Automatic correction of part-of-speech corpora.
In: Speech and language technology, Vol. 11: S. 167-174
In this study a simple method for automatic correction of part-ofspeech corpora is presented, which works as follows: Initially two or more already available part-of-speech taggers are applied on the data.
Then a sample of differing outputs is taken to train a classifier to predict for each difference which of the taggers (if any) delivered the correct output.
As classifiers we employed instance-based learning, a C4.5 decision tree and a Bayesian classifier. Their performances ranged from 59.1 % to 67.3 %. Training on the automatically corrected data finally lead to significant improvements in tagger performance.
