摘要
本文提出用句法主语考察篇章主题表现力的新思路。首先界定了主题、主题聚合度、主题表现力概念,用提取篇章中的主语并形成语义聚类的量化方法来评价主题表现力的集中度和丰富度。其次,给出了句法主语检测主题表现力的操作程序,设计了主题表现力的5项指标。最后用多元线性回归方程对33篇中学作文的主题表现力进行了初步验证。实验证明,主语的聚类数量与作文水平成正相关,相关系数0.75;主语主题表现力效果值与作文水平呈现正相关,相关系数为0.82。
A new methodology is used to study the expressiveness of the theme of an article from the perspective of the subject. After the definitions of the theme, the expressiveness and the polymerization degree of the theme, a qualitative method of subject extracting and semantic clustering is adopted to evaluate the polymerization and expressiveness of the theme. An operative procedure with five parameters for verification of the method is designed. Then the expressiveness of the themes of 33 compositions by junior high school students is assessed using multiple linear regression equation. The results show that the number of the subject clusters and the expressiveness of the themes created by the subjects are both positively correlated with the writing performance, the correlation coefficient being 0.75 and 0.82.
