[Objective] This study aims to quantitatively examine the interdisciplinary social science research with the help of machine learning technique’s automatic classification method. [Methods] We used the KNN algorithm to classify social science papers indexed by CNKI and then proposed a new method to calculate their degree of interdisciplinarity. [Results] There was significant difference among classification results of all disciplines. We also found significant correlation between the classification results and interdisciplinarity of papers. [Limitations] More quantitative research is needed to expand the present study. [Conclusions] Machine learning could effectively identify the interdisciplinary social science studies.
