Visualization with a hierarchy of mathematical knowledge structure, assist learners in understanding mathematics. We are developing a method which constructs a hierarchy of mathematical knowledge by using hyperlink analysis in our mathematics e-learning site. Hierarchy is calculated by an adjacency matrix. 

This paper focuses on ontology construction as a foundation for knowledge representation. We present here the processes of knowledge acquisition, analysis, and representation using a conceptual modeling tool, the Inferential Modeling Technique (IMT), as a basis for ontology construction. To illustrate the knowledge modeling process, we apply IMT for knowledge analysis in the domain of petroleum...
