The Design And Implementation Of E-Learning Platform Based On Cloud Computing

Cloud computing is the key technology to realize the online learning platform for military personnel.In the process of teaching innovation,the "Mogao"online learning of military personnel has formed a unique and new scientific research achievement.This way of learning can reflect the characteristics of online learning of officers and men in Mogao class,and it can effectively stimulate the fighting cohesion of officers and men.On the one hand,"Mogao" online learning platform can stimulate the enthusiasm of officers and men to learn.On the other hand,through the cloud computing way can easily obtain the interest of the officers and soldiers learning,and can gradually strengthen the consciousness of the group "Mu lesson" online learning vitality,and can play the essence of modern military vocational education in the process of online learning by officers and soldiers "Mu lesson".Therefore,the research of this topic has directive and guiding role.In the online learning process of officers and soldiers,there must be a dem and for mutual communication.The online comments on the platform of Mu lesson have large data features,and the information of the comments is messy and difficult to divide,and the noise is more.Some referential comments will be "lost in stone" and can not be effectively utilized.This is one of the difficulties of platform management at present.The existing online learning platform for officers and soldiers is still lack of the function of semantic analysis.In view of such problems,this paper introdu ces the semantic analysis model of mousse review for large data.In this model,the reviews are divided into three categories: content,emotion and synthesis.In view of the special semantic differences in category attributes,the focus of online learning in the content category reviews is found with the help of content word cloud analysis,and emotional words cloud analysis is used to find emotional hotspots in the online learning of officers and soldiers in emotional words,and other practical needs of officers and soldiers Online learning are found with the help of sentence analysis.From the new perspective of "Mu lesson",this paper comes to the actual work of the combination of online learning and communication with the construction of information system.This is an innovation in itself.Secondly,the system development tool,using cloud computing,puts all business instances through the designed interface service rules in the cloud computing framework.Next,and use the Hadoop Cloud Architecture to link together.In addition,the system designed in this paper focuses on the implementation of modern military vocational education management function through various ways,and transforms the abstract emerging things such as class learning into an operable and objective management information system,forming a joint force between material and spirit.In this paper,the demand analysis part mainly uses use case diagram,class diagram,use case table and other ways to analyze the learning behavior of the officers and soldiers,the video completion rate management,the interactive communication behavior analysis and the online learning and communication between the officers and the officers and soldiers in the two aspects of the business and data.At the same time,the needs of the non functional requirements are also analyzed.In the system design part,the system function design and database design are carried out for the four functional modules,which are closely related to the online learning and communication of the officers and soldiers.In the system realization and test part,the analysis of the learning behavior of the officers and soldiers in the course selection,the management of the completion rate of the learning video,the officers and the soldiers are carried out.The functions of the system are tested on the basis of modules such as line learning and communication.
