Language Guessing
There are a number of ways to guess languages. Why would you want to do that? Well if you have a piece of test you might want to know what language it is written in. The Sonnet project (building a spell checking framework for KDE) is using it to guess the language of your text so that it can adjust its operation to spell check in the appropriate language.
We’ve just submitted the data needed to guess the remaining South African languages. So that when Sonnet becomes part of KDE4 it will guess South African languages correctly.
