Then, I will offer detailed discussions of the respective modules one by one. First, the cascade is defined as C of s and t. It is a sequence of forwarding behavior denoted as $u_n$ and $t_n$. For each participant $u_n$ , its historical action sequence consists of many tuple of $(m_n^K,\tau_n^K)$, where $\tau_n^k$ is the timestamp when individual $u_n $ posts or forwards the historical message $m_n^k$. The historical action sequence represents other messages that user $u_n$ has forwarded before participating in cascade $\mathcal{C}$. |
