If you’ve ever struggled with messy addresses, especially the ones from halfway across the globe that seem like they were written by throwing darts at a map, Libpostal is here to save the day. This open-source, address-parsing and normalization library is the quiet hero behind many applications that deal with location data. Here’s everything you need to know about it, along with some fun insights.
What Exactly is Libpostal?
Libpostal is a library designed to parse and normalize addresses from nearly any format, language, or structure. Born out of a need for flexibility and precision, it translates the “creative” ways people write addresses into something standardized and functional.
Libpostal works wonders with international addresses that might otherwise stump traditional address parsers. It doesn’t just understand that “Av. de la Constitución 15” in Spain means the same thing as “Constitution Ave 15” in an English-speaking country; it formats, normalizes, and adapts to each address’s quirks. If you’re dealing with global data, this is a powerful asset.
How Does It Handle “Messed-Up” International Addresses?
If you’re wrangling a mixed bag of international addresses, Libpostal can make sense of them with remarkable accuracy. From abbreviations and alternate spellings to different regional structures, it has a way of figuring out what’s what. Let’s say you’ve got addresses from Japan, Germany, and Nigeria — Libpostal can parse and normalize each with surprising precision, reducing the noise for your application and improving data consistency.
Customizing Your Address Format Preferences
One size doesn’t fit all when it comes to addresses, and Libpostal gets that. You can customize address formats to suit your needs, whether it’s tweaking the output to conform to local standards or simply making it more readable for your users. Through flags and configuration options, you can direct Libpostal to format addresses based on specific countries or standards, giving you a consistent result that aligns with the local norms.
Running Libpostal Locally on a Mac
If you’re keen on privacy, running Libpostal locally is a safe bet. Here’s why:
1. Security
- Running Libpostal on your machine means you maintain complete control over the data. No addresses are sent to the internet or third-party servers when processed locally, making it a more secure option for those sensitive about their data.
2. Privacy
- When running locally, the data stays on your device. Nothing goes out; everything stays in.
3. Installation
- Setting up Libpostal on a Mac requires some command-line skills, but here’s a straightforward guide:
- Installation Steps:
- Install Homebrew if you don’t already have it.
- Open your terminal and type:
brew install autoconf automake libtool pkg-config
- Clone Libpostal directly from its GitHub repository:
git clone https://github.com/openvenues/libpostal
- Move into the
libpostaldirectory:
cd libpostal
- Build and install Libpostal:
./bootstrap.sh
./configure
make
sudo make install
Once installed, you’re all set to use Libpostal with Python.
Address Normalization in Python
If you have a list of addresses that need cleaning, using Libpostal with Python makes life easy. Here’s a simple script to normalize addresses:
import postal.parser
import postal.expand
# Sample list of 3 addresses
addresses = ["123 Main St, Anytown, USA", "Schönhauser Allee 175, Berlin, Germany", "1 Chome-1-2 Oshiage, Sumida City, Tokyo, Japan"]
# Function to normalize addresses
def normalize_addresses(addresses):
normalized = []
for address in addresses:
expansions = postal.expand.expand_address(address)
normalized.append(expansions[0]) # Choose the first expansion (most common format)
return normalized
# Normalize addresses
cleaned_addresses = normalize_addresses(addresses)
print(cleaned_addresses)
This script takes your list of addresses and uses the postal.expand module to generate a standardized version for each. Need something more specific? Tweak the expansion settings in Libpostal to adjust the output based on your unique needs.
