摘要
词是自然语言处理中最基本的单位．在当今知识表示领域，知识图作为自然语言理解的语义模型有其独到之处．本文从语言学和逻辑学的角度，首次提出并探讨了逻辑词．研究逻辑词的分类及如何用知识图表示各类逻辑词的结构．
Knowledge graph theory is a new method for knowledge representations. In this theory word graphs are used to represent natural language text. The central point of knowledge graph theory is the stress that structure is meaning. The basic structure is the graph of a word. From word graphs we can build text graphs. We already built word graphs for prepositions and adwords (including adjectives, adverbs and Chinese quantity words). In this paper, we focus on the words of logical meanings. We first define a logic word and classify the logic words into 8 groups in terms of logic and semantics. Furthermore, we study the lexicons of logic words in knowledge graphs.
