| dc.description.abstract | As artificial intelligence in the big data era,knowledge graphs are widely used in many fields.Knowledge graphs gene-rally suffer from incompleteness and sparsity.As a sub-task of knowledge acquisition,knowledge completion aims to predict mis-sing links from known triples in the knowledge base.However,existing knowledge completion methods generally ignore the auxi-liary role of entity type jointly with neighborhood information,which can improve the knowledge completion accuracy.There are other problems such as feature information closely encodes into the objective function,and integration operations depend on the training process highly.To this end,a Bayesian rule-based knowledge completion method with hierarchical attention is proposed.Firstly,it regards entity type and neighborhood information as hierarchical structures,groups by relationship.It calculates each type information's attention weights independently.Then the entity types and neighborhood information encoding are regarded as the prior probability.The instance information encoding as likelihood probability.The two are combined according to the Bayesian rule.Experimental results show that the mean reciprocal rank(MRR ) metric in the FB15k dataset improves 14.4% over ConvE and 10.7% over TKRL.The MRR metric in the FB15k-237 dataset improves 2.1% over TACT.In the FB15k,FB15k-237 and YAGO26K-906 datasets,its Hits@1 reaches 77.5%,73.8% and 95.1% respectively,which demonstrates the introduction of type information and neighborhood information with hierarchical structure can embed richer and more accurate descriptive information for entities,and thus improve the accuracy of knowledge completion. | |
