The study of syntactic-semantic interface has always been an important part of linguistics and natural language processing (NLP) research, and the introduction of events into it can provide a consistent object for syntactic-semantic research. In the system of Chinese Parataxis Graph (CPG), event is a chunked description of sentence semantics, and the analysis of event structure provides an effective perspective for the semantic analysis. However, the academic research on event structure is mostly theoretical and lacks relevant data statistics. In this paper, we measure and analyse the syntactic representations of event structures based on CPG Annotated Corpus, to reflect the distribution of the syntactic positions of event words when the event structures are mapped to syntactic structures, as well as the presence or absence and co-occurrence of the core arguments of events that are mapped to different syntactic structures, and analyzing some of the data.
