Zusammenfassung
Pure statistical parsing systems achieves high in-domain accuracy but
performs poorly out-domain. In this paper, we propose two different
approaches to produce syntactic dependency structures using a
large-scale hand-crafted HPSG grammar. The dependency backbone of an
HPSG analysis is used to provide general linguistic insights which,
when combined with state-of-the-art statistical dependency parsing
models, achieves performance improvements on out-domain tests.
