Abstract


With the rapid development of Internet , online education system has been an important part of the Internet . With the concept of lifelong education is deeply rooted in the hearts of the people , more and more people learn on the web , and has become an indispensable tool for people to learn life . However , the existing E-learning systems are the learning resources statically on the web , it is difficult to adapt to different levels of students , can not be based on the student 's interest , knowledge the level dynamically organizational learning content , learners personalized service. At the same time , the existing E-learning system , the establishment of very difficult to get rid of the lack of semantic understanding of defects in traditional information retrieval techniques search engine that provides users with information accuracy , comprehensiveness is less than satisfactory . Therefore, the E-learning system adaptive learning , to provide users with personalized service is the traditional E-learning system problems to be solved . In order to solve the defects of the traditional E-learning to adapt to the user's needs , With the help of the body in the description of the advantages of the knowledge and semantic relations and gradually improve the data mining technology was proposed based on the Semantic Web mining techniques , and this applies to the E- learning system . The in-depth study and discussion on the theory of ontology technology , design and initial realization of a way to provide personalized service network teaching system . Description of the body in the system description language as a W3C standard OWL ontology language , RDF / RDFS semantic annotation of data as a resource Markup Language , by Jena as a tool to achieve a specific domain knowledge ontology reasoning and data mining query successfully achieve semantic information query tool .
