There is some good information on the wiki: http://wiki.openstreetmap.org/wiki/Name_finder/Address_format http://wiki.openstreetmap.org/wiki/Name_finder:Abbreviations Maybe a clever algorithm could use the fact that an abbreviation expansion matched for a certain language to give a higher weight to locations in countries with that language. I.e. of two hypothetical streets in the database, "Diesel St, Potsdam" would likely be in the US, whereas a (sloppily written) "Diesel Str Potsdam" would be in Germany.
