Not surprisingly, the results shown in Table 4 (all triggers) and 5 (verbal triggers) are overall lower than when using gold features.
switching from surface to deep syntax leads to higher gain for predicted data than for gold data: 5.1 points (56.7 to 61.7) for all trigger, instead of 4.2 for gold data and 6.7 points (61.3 to 68) instead of 6.4 on gold data for verbal triggers.
