Many studies have analyzed “direct” partnerships in co-authorship networks. On the other hand, the global network structure,
including “indirect” links between researchers, has not yet been sufficiently studied. This study analyzes researchers' activities
from the viewpoints considering their roles in the global structures of co-authorship networks, and compares the co-authorship
networks between the theoretical and application areas in computer science. The modified HITS algorithm is used to calculate
the two types of importance of researchers in co-authorship networks, i.e., the importance as the leader and that as the follower.
