We present an improved training strategy for dependency parsers that use online re- ordering to handle non-projective trees. The new strategy improves both efficiency and accuracy by reducing the number of swap operations performed on non-project- ive trees by up to 80%. We present state-of- the-art results for five languages with the best ever reported results for Czech.
