Venue Annual Meeting of The European Chapter of The Association of Computational Linguistics

Faced with the problem of annotation er- rors in part-of-speech (POS) annotated corpora, we develop a method for auto- matically correcting such errors. Build- ing on top of a successful error detection method, wefirsttry correcting acorpus us- ing two off-the-shelf POS taggers, based on the idea that they enforce consistency; with this, we find some improvement. Af- ter some discussion of the tagging process, we alter the tagging model to better ac- count for problematic tagging distinctions. This modification results in significantly improved performance, reducing the error rate of the corpus.
