Fuzzy Quantifiers: A Natural Language Technique for Data Fusion
Fuzzy quantifiers like ‘almost all’ and ‘about half’ abound in natural language. They are used for describing uncertain facts, quantitative relations and processes. An implementation of these quantifiers can provide expressive and easy-to-use operators for aggregation and data fusion, but also for steering the fusion process on a higher level through a safe transfer of expert-knowledge expresse...
متن کامل. Wstęp
In the thesis computational semantics for monadic quantifiers in natural language in the spirit of J. van Benthem’s works [van Benthem 1986] is considered. The possible correlations between quantifiers and procedures which can be used to compute quantifiers’ denotations in finite models are discussed. We prove M. Mostowski’s theorem that monadic quantifiers definable in the divisibility logic a...
متن کاملComputational complexity of polyadic lifts of generalized quantifiers in natural language
We study the computational complexity of polyadic quantifiers in natural language. This type of quantification is widely used in formal semantics to model the meaning of multi-quantifier sentences. First, we show that the standard constructions that turn simple determiners into complex quantifiers, namely Boolean operations, iteration, cumulation, and resumption, are tractable. Then, we provide...
متن کاملAnalyzing fuzzy and contextual approaches to vagueness by semantic games
How can natural language be ‘understood’ by computers? Or, more specifically, how can the semantics of a natural language statement be modeled by means of logic in order to facilitate formal reasoning? This perennial problem has many, partly intertwined facets; one of them being the pervasiveness of vagueness in all natural languages. Originally discarded by Frege as a ‘defect’ of ordinary lang...
متن کاملA Formal Theory of Fuzzy Natural Language Quantification and its Role in Granular Computing
Fuzzy quantification is a linguistic granulation technique capable of expressing the global characteristics of a collection of individuals, or a relation between individuals, through meaningful linguistic summaries. However, existing approaches to fuzzy quantification fail to provide convincing results in the important case of two-place quantification (e.g. “many blondes are tall”). We develop ...
