As an example, https://www.openstreetmap.org/relation/3970414 is a relation
for a district named as "Dalseo-gu" in Korea. To transliterate Korean name
into Chinese or Cantonese language, the general rule is that one need to
identify the etymology root of the Korean word. In this case it is "Dal
City (Ancient name of Daegu)'s Western District". The best software that
can do this matching is Google Translate the machine translation site but
even they can only offer ~90% accuracy in identify name of places (They
failed in this example), and that's barring name of places that don't
follow this rule including all Korean name that have no Chinese roots.
Those words need to independently phonetically or etymologically
translated. After identifying the etymological root, one can then
transmiterate the etymological root into Chinese characters, which have a
smaller but still non-zero chance of failing due to the simplification rule
of the Chinese character system especially for the Simplified Chinese. And
then in the end "Dalseo-gu" in Korean will be translated into "Daxiqu" in
Mandarin Chinese and "Datsaikui" in Cantonese.
