摘要
自然语言处理研究进入句处理阶段以后,无论基于规则还是基于统计的策略,都面临"句法—语义"接口或界面问题。本文基于大规模语义知识库,从词汇语义和句法语义两个维度,按照"词汇单位—角色转化—范畴排序—句法实现"的思路,以手部动作义场中"打"子场为典型个案,考察词汇单位凭借范畴义征实现为角色范畴的机制、角色的排序机制以及角色的句法配位规律,揭示了词汇语义对角色范畴句法实现的制约特点,以及角色的排序模式和句法实现的位置特点。
Natural language processing faces the problem of ＂ syntax-semantics＂ interface at the stage of semantic processing, be it rule-based or statistics-based. On the basis of a large-scale knowledge base, this paper investigates the mechanism of lexical units transforming into role categories by means of semantic features, the mechanism of role sorting and the syntactic realization rule of the roles. Analyses are made from the perspectives of lexical semantics and syntactic semantics under the process framework of ＂lexical unit--semantic role transformation--sorting of semantic categories--syntactic realization＂ , with the semantic field ＂Da＂ as a typical example. The paper expounds the constraint of lexical semantics on the syntactic realization of the role category, and also summarizes the sorting pattern of the role category and the position of syntactic realization.
