Learning Navigation Map on Ontology

The paper utilizes semantic Web and knowledge service technologies to construct a subject-oriented learning navigation system used in middle school education. The system inherently builds a knowledge base by ontology to store the relationship of subject knowledge points to learning resource and relationship between knowledge points , displays the reticulated structure of knowledge (navigation map) formed by visualizing knowledge base, and aggregates corresponding learning resource of knowledge point to enable learners practice their learning process according to the navigation map. The thesis build ontology for navigated learning to achieve pragmatic learning navigation, there are several advantages for this innovative research: the reticulated structure of knowledge in a certain subject could be displayed briefly and straightforward; the system could recommend related and further study materials for learners and intelligently discover the weak knowledge points of learners according to automated reasoning on knowledge base. The system also provides an interactive environment for both teachers to edit the knowledge structure and learners to study. As the most popular knowledge model, we mainly discusses the establishment of semantic knowledge Web, model of the knowledge base, knowledge storage for knowledge points in junior and senior schools, and the realization and utilization of the ontology-based navigation map.
