The knowledge graph and its related technologies are important concepts for the development and application of artificial intelligence.The knowledge graph,together with the concept of "explanatory intelligence",is being evaluated between the start-up period and the high fever period of innovation,and is expected to be widely applied in the next 5 to 10 years.All industries and enterprises at home and abroad have cases to introduce knowledge graph into the technology stack,or directly in the form of projects to apply and promote intelligent products mainly based on knowledge graph.Based on the actual needs of domestic institutions,this paper implements a practical application of knowledge graph in the field of education and teaching,and expounds the complete process and method of its completion of productization in detail.First of all,this paper has done a lot of research on the course outline information retrieval system,mainly for the complete construction process and commercial application of knowledge graph,and has done a lot of scene research.It has investigated the technical concept principle,domestic and foreign business application cases,knowledge graph classification and graph display forms,graph storage and query methods,and product data processing related to the expansion of the field This paper analyzes the application of knowledge graph in text information retrieval,similar information query and recommendation.Secondly,on the basis of system architecture design,four modules are designed in detail,which are knowledge representation and modeling,data cleaning,knowledge acquisition,graph query and graph search.In the knowledge representation and modeling part,data entities are described abstractly,data patterns are established,and schema is designed for the system;in the data cleaning module,multiple data are captured through data mining,natural language processing and other technologies,and the captured data is further cleaned to ensure the accuracy of the data;in the knowledge acquisition module,knowledge extraction,fusion In the input step,unstructured and semi-structured data are processed structurally,and the data is stored as knowledge type in the form of graph;graph query and graph search are based on knowledge graph,and graph database is used to provide search and query services.Finally,according to the user's interaction habits,the interface of the platform is designed to facilitate the management of managers and the use of users.Based on the technology of knowledge graph,this paper realizes a practical application in the field of education with a relatively new way of information processing and integration,provides a more accurate and rapid information retrieval service,helps users better complete the information retrieval,and improves the user experience.
