... incomplete analysis. Several partial parsing strategies have been proposed (Kasper et al., 1999; Zhang and Kordoni, 2008) as the robust fallbacks for the parser when no available analysis can be derived. ... features are used. Parser performances are measured using both labeled and unlabeled attachment scores (LAS/UAS). For unlabeled CHILDES* data, only UAS numbers are reported. Table 4 and...
