In this paper we present a new approach to morphosyntactic tagging of Polish by bringing together Conditional Random Fields and tiered tagging. Our proposal also allows to take advantage of a rich set of morphological features, which resort to an external morphological analyser. The proposed algorithm is implemented as a tagger for Polish. Evaluation of the tagger shows significant improvement in tagging accuracy on two state-of-the-art taggers, namely PANTERA and WMBT.
