import load_dataset

dataset = load_dataset("saheedniyi/naijaweb")
```

## 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**.
