PARSING AND INTERPRETING QUANTIFIERS WITH GETARUN
Denise Dibattista, Emanuele Pianta, Rodolfo Delmonte · 1999
GETARUN the system for text understanding developed at the University of Venice contains an integrated set of algorithms to compute quantifier scope efficiently. The algorithm for Quantifier Raising is coupled to a procedure that checks whether a given utterance may be interpreted as generic assertion on the basis of a certain number of linguistic conditions dependent on tense, mood, frequency temporal adjuncts etc. Then QR is started and in case quantifiers need to be given scope this will be indicated by introducing an operator-variable pair in the f-structure. This information is then used by the algorithm of Pronominal Binding in order to find antecedent-pronominal pairs. Subsequently, the Discourse Level Anaphora Resolution Module may inherit information modified by the presence of a quantifier. The Semantic Interpretation Module will look for scope information when applying semantic rules for the creation of semantic individuals. This distributed architecture allows a treatment of quantifiers which is then finally recorded in the unscoped Discourse Model, which is used as input for both the Generation and the Reasoning Modules.
