| About the quantity,can also be called the fuzzy quantity.In daily life is inseparable from the use of the quantity.This paper focuses on the structure of quantity in modern Chinese.Based on the research of Li Yuming and other scholars,we divide the approximate structure into the pre-present form(X + number + quantity),the appendage(number + quantity + X)and the middle present form(number + X +quantity),respectively,and deeply investigate its syntactic structure and semantic connotation,and on this basis,use fuzzy quantifier theory and generalized quantifier theory to make formal processing of Chinese reduction structure,explain its logical semantics and truth definition.The first chapter is the introduction,which mainly introduces the current research status,research purpose and significance,theoretical basis,research object and corpus source of Chinese approximate quantitative structure.The current research includes naming and attribution of quantifiers,expression of quantifiers,etc.The purpose and significance of the research is to reveal the syntactic structure and semantic connotation of the approximate quantity structure,and to formalize the approximate quantity structure with the relevant theoretical methods of logical semantics,so as to provide a model for natural language processing.The second chapter mainly analyzes the syntactic structure of the Chinese reduction structure.The "variable X,numeral,and quantifier" in three typical Approximate quantity structures are examined one by one.The variable "X" is rich in composition and has many types,including verb words,noun words,adverb words,etc.;Number words are basically composed of coefficient words,number words and compound number words;Quantifiers are mainly measure words and time quantifiers.Then,starting from the overall structure,discovering their other structural forms,and finally investigating the syntactic functions of these three structures,it is found that the syntactic functions of the Approximate structure are rich and can basically act as all syntactic components.The third chapter mainly analyzes the semantic connotation of the Chinese reduction structure.The Approximate structure has the semantic characteristics of [+boundary ambiguity][+central clarity][+quantity floating],and we focus on its "semantic boundary ambiguity".This boundary blurring can be divided into three types: "semantic upper limit ambiguity","semantic lower limit ambiguity" and "semantic upper and lower limit ambiguity".This ambiguity is brought by its "variant X",so we examined the semantic characteristics of "X" and we found that there are differences in the range of semantic values and the strength of ambiguity.Finally,the semantic category of the reduction structure is analyzed,which can be mainly divided into objective quantity and subjective quantity.The fourth chapter mainly uses fuzzy quantifier theory to formalize the quantity structure.In logical semantic connotation 1,the quantity results are regarded as fuzzy sets,the typical elements in different quantity structures are analyzed,and the functional expressions and images are used to draw their logical semantic expressions.Through processing,we find that the fuzzy quantifier theory is limited in dealing with the approximation structure with strong ambiguity,so we introduce the generalized quantifier theory(logical semantic Connotation 2)to supplement.Take the quantity structure as a generalized quantifier,express the limiting theory and domain theory elements it involves in the A and B sets,and define its truth condition by the cardinality of the intersection between the sets.Finally,it is found that the quantifier structure with weak ambiguity is more suitable for fuzzy quantifier theory,while the quantifier structure with stronger ambiguity is more suitable for generalized quantifier theory.The fifth chapter is the conclusion,which summarizes the main points of this paper,as well as the existing deficiencies and future prospects. |
