摘要
为有效提高方块苗文的输入速度,提出一种方块苗文输入的音形编码新方法,并用上下文无关文法给出该方法的形式化定义.该方法是将方块苗文输入编码序列设计为"2个音码+2个形码"的4码形式,与文字本身读音无关.音码由方块苗文首构件和末构件的汉语拼音首字母决定,形码由方块苗文本身的末笔画名称和结构类型名称的汉语拼音首字母决定.测试实验结果表明,较之前期已实现的方法,该方法不但简单规范、易学易用,而且具有更低的重码率、更快的输入速度和更高的输入正确率.
In order to effectively improve the speed of inputting Hmong characters,a novel phonetic-shape encoding method is proposed.Formal definition of the method is given in the framework of context-free grammar.The proposed method is utilized to realize to input Hmong characters by combining with phonetic code and shape code.According to this method,the input coding sequence of a Hmong character is independent of the pronunciation of the character itself,and is considered as a combination of two phonetic codes and two shape codes.The phonetic codes are determined by the Chinese pinyin initials of the first component and the final component.The shapes codes are determined by the Chinese pinyin initials of the names of the last stroke the font structure,respectively.Experimental results show that compared with the previous method,the proposed method achieves the predetermined goals in terms of higher learnability and usability,lower coding repetition rate,faster input speed,and higher input correctness.
