GeoNames Forum

Hi,
I am trying to validate a list of strings.
Each string is supposed to contain information about a location which a user wrote manually.
In general, the strings have a format like this: "City, Region, Country".
Quite a lot of times the user misspelled a part of the location string e.g. "Brelin" instead of "Berlin".
Is there a intelligent mechanism to validate a Country, City etc with the Geonames API?
Is there a possibility to calculate the likelyhood of a Fuzzysearch result?

Thanks for your help!
