| 摘要: |
| 汉语多重关系复句的句法分析问题主要由复句中的关系分析和层次分析两部分组成.将多重关系复句中的层次分析作为研究对象.它是针对多种逻辑或并列关系,按照一定层次组成复杂主从关系复句而进行的关系层次分析过程.为了有效地形式化地表示多重关系复句的层次结构,提出了关系层次树的概念,并以此为基础构造文法,采用部分数据驱动的确定性移进-归约算法实现多重关系复句的关系层次分析.通过开放测试对计算机实现的多重关系复句句法分析器进行考察,93.56%的正确率使所提出的分析方法的有效性和正确性得到了充分的验证. |

| Abstract: |
| Parsing the logical embedded complex sentence in Chinese consists of recognition of both logical lelation and logical level. Recognizing of logical level, which is to parse the level in this kind of sentences with lots of logical relations, is the aim in this paper. To formalize effectively the logical level in those complex sentences, in this paper, the concept of relation hierarchical tree is defined, and in view of this concept, the grammar is designed to construct the parser for this kind of complex sentences with shift-reduce algorithm improved. The parser in this paper is evaluated in open test. The accuracy, 93.56%, shows both the effectiveness of the theory in this paper. |
