Abstract: 【Purpose/significance】In order to further grasp the macro situation of interdisciplinary, a simple and effective measure⁃
ment method is proposed, which is based on the existing classification of ESI.【Method/process】Based on relevant research, this paper
takes the ESI high-cited paper as the research object, the title vocabulary established by the title of the discipline paper as the en⁃
trance, extracts the overlapping word sequence between the vocabulary and explores its related relationship, proposes the measure⁃
ment method and makes the measurement result. Detailed analysis is conducted to analyze the cross-cutting macroeconomic situation.
【Result/conclusion】According to the obtained interdisciplinary matrix and interdisciplinary trend graph, the cross-disciplinary trend
of the subject is increasing. However, there are distinct cross-values between disciplines and the cross-disciplinary clustering occurs.
The proposed measurement method in this paper analyzes the two angles of horizontal and longitudinal to obtain the measurement re⁃
sults. This method can accurately compare the degree of intersection of various disciplines and accurately grasp the overall situation of
the intersection of disciplines.【Innovation/limitation】Based on the extraction of overlapping word sequences in the title vocabulary,
combined with word frequency analysis methods to calculate the relevance of overlapping word sequences, and use this to indicate the
degree of intersection of different disciplines, so as to measure the interdisciplinary situation at a macro level . The disadvantage is that
only selecting ESI highly cited data for analysis may overlook the emerging research directions in the discipline.
