Research On The Construction And Application Of Subject Knowledge Map Of Data Structure Course

With the development of computer information technology,distance education and online teaching form of computer-aided teaching activities in our learning life gradually become common,knowledge acquisition channels compared with traditional teaching also become rich and diverse.Smart education technology based on big data and artificial intelligence technology is a hot research topic,and has achieved some results in the field of basic education.Knowledge mapping is a kind of semantic network,which is composed of entity nodes,entity attributes and the relationship between entities.It is the key technology foundation of cognitive intelligence.Knowledge mapping technology in the field of education is generally applied to the construction of vertical domain knowledge mapping based on the subject knowledge system.By mining,collecting and summarizing the concept hierarchical relationship,pre and post order relationship and association relationship between the subject knowledge points,we can organize the construction of subject knowledge mapping,and help students to master the course knowledge framework,access knowledge points and discover knowledge connection between knowledge points can improve learning efficiency.In the computer professional curriculum,"data structure" course is a core introductory professional course for students,which plays an important role in the whole professional curriculum teaching practice.Because the course is theoretical and requires certain logical thinking ability,it is easy for students to encounter the situation that it is difficult to understand and master many abstract and complex concepts in the learning process.Therefore,with the help of deep learning and natural language processing technology,this paper applies Bi-LSTM-CRF and TextCNN algorithm to analyze and integrate the text resources of data structure course,so as to provide convenience for knowledge learning and knowledge reuse of data structure course.This paper starts with the research progress of educational resources informatization construction and subject knowledge base construction at home and abroad,Secondly,it summarizes the related theories and technologies involved in the construction of knowledge map,and then introduces the process,methods and related algorithms of building knowledge map of data structure course.Finally,it describes the process of building knowledge map of data structure course with the idea of software development.
