Build-time resources for myspellchecker - Myanmar language spell checker.
Overview
This repository hosts large binary files required by myspellchecker that are too large to bundle with the Python package. Files are downloaded automatically on first use.
Contents
segmentation/
- segmentation.mmap (100MB) - Memory-mapped dictionary containing unigram and bigram log probabilities for Myanmar word segmentation using Viterbi algorithm.
models/
- wordseg_c2_crf.crfsuite (3.2MB) - Conditional Random Fields model for syllable-based word tokenization.
curated_lexicon/
- curated_lexicon.csv - Curated Myanmar word list with POS tags for spell checking (57,566 entries).
This lexicon is built from the Myanmar Words List and the Ornagai dictionary. Data from the Ornagai dictionary was filtered and cleaned to produce a high-quality, consistent word list suitable for spell checking.

Technical Notes
.bin to .mmap Conversion
The segmentation dictionary has been converted from pickle-based .bin files to memory-mapped .mmap format for:
- Memory Efficiency - Lazy loading without loading entire file into RAM
- Fork-Safe - Copy-on-Write (COW) semantics for multiprocessing
- Faster Startup - No pickle deserialization overhead
- Security - Eliminates pickle arbitrary code execution vulnerabilities
- Reduced Size - 100MB consolidated vs 315MB separate .bin files
