Abstract: Abstract Previous studies on scientific literature rarely considered discrimination, i.e., the extent to which the content of some research is different from that of others. This paper contributes to the quantitative methods used for the research on the discrimination of article content via the proposal of the article discriminative capacity (ADC). Academic articles included in the Chinese Social Sciences Citation Index (CSSCI) in the discipline of Library and Information Science (LIS) are used as research objects. First, the most suitable text representation model is chosen to better represent the content of articles, thereby improving the performance of ADC. Then, in-depth quantitative analyses and evaluations of the articles from the perspectives of the source journals, publication years, authors, themes, and disciplines are conducted in conjunction with the ADC. The results demonstrate that the combination of the ADC with the BERT model can better identify a single article with high discriminative capacity. Articles in the fields of Information Science and Cross-LIS are found to have relatively low average ADC values. In contrast, articles in the fields of Library Science and Archives Science have high average ADC values. Articles with high ADC values have diverse themes and distinctive keywords, and can reveal new methods and promote interdisciplinarity. On the contrary, articles with low ADC values have similar research themes, and favor traditional, commentary, and conventional research. Moreover, scholars with high discriminative capacity are more willing to explore new fields, instead of being confined to traditional LIS research. This work may help promote the diversity of academic research and complement the evaluation system of academic articles. One major limitation of this study is that it only used data from Chinese databases.
