睡美人文献识别方法研究进展

Purpose/significance] Sleeping Beauty (SB) refers to a wealth of published literatures with great scientific value. This paper makes a thorough review on the methods to identify SBs at home and abroad, and aims to provide reference for future research in this field.[Method/process] The identification methods are divided into four categories. Their theories, criteria, advantages and limitations are summarized. By comparing the Four Rules, the paper points out the application scope of each.[Result/conclusion] From subjective parameter to objective indicator, and one citation curve to multiple curve, identification methods of SBs have been enriched. The future study on SBs identification should focus on the redefinition of depth of sleep and the unification of existing methods. In addition, the qualitative and confirmatory research on the predictive value of SBs citation should also be considered.
