[Purpose/significance] This article proposesa method of determining scope of word set in co-word analysis based on word frequency, number of words, cumulative word frequency in proportion. It tries to solve the problems of existing research methods, including excessive dependence on judgment from experience and key words with frequency of "1" to provide a more standardized and scientific method and practice. [Method/process] This method fully considers the actual distribution characteristics of the word set and classifies the words or phrases into three areas:high, middle and low frequency area. At the same time, it chooses the high and middle frequency words as the object of co-word analysis. [Result/conclusion] This method isproved to be used to select the appropriate range of the word set effectively by comparing with other methods and empirical analysis in the specific field, which can be used for reference in the future.
