Abstract： [Purpose/significance] In order to improve the effect of content-based citation analysis, this paper summarizes the related research on citation object at home and abroad, and provides reference for citation content analysts.[Method/process] By investigating the related research on citation object at home and abroad, this paper reviewed the definitions of the citation object, classification systems, application fields and automatic identification, summarized the current research on the citation object and put forward the future development direction.[Result/conclusion] The citation object evaluates the contribution and utilization value of academic research from the semantic level, which adds an important dimension to the citation analysis method. The research on citation object needs to be deepened in three directions:theoretically, to strengthen the research and analysis of multi-dimensional citation object features; technically, to explore the automatic identification methods based on large-scale corpus; application, to try to provide scientific research evaluation services based on citation objects.
