Embedding models for knowledge graph completion

A brief introduction to TransE, TransH, TransR and CTransR models

There are several definitions of knowledge graph (KG) in different fields of study. In this article, we define KG as a graph where each node is an element of an entity space E and each edge is an element of a relation space R. The detailed definitions of E and R are domain-specific: for instance, in social networks, E is a set of people and R is a set of different types of relationship (relative, friend, partner, stranger).
