The graphical model for TIR is given in Figure 1, and the generative process is detailed in the following pseudocode: • Sample an influence weight, • For each cited document c ∈ C (d) • Draw edge influence weight, • Assign a prior over topics via • Sample a distribution over topics, The TIR model can be viewed as an adaption of the Dirichlet-multinomial regression (DMR) framework of Mimno and McCallum (2008) to model topical influence.
