TAILIEUCHUNG - Báo cáo khoa học: "THE RESOLUTION OF QUANTIFICATIONAL AMBIGUITY IN THE TENDUM SYSTEM"

A method is described for handling the ambiguity and vagueness that is often found in quantifications - the semantically complex relations between nominal and verbal constituents. In natural language certain aspects of quantification are often left open; it is argued that the analysis of quantification in a model-theoretic framework should use semantic representations in which this may also be done. This paper shows a form for such a representation and how "ambiguous" representations are used in an elegant and efficient procedure for semantic analysis, incorporated in the TENDUM dialogue system. . | THE RESOLUTION OF QUANTIFICATIONAL AMBIGUITY IN THE TENDUM SYSTEM Harry Bunt Computational Linguistics Research Unit Dept of Language and Literature Tilburg University 90153 5000 LE Tilburg The Netherlands ABSTRACT A method is described for handling the ambiguity and vagueness that is often found in quantifications - the semantically complex relations between nominal and verbal constituents. In natural language certain aspects of quantification are often left open it is argued that the analysis of quantification ỉn a model-theoretic framework should use semantic representations in which this may also be done. This paper shows a form for such a representation and how ambiguous representations are used in an elegant and efficient procedure for semantic analysis incorporated in the TENDUM dialogue system. The quantification ambiguity explosion problem Quantification is a complex phenomenon that occurs whenever a nominal and a verbal constituent are combined in such a way that the denotation of the verbal constituent is predicated of arguments supplied by the denotation of the nominal constituent. This gives rise to a number of questions such as 1 What objects serve as predicate arguments 2 Of how many objects is the predicate true 3 How many objects are considered as potential arguments of the predicate When we consider these questions for a sentence with a few noun phrases we readily see that the sentence has a multitude of possible interpretations. Even a sentence with only one NP such as 1 Five boats were lifted has a variety of possible readings depending on whether the boats were lifted individually collectively or in groups of five and on whether the total number of boats involved is exactly five or at least five. For a sentence with two numerically quantified NPs such as Three Russians visited five Frenchmen Partee 1975 distinguished 8 readings depending on whether the Russians and the Frenchmen visited each other individually of collectively and on the
