How It Was Built

All documents passed through language detection, quality filtering, PII redaction, and global deduplication before inclusion. See the source repository for the full pipeline code.

Quality Notes

• ~90% of volume is machine-translated encyclopedia content — more formal register than natural web text
• No detectable Bengali contamination (GlotLID asm_Beng vs ben_Beng)
• 87% document retention through all quality filters
