| Abstract: | Purpose/significance] In order to efficiently aid researchers to identify research hotpot, this paper aims to explore theoretical basis and practical guidance of data cleaning in the process of identifying research hotpots based on keywords co-occurrence. Method/process] On the basis of literature research, it firstly defines the conception and the objects of data cleaning. Then it analyses the reasons and influences of dirty data. Finally, it proposes the procedures of data cleaning, which is verified by empirical research method. Result/conclusion] The result indicates that the procedures of data cleaning which are proved to be feasible can increase the accuracy of identification of research hotpot. |
