Research On The Semantic Restriction Based On The Syntax Realization Of The Additional Role Category In The Semantic Knowledge Base

The "syntax-semantic" interface research is a research hotspot in the fields of language information processing and syntactic semantics,and the syntactic realization of the role category is an important part of the "syntax-semantic" interface.In the "syntax-semantic" interface,the implementation of the additional role category syntax is governed by the co-occurrence predicate,the corresponding word,phrase structure,the semantic framework formed by the role category and predicate,and the constraints and conventions of various pragmatic factors.In the whole "syntax-semantic" process,lexical semantics and structure play the role of the underlying semantic constraints.Based on the semantic knowledge base,this paper takes 10 additional role categories as the research object,from the two dimensions of lexical semantics and semantic framework,the semantics between the co-occurrence predicates,the basic role categories and the corresponding lexical structures of the additional role categories.The constraint relationship is studied and discussed,and on this basis,the syntactic realization of each additional role category is investigated to reveal the semantic constraint mechanism of the additional role category syntax implementation.Specifically:At the level of lexical semantics,firstly,3874 predicates co-occurring with the additional role categories are extracted,and semantic classification is carried out.In the classification of predicates,the demand types and constraints of additional roles on predicates are discussed.Thirdly,the 3325 words and 618 phrase structures corresponding to the additional characters are extracted,and which semantic class is used to examine the additional role categories,so as to explore the semantic requirements types and constraints of the additional role categories and corresponding vocabulary and phrase structures.On the syntactic and semantic level,based on the classification of predicates,191 kinds of additional role categories and predicate semantic framework types are further summarized.In the framework,the combination characteristics and semantic constraints of additional role categories and predicates are analyzed.And in the framework of the generalization,the frequency of co-occurrence of additional roles and basic roles is counted,and the preferred sequence of 10 additional role categories for the basic role category and the preferred sequence of 5 basic roles for additional roles are summarized to discuss the additional role pairs.The type of demand and constraints of the role.Finally,we examine the syntactic realization of the additional role category.That is,the syntactic projection priority type of the additional role category is examined horizontally,and the priority position type of the additional role category is examined longitudinally.On this basis,we study the relationship between lexical structure,syntactic position and role category,that is,to refine the semantic class of the additional role category projected as the syntactic position,and to examine which syntactic category can be implemented as a syntactic position.Through the discussion of the above three groups of relationships,the semantic mechanism of the syntactic implementation of the additional role category is finally revealed.Based on the semantic knowledge base,this paper explores the semantics of the additional role category in the realization of the additional role category.The additional role category is subject to the co-occurrence predicate,the co-occurrence basic role category and its corresponding lexical and structural semantic conventions and restrictions.However,due to various issues such as personal ability,time and corpus,research is still very shallow.More work needs to be done to further study the semantic constraints of additional role categories and predicate verbs in the comparison of additional roles and basic roles.
