Here is an example of the final character sequence representation for the word pair vsfuret -ausführt '(he) leads out': (1) v s f u r e t a u s füh r t A consequence of this approach is that our labels cannot only be characters, but also combinations of characters (such asüh in the example above); our label set is therefore potentially unbounded.
for the other methods, adding the 10,000 randomly selected samples to the training set actually decreases the average accuracy, by −0.4 pp for Norma and −2.0 pp for CRF.
