1) main branch angles
主枝夹角
2) within-subtopic-field angle
主题域内夹角
1.
A subtopic-field segmentation technique based on the optimal control model was proposed,the object function of the optimal control model was constructed by the within-subtopic-field distance,the between-subtopic-field distance,the within-subtopic-field angle and the between-subtopic-field angle.
提出一种基于最优化控制模型的文本主题域划分方法,采用主题域内距离、主题域间距离、主题域内夹角和主题域间夹角等相关要素,构建了最优化模型的目标函数,进而通过对模型求解得到文本主题域的最优划分模式。
3) between-subtopic-field angle
