Fixing OCR addresses

Sat, 05 Jul 2025 00:00:00 +0000

OCR on government documents works well until you look at the address fields.

State: "DKI JAKRTA"
City: "JAKRTA PUSAT"
District: "MENTNG"
Village: "MENTENG"

Dropped vowels, character substitutions, truncated names. Indonesian place names get mangled in predictable ways – ‘A’ becomes ‘R’, characters vanish mid-word. The OCR engine reads the image fine. It just can’t spell.

The problem: take these broken strings and map them back to real administrative divisions. Province, city, district, village – the hierarchy matters, and every level needs to resolve correctly.
