| With the development of Web,e-learning got a great improment,but now,it is suffering many problems as resources sharing and adaptive learning and so on.Semantic Web is proposed by Berners-Lee,for expanding semantic information on web that the computer can understand, and meeting Agent to effective access and search heterogeneous and distributed information on web.To achieve the bright vision of semantic web,the knowledge representation on web is the most fundmantal and important issues.Ontology is given a new definition by artificial intelligence:An ontology is a formal specification of a shared conceptualization.An ontology can extract relations between conceptions from a specific area of the real word,provide the shared knowledge representation,and the knowledge can be understood by heterogeneous and distributed computer systems.The realization of semantic web will facilitate a deeper realization of the shared network resources,and the research of ontology is the foundation.At present,the concern about the use of semantic web on education is in growing,and the research on specific courses is almost blank,but as important form of e-learning resources,it should be concerned.The thesis has a try on application semantic web in courses,choosing as object of research.As ontology knowledge representation is the basis technology,this thesis select the building ontology of as a starting point. Through the method of literature review, semantic analysis and some ontology building,the thesis does the try of building courses ontology of and accomplish the representation of the course with the "PMBO" (Project Management Based Ontology).In the end, it has some comformatory ananysis on finished ontology using some existing semantic search engines. |
