Figure 1. Schematic representation of local and global attachments of the model.

Figure 1

Vertical lines represent the time lines of users. Horizontal solid and dashed lines represent events occurred and to be occurred between nodes, respectively. The number of events on a link defines the weight of the link. A. Local Attachment (LA): The node Inline graphic has a chance to interact with node Inline graphic at time step Inline graphic only when there exists a temporal path connecting Inline graphic and Inline graphic through their common neighbor Inline graphic within time window Inline graphic. B. Global Attachment (GA): The isolated node Inline graphic has a chance to interact with a randomly chosen node Inline graphic.
