Overview
libpostal is a C library for parsing and normalizing street addresses from around the world. It uses statistical NLP trained on open data, with the goal of understanding location-based strings in every language. Addresses are essential for map applications such as place search, delivery and check-ins, and they carry many local conventions. The README links to blog posts that describe the research behind it.
