In a method for calculating a similarity between Chinese character strings based on an editing distance, a similarity between Chinese characters in to-be-compared character strings is first calculated, and then a similarity between the to-be-compared Chinese character strings is calculated. In this method, Chinese characters in character strings are converted into four-corner code by using four-corner coding, so that a similarity between the Chinese characters is calculated based on an editing distance; and on this basis, a weight of the editing distance is replaced with the similarity between the Chinese characters to calculate a similarity between the character strings. In this method, Chinese characters are converted into numeric strings for comparison, to improve the precision of matching of the Chinese characters; and a weight of an editing distance is replaced with a similarity between the Chinese characters to calculate a similarity between character strings, so as to implement the practicability of an editing distance algorithm in matching of the Chinese character strings in the environment of the Chinese language and improve the accuracy of matching results. In addition, further provided is an apparatus for calculating a similarity between Chinese character strings based on an editing distance.
