As Google adds ten more languages to its machine translation service, it seems to be on its way to becoming the most convenient universal translator of the world’s popular languages. Google’s handling of languages of course isn’t perfect, however—in particular, I’ve been complaining to friends for a while about the weaknesses of Google’s handling of queries in Chinese character (漢字/汉字) scripts. In this post, I run some tests using Google’s Language Detection service to try to better understand its handling of Chinese character queries.

Background

Chinese characters have been used all across East Asia, most notably in Chinese, Japanese, Korean, and Vietnamese (the “CJKV”). Prescriptivist writing reforms in Communist China and Japan have simplified many characters, though. Some characters were simplified in the same way, some in different ways, and some in only one country but not the other. For more information, there’s Wikipedia or Ken Lunde’s CJKV Information Processing.

The problem

The issue comes up when you try to search for a word in Chinese characters which clearly came from one Chinese character-using language. From my experience, Google doesn’t consider which language you are a user of, based on the query, and returns many results in other Chinese character-using languages as well.[^1]
