Conventional network representation learning (NRL) models learn low-dimensional vertex representations by simply regarding each edge as a binary or continuous value. However, there exists rich semantic information on edges and the interactions between vertices usually preserve distinct meanings, which are largely neglected by most existing NRL models. In this work, we present a novel Translatio...

We consider two propagation models: the social conversion mechanism and the self conversion mechanism, corresponding respectively to the endogenous and exogenous factors. A novel concept, the product-conversion graph, is proposed to characterize the interplay among competing products. A...
