汉字字形加工的关键特征模型

Critical Feature Model of Chinese Character Processing

现有的汉字识别模型对汉字的字形加工过程并没有达成共识。争论的焦点是汉字识别中的字形加工究竟是特征分析还是整字加工占优势。汉字字形加工中采用的是任务引导的识别策略,汉字字形加工的关键特征验证模型包括了汉字字形加工过程中的自上而下和自下而上两种信息加工,强调识别过程中根据字形的关键特征的验证。

Chinese characters, differing from alphabetic writing systems, are usually referred to as ideographs. Despite the intensive and sophisticated research on visual Chinese character recognition, there are still some questions concerning the processes involved in lexical access unresolved. One such issue is whether or not Chinese character recognition is achieved by processing the holistic visual configuration of a character or by the mediation of component by component identification. A critical feature model of Chinese character is perhaps the most fruitful approach. The critical feature approach involves both top down and bottom up processing, with the emphasis on the check of critical feature during the process of recognition.
