Saarburg, Germany vs Saarebourg, France #5006
Comments
Author: lonvia The French town is a perfect name match (through the name:de tag) and deemed more important than the German town. twain, is that one of the cases the new wikipedia importance weights would improve? |
Author: twain No. To fix this we'd have to add per-language name weighting. And some way to determine which name is the most important. Very tricky. |
Author: lonvia True, tricky to decide in the general case. I was wondering if that particular case of Saarburg is actually a case of overlinking in French wikipedia I remember you mentioning once. http://nominatim.openstreetmap.org/details.php?place_id=97934108 seems overrated. |

hi as I am from the region AND just between the two cities ;-) what do you think about to delete the de:Saarburg tag in Saarebourg? |
Author: twain Importance from the new algorithm the french Saarburg drops to 0.48, the german one ends up at 0.51. So yes the new scores would resolve this. |
Author: lonvia The use of the name:de tag is not exactly wrong here but not really helpful as Nominatim expects to find the most frequently used variant in the name tag. I'd suggest to move it to one of the alternative name tags, e.g. alt_name:de or official_name:de. Then it can still be found but it will not appear first anymore (or be listed under the name 'Saarburg' which is probably also rather unexpected in this case). I'll close this a wontfix, as it is not really decidable for the general case. (Or rather far too much effort.) |

When I search a route from or to "Saarburg" in Germany
for example with osrm, openrouteservice or graphopper
they always offer Saarebourg in France.
OSM offers as well as the first option Saarebourg in France.
