+# 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:
+
+```json
+{"text": "অসমীয়া উইকিপিডিয়াৰ এটি প্ৰবন্ধৰ উদাহৰণ ..."}
+```
+
+## Example Usage
+
+```python
+from datasets import load_dataset
+
+# Load the dataset
+dataset = load_dataset("marsh-mellow/assamese_wikipedia")
+# Access the first example
+print(dataset["train"][0]["text"])
+```
