Abstract:

[Objective] To comprehensively, intuitively, and efficiently depict and compare the characteristics of scholars' scientific research activities, this article proposes a temporal scholar portrait visualization method that supports comparative analysis. [Method] The visualization method of temporal scholars' portraits is based on the Sun metaphor and citation network, with a time dimension as the main thread. It combines basic information such as the number of scholars' published papers over the years, the affiliation of the scholars, the topic of the papers, the influence of the papers, cooperative scholars, and cooperative institutions with deep-seated information such as changes in research interests, the breadth and depth of the research topic, etc., enabling decision-makers to quickly and comprehensively grasp the similarities and differences of different scholars. [Results] This article uses a dataset from the field of visualization to design and implement a temporal scholar portrait visualization system TSPVS. [Limitation] However, currently the system only includes paper data from the visualization field, and further introduction of paper data from other fields will be made in the future. [Conclusion] Through three cases in the visualization field paper data, it is demonstrated that TSPVS can meet the analysis needs, depict important features and significant changes in scholars' research careers in one page, and support comparative analysis of the main characteristics of different scholars.
