Architecture And Application Of Service-Oriented ITMS Based On MAS

This thesis discussed the conception and status quo of ITS.It analysed traditional ITS, service oriented architecture and agent technology.It laid academic foundation for AB-ITMS. With the primary clue of "knowledge services of service oriented architecture",it completed the aichitecture designation of AB-ITMS,realized the adaptability study and intelligent tutoring manage, resolved the question of low intelligent,weakly mutuality,real-time for AB-ITMS.The researchful emphasis of this thesis included multi-agent technology, object-oriented modeling of AB-ITMS,dynamic integration of software service and knowledge services.Multi-agent cooperatively completed complicated intelligent tutoring and managing.It changed AB-ITMS from passive tutoring to active tutor ing, attracted attention the individuality and cooperative demand of the learner in the tutoring strategy and management.Object-oriented modeling of AB-ITMS included learner,teacher and field knowledge.The material character layer and the general character layer constituted learner modeling.According to learner character,it builded the general character by faint and general evaluation algorithms for recessive tutoring knowledge.Teacher modeling formed an integrated tutoring model via cooperative agent,presented the reasoning algorithms of tutoring rule and tutoring strategy.According to field knowledge configuration and tutoring strategy,adopted tutoring content,structural knowledge,process knowledge and general knowledge,field knowledge modeling constructed the dynamic model and the static model of field knowledge.Service AB-ITMS defined four service style of knowledge services,tutoring manage services,tutoring strategy services,tutoring application mode services.In order to resolve the rich custom of web services, AB-ITMS adopted the integrated service of SOA,realized the dynamic join,exit and integration of the software services.AB-ITMS of oriented knowledge services is a software system of information services,processed information and resource in knowledge and content layer,based on commendatory,searching and mutual mode,afforded active information and knowledge resource service.AB-ITMS took the core of intelligent tutoring,adopted the technology of MAS,CSCL,DAL,XML and so on,integrated the activity of leraner,teacher,tutoring manager,connected the various service in the intelligent tutoring,changed the single service into intelligent knowledge service,realized individuation,adaptability and service AB-ITMS finally.
