... Therefore, the total time to compute all the I~(i, k) is O(Icl). A simi- lar argument applies to equations (4) and (5). Note that to achieve the above bound as well as to take advantage ... reestimates rule probabilities to maximize the probability that the grammar used as a stochastic generator would pro- duce the corpus. A reestimation algorithm can be used both to r...

Filtering is then performed to remove noisy frames, with methods ranging from a simple single threshold to SCF-specific hypothesis tests ... several verbs to a coarsened version of the manually-annotated gold standard used to evaluate VALEX (Preiss et al., 2007).
