1 shows the tremendous reduction in parsing time (all times are cumulative) and gives an overview over grammar sizes and parsing accuracies.
in our Java implementation on a 3GHz processor, it is possible to parse the 1578 development set sentences (of length 40 or less) in less than 1200 seconds with an F 1 of 91.2% (no search errors), or, by pruning more, in 680 seconds at 91.1%.
