Parsing results for the unconstrained (no-c) and the constrained (c) ILP models, and the Bohnet parser in terms of F-score (LAS) for core grammatical functions marked by case. We omit locative objects in Czech, and second accusative objects in German because of their extremely low frequency. * Statistically significant when comparing the performance on a grammatical function for the C model to the pred-m model (α = 0.05, two-tailed t-test for related samples).
