+ | ===== Bulgarian (bg) ===== | ||

+ | |||
+ | The main reasons why the implementation took so long: | ||
+ | * Necessity to re-work the system of main word classes, especially pronouns. | ||

+ | * Driver tester required that encode(decode(x))=x. However, the CoNLL incarnation of the tags was inconsistent, | ||
