Myanmar Wikipedia Dataset (20260501)

This dataset contains a cleaned, processed, and high-quality collection of Burmese Wikipedia articles, curated to serve as a robust foundation for Natural Language Processing (NLP) and Artificial Intelligence development in the Burmese language.

🏛️ About DatarrX

DatarrX (Burmese: ဒေတာအက်စ်) is a non-profit open-source foundation dedicated to building a robust digital foundation for the Burmese language in the AI era. We believe that high-quality data is the core of AI innovation. Our mission is to empower the Burmese AI ecosystem by building high-quality open-source datasets, essential AI tools, and localized technical resources.

🏗️ Dataset Creation Pipeline

This dataset was developed through a rigorous multi-stage cleaning and preparation process to ensure maximum utility for researchers and developers:

Data Extraction: The source material was derived from the official Burmese Wikipedia Database Dump (2026-05-01).
Markup Sanitization: We systematically removed MediaWiki markup, HTML tags, template artifacts ({{...}}), and internal links ([[...]]).
Filtering & Noise Reduction: * Applied strict Zawgyi-to-Unicode verification to ensure data consistency.
- Removed tabular metadata, non-informative CSS/module snippets, and malformed rows.
- Filtered out rows containing non-Burmese characters (where applicable) and low-information symbols.
Sentence Segmentation & Normalization: * Articles were split into individual sentences.
- We enforced a standard Burmese full-stop (။) at the end of every sentence to ensure structural consistency.
Syllable Tokenization: Using mm-syllable, every sentence was segmented into its constituent Burmese syllables, providing a secondary column (syllable) for syllable-level model training.

📊 Dataset Statistics

Total Sentences: 546,045
Average Sentence Length: 122.98 characters
Average Syllable Count: 39.11
Structural Consistency: 99.90% of sentences end with the standard Burmese full-stop (။).

Data Structure

Column	Description
`text`	The clean, normalized Burmese sentence.
`syllable`	The same sentence segmented into syllables with spaces.
