Demonstration of the importance of system ingredients with strong similarity in cluster analysis

摘要

In this paper, we propose one method to demonstrate the importance and effectiveness of system ingredients with strong similarity in cluster analysis. As a test, we clustered 1578 SSCI journals with three different collections of journal-journal similarities, which are computed from the aggregated journal-journal citation reports of the Institute of Scientific Information (ISI). The statistical properties of the clustering results and the consistency of the results with ISI category demonstrate the importance and efficiency of those predominant system ingredients with strong similariy, and may aid the management of information for increasingly large complex systems analysis.
