1. Mentorship Map
Mentorship relationship is a special relationship between academic cooperation. To observe the mentorship of top authors of certain areas, we draw the maps of Mentorship Map (http://acemap.sjtu.edu.cn/topic/topicpage?topicID=0271BC14).
In studying the relationship between the figure, the author can observe the top authors’ mentorship and study the relationship between them, for instance, to view whom their mentors were, to observe their students’ academic achievement and whether their students are growing into a new generation of mentors and flourishing the mentorship network.
Mentorship relationship is based on the concentration, disparity, dominant degree of specificity, and other characteristics in cooperation, gained through machine learning prediction.
In studying the relationship in the figure, the nodes represent the authors, the size indicates the number of publication, the links represent the mentorship and the color represents the author in algebra from the map.
2. Mentorship Hierarchical Map
To observe the mentorship in the dimension of time, we draw the Mentorship Hierarchical Map.
Mentorship Hierarchical Map is based on the two-dimensional layout of Mentorship Map, added with the time axis. The top are the earliest scholars, and the bottom are the new scholars.
In studying the relationship between the layered graph, in addition to the scholars’ tutors and students, we can also observe the longitudinal comparison, in which historical period the top author's academic career started, which period gave birth to the authors with the most fruitful achievements, the distribution of top authors’ tutors and students, what time the students achieved more publication; can also make horizontal comparison, to compare the authors' academic achievements and the number of students of the same time.
In studying the relationship in the figure, the nodes represent the authors, the size indicates the number of publication, the links represent the mentorship and the color represents the author in what period of the history.
