Interest-transition network and transition probabilities.
(a–c) For the three individuals represented in Figs. 1(a–c), the respective transition networks, where nodes correspond to distinct interests, a self loop represents the dwelling time in the same interest category and the weighted links characterize the interest transitions. A few highly frequently visited interests are marked. (d–f) Truncated fat-tailed in the rank distribution: fr ∝ r−γ exp (−r/S), where the fitted values of the exponent γ and the numbers of interests are (γ, S) = (0.89, 24) (panel (e), Taobao) and (γ, S) = (1.39, 44) (panel (f), MPR) (The dashed line in Fig. 3(d) is for eye guide). (g–i) Two-dimensional representation of the interest-transition probabilities for the three networks in (a–c), respectively. The probabilities are represented on a logarithmic scale; see side bars.
