Research On The Construction And Application Of Knowledge Map Of Physics In High School

With the rapid development of the Internet,big data and artificial intelligence technologies have brought many changes to our life and study,and the education industry has gradually changed from the traditional way to modern intelligent education.Knowledge mapping,as a branch of artificial intelligence,has also begun to be applied in the education industry.Knowledge map is a kind of structured semantic knowledge base,which has strong structure expression ability and ontology semantic description ability,and has great advantages in knowledge representation,open sharing and accurate retrieval.Based on the study and analysis of the characteristics of senior high school physics,this paper proposes the process of constructing the map of senior high school physics knowledge based on ontology,and designs and develops an online intelligent learning system.The specific research is as follows:First of all,this article uses " seven steps" to build ideas.And it's through the research of ontology modeling and the analysis of high school physics knowledge structure.It puts forward physical discipline ontology construction method,which is based on the high school physics teaching outline,to mark of electronic teaching materials and to extract knowledge instance.And it completed the construction of high school physical science ontology.Then,it extracts network data through web spider and conducts entity recognition,relation extraction and attribute extraction on network data,which completes and optimizes the constructed knowledge structure,and visually displays the knowledge map.Finally,an online intelligent learning system is developed for application in physics teaching,which is based on the constructed map of high school physics subject knowledge.The platform supports knowledge query,structure diagram display and exercise recommendation,which is conducive to promoting the learning of physics knowledge.
