This paper studies the h-index-based academy credit evaluation based on fractional theory. The ACE model based on h-index was proposed and implemented. Learning from many study of academic performance evaluation, the paper proposed an ACE model emphasizing the credit from academic experts, with some new methods and indictors such as large-scale h-index extracting approach, citation recommendation analysis approach and z-index indicator. To apply the new model of ACE in real academic performance evaluation, related software was developed. The empirical study shows that the h-index-based academy credit evaluation based on fractional theory can achieve better performance than the traditional algorithm in academy credit evaluation.
