Most current dependency parsers presuppose
that input words have been morphologically
disambiguated using a part-of-speech tagger
before parsing begins. We present a transitionbased system for joint part-of-speech tagging
and labeled dependency parsing with nonprojective trees. Experimental evaluation on
Chinese, Czech, English and German shows
consistent improvements in both tagging and
parsing accuracy when compared to a pipeline
system, which lead to improved state-of-theart results for all languages.
