Similarity Calculation of Chinese Character Glyph and its Application in Computer Aided Proofreading System
Shili Ge · Journal of Chinese Computer Systems · 2008
Chinese is a language with a large open character set.The similarity calculation of Chinese character glyph is important in automatic recognizing,computer aided proofreading,and teaching of Chinese characters.The current description method of Chinese character glyph structure is improved from the perspective of graphical similarity and an algorithm for the calculation of glyph similarity of Chinese characters without training samples of character glyphs is proposed.This algorithm possesses a better adaptability for character similarity calculation of both common-used Chinese characters and rarely-used ones whose writing samples are difficult to obtain,so as to meet the demand for character similarity calculations on the continually expanding Chinese character set.Experiment indicates that the similar character lists of 6763 characters in GB2312 calculated by this algorithm have a high coincidence with human perception.The application of the similar character lists in a computer aided proofreading system improves the modification guide for users.
