ConGraT

This repo contains code for the paper ConGraT: Self-Supervised Contrastive Pretraining for Joint Graph and Text Embeddings.

For our updated Pubmed dataset and scripts, see this repo.

What we're trying to do: We want to learn a single model of the joint distribution of text and a graph structure, where the graph is over the entities generating the text. (This latter condition is what distinguishes our case from models using knowledge graphs.) This problem occurs in a variety of settings: the follow graph among users who post tweets, link graphs between web pages, citation networks for academic articles, etc. We view it as a kind of multimodal learning, allowing models to leverage graph data that co-occurs with texts.
