Knowledge mapping construction method for subject education resources

Abstract

The invention discloses a knowledge mapping construction method for subject education resources. The method comprises the following steps that 1, information of entities and relation information in the subject education resources are extracted; 2, cleaning integration is carried out on the information, information redundancy and wrong information are eliminated, thereby ensuring the quality of theinformation; 3, classification and semantic association are carried out on the information to form a knowledge representation form of 'entity-relation-entity' triples, and a visual tool is utilized to construct a subject resource knowledge mapping; 4, tacit knowledge is further excavated through a knowledge inference, evolution and update are carried out on the knowledge mapping, thereby enriching and extending a knowledge base. The knowledge mapping construction method for the subject education resources has the advantages that the knowledge mapping for constructing subject resources is provided, the continuity and consistency of subject resource content are achieved, the systematized and systematic subject knowledge mapping is provided for learners, thereby promoting the practical application of a knowledge mapping technology in the fields of education resource management, information retrieval, knowledge recommendation and the like.

Description

technical field [0001] The invention relates to the application technology of a Chinese knowledge base, in particular to a method for constructing a knowledge graph oriented to subject education resources. Background technique [0002] With the rapid development of information technology, learning resources of various subjects on the Internet are becoming more and more abundant, which solves the problems of large-scale users simultaneously learning online, obtaining teaching services, and sharing educational resources to a certain extent. At the same time, it also creates conditions for personalized learning. [0003] However, in the existing subject learning resource system, there are only simple resource storage and retrieval functions, which cannot provide a more effective way for the expression, organization, management and utilization of massive, heterogeneous and dynamic teaching resources on the Internet. How to make The degree of connection between resources is high...

Problems solved by technology

[0003] However, in the existing subject learning resource system, there are only simple resource storage and retrieval functions, which cannot provide a more effective way for the expression, organization, management and utilization of massive, heterogeneous and dynamic teaching resources on the Internet. How to make The degree of connection between resources is higher, and it is closer to human cognitive thinking. To solve the problem of "knowledge trek" for learners, we need to find a suitable method
