Empirical methods for computing phrasal and sentential semantics in Vietnamese

摘要

Abstract The purpose of this paper is to build the sets of clauses in definite clause grammar, which can express the phrasal and sentential semantics. We build these sets based on the semantic models of computational and inferential methods for analyzing the phrasal and sentential semantics in Vietnamese Question-Answering System Model (VietQASM), and implementation techniques for computing the semantics in Pham and Nguyen (Int J Simul Syst Sci Technol 17, 2016; A computational and inferential method for analyzing the semantics of phrase and sentence in Vietnamese Question-Answering System Model (VietQASM), 2015). We also present the technical novel, which expresses the process of creating the semantic expressions according to these models. Those semantic expressions will be used to make an event of data-knowledge base in the Vietnamese Question-Answering System (VietQAS). We built three sets of clauses: (1) the first set is used to define the semantic forms of lexicons, (2) the second set is used to compute and infer the semantics for phrases, (3) the third set is used to compute and infer the semantics for sentences. We only use all these sets for building a reading-comprehension mechanism for all statement sentences in the VietQAS.
