... grammar compatible annotations to train the statistical components. 2 Parser Domain Adaptation In recent years, two statistical dependency parsing systems, MaltParser (Nivre et al., 2007b) and MSTParser ... parsing, while the domain adaptation of the dependency parsing has not been fully explored. Taking a different approach towards parsing, grammar-based parsers appear to have m...

We can also verify that the parsing accuracy improves by using imprecise information obtained from an automati- call...
