Design And Implementation Of Visualization System For Nursing Knowledge Graph

Today,the aggravation of China’s aging problem has promoted the rise of the home care industry.Introducing computer technology to old-age care filed can promote the informationization of the old-age filed,help allocate the old-age resources more rationally,and alleviate the problem of shortage of pension care resources.Combined with the above background,this paper designs and develops a nursing knowledge map visualization system to help nursing staff integrate the distribution of nursing resources and improve the work efficiency of nursing practitioners.The main work of this paper includes the following points:(1)Define the visualization tasks of the system,analyze the requirements of the system,and divide the system into user modules,several visual view modules and several functional modules such as the map visualization editing module.The system is designed based on BS architecture and layered architecture,and the functional architecture of the system is described in this paper.(2)Detailed design various views and human-computer interaction processes in the system visualization module.Use FR algorithm,RT algorithm and other visualization algorithms to implement the system visualization view based on D3.Describe the business process,front-end interaction and data processing details of each functional module of the system.Each module of the system is realized.(3)The black box test is performed on the system based on the real machine environments,which makes sure that the system passes all test cases to ensure the completeness of the system functions.Verify the system based on several expected scenarios with experiments like using the system to make nursing measures visualization recommendation and supplement the knowledge graph data.
