The Research Of The Scaffolding Instruction Based On The Prerequisite Concept Of Intelligent Identification

With the rapid development of today’s social network information,information Resources diversification,there is a real problem:Fragmentation of knowledge makes learning a serious burden,Challenges for the E-learning teaching.In order to integrate knowledge,find the association between the knowledges, reduce the burden of learning learners,the study of artificial intelligence and natural language technology methods which extract the associated text resources of knowledge and knowledge between.By vector space model(VSM),parser,algorithm design,extract intelligently correlation exists between concepts and with the scaffolding instruction,theoretical basics of navigation,push resources for learners in knowledge construction process,help learners to understand the knowledge, the initiative to build knowledge structure.The main innovation of this study is to obtain the relationship between the concepts from text,and achieve visually knowledge navigation,While push resourcesand explanations for the concepts from text and navigation knowledge.This paper is divided into seven chapters, the first through literature, summed up Introduction, include: research background,significance and status.And focus on defining the association between the concept and the concept of this article.Finally, it details the content of this paper.Based on the foundation, it focuses on the key technologies scaffolding instruction and theory used in this study. Then focuses on the research ideas,expound in detail the artificial extraction experiments of prerequisite concept. And sum up the method ofartificial extraction experiments of prerequisite concept,to prepare for the pre-extraction algorithm behind the concept.Chapter Four:It is the focus of this research study,this chapter describes in detail the concept of pre-extraction method.Propose combination of artificial intelligence techniques,natural language processing methods mining areas of conceptual terms, pre-concept, conceptual relations,and throughout the author’s ideas and theoretical algorithm design.By the algorithm to achieve the above preconditions concept in theory supported by scaffolding instruction knowledge organization.The implementation process is divided into three parts:forest converted into binary storage method list,teaching bracket,Scaffolding teaching system based on the prerequisite concept implementation.In which the author combines practical application examples of the various stages of the design algorithm is described and the final algorithm depth analysis and discussion.Study design teaching stent push research resources based precursor of the concept.This chapter on performance prerequisites concept extraction algorithms and experimental evaluation,artificial extraction and detection algorithms to extract the precursor of the concept of precision and recall rates.The experimental results were analyzed and summarized.Finally:Summarize this research,made insufficient research existsand propose further research work.
