RotatE: Knowledge Graph Embedding by Relational Rotation in Complex Space

We study the problem of learning representations of entities and relations in graphs for predicting missing links. The success of such a task relies on the ability of modeling and inferring the patterns of (or) the relations. In this paper, we present a new approach for knowledge embedding called RotatE, which is able to model and infer various patterns including: symmetry/antisymmetry, inversion, and composition. , the RotatE model defines each relation as a rotation from the entity to the target entity in the complex vector space. In addition, we a novel self-adversarial negative sampling technique for efficiently effectively training the RotatE model. Experimental results on multiple knowledge graphs show that the proposed RotatE model is not only, but also able to infer and model various relation patterns and outperform existing state-of-the-art models for link prediction.
