摘　　要：该文提出了以谓词为核心的块依存语法,以谓词为核心,以组块为研究对象,在句内和句间寻找谓词所支配的组块,利用汉语中组块和组块间的依存关系补全缺省部分,明确谓词支配关系。根据块依存文法体系,目前共标注2199篇文本,涵盖百科、新闻两个领域,共约180万字语料。该文简述了块依存文法的原则,并对组块及其依存关系进行了定义。该文详细介绍了标注流程、标注一致率、数据分布等情况。基于现有的树库,该文发现汉语中有约25%的小句是非自足的,约有88%的核心谓词可支配1~3个从属成分。This paper presents a Chinese Chunk-Based Dependency Grammar(CCDG).With this grammar,predicate-dominated chunks can be found within and between sentences,and default parts of sentences can be completed by the relations between chunks.This paper describes the principles of CCDG and defines the chunks and relations.We have annotated 2199 texts,altogether 1800,000 words from encyclopedia and news texts based on the CCDG.The annotation procedure,label consistency,data distribution,and so on are described in detail.Based on current treebank,it is found that about 25%of clauses in Chinese are not self-sufficient,and about 88%of core predicates govern 1-3 subordinate components.
