汉字书写评价与指导的信息化需求，促进了书写质量智能评价技术方案的研究以及付诸教学实践。既有“关键笔画+逐步蔓延”方案经历了三年的书写教学实验后，研究站在汉字历史、文化以及日常书写识读立场上，确立了新的书写正确性综合判定思想以及书写细节纠错的评价目标。研究优化先前正确性评价指标体系，采取笔画类型、空间关系等构字要素逻辑地位等同评价策略，设计了基于综合特征匹配的汉字书写正确性评价方案。针对该综合匹配方案，根据实效进行了笔画形态、相对位置等正确性评价指标特征权重的调整。为验证面向教学应用的效果，设计了“恶意书写场景”下的新旧方案的对比测试，结果表明，综合方案对错字的判定率相较于旧方案的93%进一步提高到97.5%，并在错误细节发现上有质的突破，达到89.9%；设计了“数据真实”情境下的一般性测试，结果表明，综合方案在汉字书写教学实践数据抽样样本的正确性评判与人工评判的一致性上达到98.22%，可以更好地支持新一阶段汉字书写教学信息化实践的应用需求。
【英文摘要】：
The information requirements for evaluation and guidance of Chinese character writing have promoted the research and teaching practice of technical schemes of intelligent evaluation for writing quality. After three years of writing teaching experiments based on "key strokes + gradual spread" program, this study establishes a new idea of comprehensive judgment of writing correctness and the evaluation target of correction of writing details based on the history, culture and daily reading and writing of Chinese characters. This study optimizes the previous correctness evaluation index system, adopts the logical status equivalent evaluation strategy of constituent elements such as stroke type and spatial relationship, and designs an evaluation scheme for writing correctness of handwritten Chinese characters based on comprehensive feature matching. For the comprehensive matching scheme, the feature weights of the correctness evaluation indicators such as stroke form and relative position are adjusted according to the actual effect. In order to verify the application effect, a comparison test between the old and new schemes under the "malicious writing scenario" is designed. The results show that compared with the old scheme, the judgment rate of wrong words in the comprehensive scheme is further improved to 97.5%, and there is a qualitative breakthrough in the positioning of error details, reaching 89.9%. The general test under the "data reality" scenario is carried out, and the results indicate that the consistency between the comprehensive correctness evaluation and the manual judgment reaches 98.22% based on the data sampling in Chinese character writing teaching practice, which can better meet the application needs of Chinese character writing teaching in the new stage.
