Enriching postal addresses with Elastic stack

A presentation at London Information Retrieval Meetup by David Pilato

Come and learn how you can enrich your existing data with normalized postal addresses with geo location points thanks to open data and BANO project.

Most of the time postal addresses from our customers or users are not very well formatted or defined in our information systems. And it can become a nightmare if you are a call center employee for example and want to find a customer by its address. Imagine as well how a sales service could easily put on a map where are located the customers and where they can open a new shop…

Let’s take a simple example:

  "name": "Joe Smith",
  "address": {
    "number": "23",
    "street_name": "r verdiere",
    "city": "rochelle",
    "country": "France"

Or the opposite. I do have the coordinates but I can’t tell what is the postal address corresponding to it:

  "name": "Joe Smith",
  "location": {
    "lat": 46.15735,
    "lon": -1.1551

In this live coding session, I will show you how to solve all those questions using the Elastic stack.
