Large Scale Knowledge Graph Representation Learning

Résumé

Abstract The knowledge graph emerges as powerful data structures that provide a deep representation and understanding of the knowledge presented in networks. In the pursuit of representation learning of the knowledge graph, entities and relationships undergo an embedding process, where they are mapped onto a vector space with reduced dimensions. These embeddings are progressively used to extract their information for a multitude of tasks in machine learning. Nevertheless, the increase data in knowledge graph has introduced a challenge, especially as knowledge graph embedding now encompass millions of nodes and billions of edges, surpassing the capacities of existing knowledge representation learning systems.In response to these challenge, this paper presents DistKGE, a distributed learning approach of knowledge graph embedding based on a new partitioning technique.In our experimental evaluation,we illustrate that the proposed approach improves the scalability ofdistributed knowledge graph learning with respect to graph size compared toexisting methods in terms of runtime performances in the link prediction task aimed at identifying new links between entities within the knowledge graph.
