Abstract

The purpose of knowledge graph completion is to predict the missing parts in the triplet and make the knowledge graph complete. In view of the fact that the link prediction methods based on neural network and other models ignore the association information between entities, resulting in the model can't cover the inherent hidden information in the local neighborhood around the triple. Aiming at this problem, this paper proposed a method combining graph attention mechanism with predicate perception. Firstly, it defined a relational embedding matrix to describe the relationship between entities in the neighborhood of any given entity by using graph attention mechanism. Secondly, it introduced predicate to enhance the semantic understanding between entities, and constructed the attention value calculation formula based on predicate embedding vector to effectively measure the strength of semantic connection between entities. In addition, it used the edge relationship between entity neighbors to predict the direct relationship between multi-hop entities to complete the knowledge graph. Experimental results on WN18RR, Kinship and FB15K datasets show that the proposed method can effectively improve the prediction accuracy of triplets.
