While the mean number of scope readings in the subcorpus is in the millions, our system computes on average 4.5 weakest readings for each sentence, in less than twenty milliseconds; over 80% of all sentences are reduced to at most two weakest readings.
we make it feasible for the first time to build an application that uses the individual (weakest) semantic representations computed by the ERG, both in terms of the remaining ambiguity and in terms of performance.
