What's interesting to me about the Mediawiki implementation is it has some features of a fully fledged rule-based machine translation system. It implements several layers of translation. In increasing level of precision, but also increasing effort and decreasing recall:
1. character to character conversion - originally based on tables from unicode
2. word/phrase type structure level matching - based on their own lists
3. domain specific word/phrase lists, (I'm not sure if this is based on category, opt in by including a template or both) see https://zh.wikipedia.org/wiki/Category:%E5%85%AC%E5%85%B1%E8%BD%89%E6%8F%9B%E7%B5%84%E6%A8%A1%E6%9D%BF https://zh.wikipedia.org/wiki/Category:%E5%85%AC%E5%85%B1%E8... (I can't read Chinese - figured it out with Google Translate)
4. rules which apply for a whole article, see https://zh.wikipedia.org/wiki/Help:%E4%B8%AD%E6%96%87%E7%BB%B4%E5%9F%BA%E7%99%BE%E7%A7%91%E7%9A%84%E7%B9%81%E7%AE%80%E3%80%81%E5%9C%B0%E5%8C%BA%E8%AF%8D%E5%A4%84%E7%90%86#%E6%8E%A7%E5%88%B6%E8%87%AA%E5%8A%A8%E8%BD%AC%E6%8D%A2%E7%9A%84%E4%BB%A3%E7%A2%BC https://zh.wikipedia.org/wiki/Help:%E4%B8%AD%E6%96%87%E7%BB%...
5. rules which apply for a single word, see previous link
The whole thing is explained here: https://zh.wikipedia.org/wiki/Help:%E4%B8%AD%E6%96%87%E7%BB%B4%E5%9F%BA%E7%99%BE%E7%A7%91%E7%9A%84%E7%B9%81%E7%AE%80%E3%80%81%E5%9C%B0%E5%8C%BA%E8%AF%8D%E5%A4%84%E7%90%86#%E8%BD%AC%E6%8D%A2%E6%8A%80%E6%9C%AF https://zh.wikipedia.org/wiki/Help:%E4%B8%AD%E6%96%87%E7%BB%...
The last 3 points address level 4 of Chinese character conversion mentioned in this article: http://www.cjk.org/cjk/c2c/c2cbasis.htm http://www.cjk.org/cjk/c2c/c2cbasis.htm
I think OpenCC only implements level 1 and 2. I've looked at the source code to see that OpenCC gets "words" by using greedy longest prefix matching rather than fancier "Chinese word segmentation" -- I would guess MediaWiki does the same.
