Abstract

We study the extent to which online social networks can be connected to open knowledge bases. The problem is referred to as learning social knowledge graphs.We propose a multi-modal Bayesian embedding model, GenVector, to learn latent topics that generate word and network embeddings.GenVector leverages large-scale unlabeled data with embeddings and represents data of two modalities — i.e., social network users and knowledge concepts — in a shared latent topic space.Experiments on three datasets show that the proposed method clearly outperforms state-of-the-art methods. We then deploy the method on AMiner, a large-scale online academic search system with a network of 38,049,189 researchers with a knowledge base with 35,415,011 concepts. Our method significantly decreases the error rate in an online A/B test with live users.
