摘　　要：根据现代汉语中指示代词和所指对象的位置关系,指代一般可分为3种类型:前指、后指和外指。针对前指型指示代词的“代名词”形式,分析代词的指代特点,以概念格(本体)为理论基础,建立概念从属树及名词概念的描述,表示概念之间的属性继承关系,进行无语义转换统一体内的代词先行词确定的研究,实现了其中用“就近概念从属匹配”原则确定先行词的部分,体现了代词的语义功能,并在初中几何智能解题系统中得到了成功应用。Based on position relation between demonstrative pronouns and its referring objects, reference is divided into anaphora, cataphora and exphora. According to anaphoric demonstrative pronouns substituted noun, its character is analyzed, concept dependency tree and the description of noun concept is established, which is based on the theory of concept lattice and represented the relationship of attribute inheritance between the concepts. Thereby, the selection of pronoun antecedent in the non-transformed semantic entity is researched and implemented under the principal of proximate concept dependency matching, the semantic function of pronoun is embodied and is successfully applied in intelligent solution system of plane gfometry.
