融合关系路径与实体邻域信息的知识图谱补全方法
Incorporating Relation Path and Entity Neighborhood Information for Knowledge Graph Completion Method
摘要
Abstract
Knowledge graph provides the underlying technical support for many AI applications,including e-commerce,smart navigation,healthcare,social media,and more.However,the existing knowledge graph is usually sparse,and a large amount of hidden knowledge has not been mined,so how to complete the knowledge map has become an urgent problem to be solved.Most of the existing methods process entity neighborhood information or relationship paths indepen-dently,ignoring the importance of entity neighborhood information to the relationship path exploration process.There-fore,a knowledge graph completion method(RPEN-KGC)is proposed to fuse relational path and entity neighborhood information.RPEN-KGC consists of a sampler and an inference.The sampler provides an expert path for the inferent by randomly walking between pairs of entities,and at the same time restricts the direction of random walk with the entity neighborhood similarity comparison mechanism to enrich the expert path.By extracting the semantic features in the rela-tionship path,the inferent can infer more diverse relationship paths in the semantic space.Experimental verification is car-ried out on the publicly available NELL-995 and FB15K-237 datasets by link prediction task.The experimental results show that RPEN-KGC is improved compared with the baseline method in most indicators,indicating that RPEN-KGC can effectively predict the missing knowledge in the knowledge graph.关键词
