Implementation and Evaluation of a German HMM for POS Disambiguation,er re-estimation and full adaption of parameters from pre-tagged corpora. The ambiguity types resolved by this model are analysed and compared to ambiguity types of English and French. Finally, the model’s error types are described. I argue that although the overall performance of these models for G

Next, we show a method for combining unsupervised and supervised rule-based training algorithms to create a highly accurate tagger using only a small amount of manually tagged te
