20 Boulevard St-Michel, Paris, France

Open missinglink opened this issue 5 years ago • 1 comments

Hi!

This is an interesting test case which produces different parses depending on how the street name is specified:

20 Boulevard St-Michel, Paris, France


My country is

France


Here's how I'm using libpostal

Pelias Geocoder


Here's what I did & what I got

> 20 Boulevard St-Michel, Paris, France

Result:

{
  "house_number": "20",
  "road": "boulevard st-michel",
  "city": "paris",
  "country": "france"
}
> 20 Boulevard St Michel, Paris, France

Result:

{
  "house_number": "20",
  "road": "boulevard",
  "suburb": "st michel",
  "city": "paris",
  "country": "france"
}
> 20 Boulevard Saint Michel, Paris, France

Result:

{
  "house_number": "20",
  "road": "boulevard",
  "suburb": "saint michel",
  "city": "paris",
  "country": "france"
}

Here's what I was expecting

  "house_number": "20",
  "road": "boulevard st-michel",

For parsing issues, please answer "yes" or "no" to all that apply.

  • Does the input address exist in OpenStreetMap? https://www.openstreetmap.org/node/2553153336 https://www.openstreetmap.org/node/3172251267
  • Do all the toponyms exist in OSM (city, state, region names, etc.)? yes
  • If the address uses a rare/uncommon format, does changing the order of the fields yield the correct result? As shown above
  • If the address does not contain city, region, etc., does adding those fields to the input improve the result? N/A
  • If the address contains apartment/floor/sub-building information or uncommon formatting, does removing that help? Is there any minimum form of the address that gets the right parse? N/A

Here's what I think could be improved

The synonyms seem to be correct so I'm not sure what's going on...
