Chinese Pinyin input method is very impor- tant for Chinese language information pro- cessing. Users may make errors when they are typing in Chinese words. In this paper, we are concerned with the reasons that cause the errors. Inspired by the observation that press- ing backspace is one of the most common us- er behaviors to modify the errors, we collect 54, 309, 334error-correctionpairsfromareal- world data set that contains 2, 277, 786 user- s via backspace operations. In addition, we present a comparative analysis of the data to achieve a better understanding of users’ input behaviors. Comparisons with English typos suggestthatsomelanguage-specificproperties result in a part of Chinese input errors.
