Figure 4
From: Scientific success from the perspective of the strength of weak ties
Average asymmetric tie strength of a scientist. The figure presents ego-networks of three different scientists (egos) with the same number of co-authors \(k_i=3\) and publications \(p_i=3\), but with different patterns of collaboration. On the left scheme (a), each of the three publications has only two authors; on the central scheme (b), two publications were written by a team of three and one by a team of two; in the scheme on the right (c), all publications involved the entire ego-network of a scientist. In each of the presented cases, the ego’s average asymmetric tie strength is different. Its value increases from the left diagram to the right, exactly in the same way as the intuitively understood social role of collaborators, on which depends not only the ego’s productivity but also integrity of his/her research group.
