This paper evaluates the impact of external lexical resources into a CRF-based joint Multiword Segmenter and Part-of-Speech Tagger.We especially show different ways of integrating lexicon-based features in the tagging model.We display an absolute gain of 0.5% in terms of f-measure.Moreover, we show that the integration of lexicon-based features significantly compensates the use of a small training corpus.
