Assamese Wikipedia Corpus

Dataset Description

The Assamese Wikipedia Corpus is a pure Assamese text dataset derived from the Assamese-language Wikipedia (as.wikipedia.org). It contains cleaned plain text extracted from Wikipedia articles, stripped of all formatting, with non-Assamese characters completely removed. This dataset is designed for language modeling, NLP research, creating Assamese specific tokenizers, and other Assamese-language processing tasks.

Data Processing

1. Crawling

• Used the mwclient Python library to interact with Wikipedia’s API.
• Only collected content from the main namespace (namespace=0).
• Pages that were redirects were automatically resolved to their target articles.
• Page titles were tracked to avoid processing the same article multiple times.
• Used mwparserfromhell to strip all MediaWiki formatting (links, templates, etc.).

2. Filtering

• Applied a Unicode regex to keep only Assamese characters (U+0980–U+09FF), Assamese digits, whitespace, and essential punctuation.
• Excluded pages where more than 90% of the content was punctuation or whitespace after cleaning.
• Removed very short pages that contained too little meaningful text.

Dataset Format

The dataset is provided as a .jsonl (JSON Lines) file, with each line containing:

{"text": "অসমীয়া উইকিপিডিয়াৰ এটি প্ৰবন্ধৰ উদাহৰণ ..."}

Example Usage

from datasets import load_dataset

# Load the dataset
dataset = load_dataset("marsh-mellow/assamese_wikipedia")
# Access the first example
print(dataset["train"][0]["text"])
