Classified Description and Application of Chinese Constitutive Role

Abstract

Constitutive role is one of the 4 qualia roles, which expresses a kind of constitutive relationship between nouns. According to the original definition and description characteristics, this paper divides the constitutive roles into two categories: materials and components. At the same time, combined with the previous methods of extracting the role automatically, this paper optimizes the method of extracting the role automatically. Relying on auxiliary grammatical constructions, we extract noun-noun pairs from large-scale corpus to extract descriptive features of constitutive roles, and then classifies these descriptive knowledge by manual double-blind proofreading. Finally, the author discusses the application of Chinese constitutive roles in word-formational analysis, syntactic analysis and synonym discrimination.
