联机汉字篇章书写质量评价研究

Automatic Evaluation of Quality of Online Written Chinese Chapter

该文的研究工作针对硬笔汉字篇章书写练习的智能评价与指导需求展开。在PAD等数字录入设备支持的联机书写状态下,以记录书写笔迹的时序点集为依据,先实现分行割字,再进行行水平、行间距稳定性、行间距均匀性、字间距均匀性和左对齐等的计算并获得特征参量。最终通过专家经验赋权法给出直观的书写质量评价结果。实验表明,该系统可以对篇章书写质量给出较符合主观习惯的评价,能够用于指导书写者进行汉字篇章书写练习。

This paper investigates the automatic evaluation of online written Chinese chapters for hard-pen writing practice via digital input devices such as PAD.Based on the time-point sets of handwriting,we first extract lines and words,and then calculate the line level,line spacing stability,line spacing uniformity,word spacing uniformity,and left alignment.Based on these characteristic parameters,an expert-driven heuristic is derived to generate the writing quality score.The experiments show that the system can provide a result relatively consistent to the subjective evaluations.
