# DatarrX MyWikisource Corpus

A high-quality, large-scale Burmese (Myanmar) language dataset extracted and refined from the official **Burmese Wikisource**. This dataset is specifically designed for Natural Language Processing (NLP) tasks, including language modeling, spell checking, and formal text analysis.

## Dataset Summary
- **Organization:** [DatarrX](https://huggingface.co/DatarrX)
- **Maintainer:** [Khant Sint Heinn(Kalix Louis)](https://huggingface.co/kalixlouiis)
- **Source:** [Burmese Wikisource (my.wikisource.org)](https://my.wikisource.org/)
- **Total Rows:** 1,352,972
- **Total Rows:** 1,352,972
- **Format:** ID, Categories, Title, Context
- **Language:** Burmese (Myanmar) - 100% (Threshold Filtered)
- **License:** MIT
  
## Data Origin (Source)
The data is sourced directly from the **Wikimedia Foundation's Wikisource project for the Burmese language**. Wikisource is a digital library of free-content textual sources, which includes historical documents, classical literature, legal texts, and poems that have been proofread by the community.

## Data Processing Details
This dataset has undergone rigorous cleaning to ensure high utility for AI/ML applications:

1.  **Namespace Filtering:** Only core encyclopedia/document entries (NS:0) were included, removing metadata and talk pages.
2.  **HTML/XML Cleaning:** All residual tags (e.g., `<p>`, `<div>`, etc.) have been removed using regex patterns.
3.  **Language Threshold:** A strict 70% Burmese character threshold was applied to every row to filter out heavy English or foreign language noise.
4.  **Deduplication:** Repeated contexts and duplicate entries were removed to prevent model overfitting.
5.  **Sentence Refinement:** - Sentences are split based on the Burmese period (။).
    - Extremely short fragments (less than 10 characters) were intelligently merged with adjacent sentences to maintain contextual meaning.
6.  **Noise Mitigation:** Known noise patterns like "မေး။ ။" and "ဖြေ။ ။" have been stripped out. 

> **Note:** While significant efforts were made to clean the data, users might still encounter minor noise due to the nature of historical transcriptions in the source material.
