[Purpose/significance] It is of great importance to study the law of uncitednessfrom content differences, which is not only the important content in studying uncitedness phenomena, but helps to expand the boundary of citation content analysis. [Method/process] CSSCI was selected as the source database, and library and information science was chosen as the sample source.According to the features of the h index, 200 scholars were selected randomly as samples, and their related data, recorded in CSSCI from 1998 to 2015, were downloaded. All the collected data of library and information science from 1998 to 2015 were downloaded, and their relevant data about cited papers and highly cited papers were extracted.Taking 6 years as time window, the papers cited in 1 to 3 years were defined as cited papers, and the others as uncited papers.The key words of uncited papers, cited papers, all discipline papers and highly cited papers were taken and listed according to keyword frequencies from high to low, first 50 keywords were selected to be keywords vector, and their inner product, Euclidean length and cosine similarity were calculated respectively. [Result/conclusion] The results have showed that: the research content of library and information science has been probably stable at the beginning of 21st century; the content similarity between uncited papers and all discipline papers, cited papers, and highly cited papers are lower, which means the research content has a significant effect on uncited papers.
