Abstract: Knowledge reasoning is an important means of knowledge graph completion and has always been one of the research hotspots in the field of knowledge graph. With the development of neural network, its applications in knowledge reasoning have been paid more and more attention in recent years. The knowledge reasoning methods based on neural network have not only stronger reasoning and generalization abilities, but also higher utilization rates of entities, attributes, relations and text information in the knowledge base. These methods are more effective in reasoning. The relevant concepts of knowledge graph and knowledge graph completion are introduced, the concepts and basic principles of knowledge reasoning are indicated, and then the latest research progresses of the technology of knowledge reasoning based on neural network are reviewed. The existing problems and development directions of knowledge reasoning in the aspect of theory, algorithm and application are summarized.

Key words: knowledge graph, knowledge reasoning, neural network

摘要： 知识推理是知识图谱补全的重要手段，一直以来都是知识图谱领域的研究热点之一。随着神经网络不断取得新的发展，其在知识推理中的应用在近几年逐渐得到广泛重视。基于神经网络的知识推理方法具备更强的推理能力和泛化能力，对知识库中实体、属性、关系和文本信息的利用率更高，推理效果更好。简要介绍知识图谱及知识图谱补全的相关概念，阐述知识推理的概念及基本原理，从语义、结构和辅助存储三个维度展开，综述当下基于神经网络的知识推理最新研究进展，总结了基于神经网络的知识推理在理论、算法和应用方面存在的问题和发展方向。
