Source Code for WSDM 2021 paper, "Modeling Context Pair Interaction for Pairwise Tasks on Graphs"

ConPI

This repository contains source code for our WSDM 2021 paper, Modeling Context Pair Interaction for Pairwise Tasks on Graphs.

In this paper, we propose a framework to model context interaction between target nodes in the graph. The framework contains two persepctives, node-centric and pair-centric, in which the former formulates an interaction-aware node representations for the prediction (ConPI-node), while the latter focuses on learning context pair representations directly for pairwise prediction (ConPI-pair). In addition, we proposa to pre-train a pair embedding on homogeneous graphs to further enhance the ConPI-pair model.
