Abstract

Instance-weighting has been shown to be effective in statistical machine translation (Foster et al., 2010), as well as cross-language adaptation of dependency parsers (Søgaard, 2011). This paper presents new methods to do instance-weighting in state-of-the-art dependency parsers. The methods are evaluated on Danish and English data with consistent improvements over unadapted baselines.
