At the same time, previous research on PCFG parsing using treebank training data present PAR-SEVAL measures in comparing the parsing performance for different languages and annotation schemes, reporting a number of striking differences. For example, Levy and Manning (2003) , Kübler (2005) , and <cite>Kübler et al. (2006)</cite> highlight the significant effect of language properties and annotation schemes for German and Chinese treebanks.
