Research Of Study Platform Based On Knowledge Base

With the computer technology developing rapidly and Internet is applied widely, it has changed people's study way enormously and promotes the education to tend towards network and intellectualization gradually.It has become the mainstream development direction of the international education to construct an open, resources-sharing,non-space and time limiting intelligent learning environment for learners.As a new-style teaching mode,intellectualized education has special significance to satisfy individual and social educational requirement,especially accelerating the development of domestic education project.Now intelligent tutoring system based on network can not estimate accurately study status of students and can not do an intelligent navigation effectively for study process of students because it lacks alternation and intelligence.So it results in blindness of study,can not come true individual study according to cognitive characteristic of students.Based on above problems,this dissertation researches a study platform based on knowledge base.Based on discussing the means of knowledge representation and knowledge organization in detail,this dissertation takes an arithmetic of knowledge studying to achieve intelligent navigation in study process according to the estimate of cognitive level and study ability of students.Combining with individual characteristic of students from evaluation,we can push homologous knowledge content to students. Furthermore,we can achieve individual study according to different student characteristic.The main work of this dissertation is described as below:(1) Based on the research of knowledge modeling,this dissertation takes the means of knowledge representation and hiberarchy of knowledge organization like study resource- knowledge point- knowledge tree.(2) In the process of designing student model which behaves study behavior of student,this dissertation educes an exact estimate way for the cognitive level and study ability of student about some knowledge point.(3) Based on the knowledge organization,this dissertation designs an arithmetic of intelligent navigation to select study content and form a material learning path according to the cognitive level and study ability.(4) Presenting the means of pushing homologous knowledge content to students according to individual characteristic of students and the results of knowledge reasoning.(5) Designing the knowledge base in detail and introducing a means of eliminating redundant rules in knowledge base.(6) Adopting UML to construct model in the key process and illuminating the selection of learning path according to a material application example.Furthermore, we can validate the arithmetic of intelligent navigation is effectual and reasonable or not.
