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.

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 Wikisource is a digital library of free-content textual sources, which includes historical documents, classical literature, legal texts, and poems that have been proofread by the community.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.
