It is important to construct models about a domain for understanding the domain. In previous works, we developed a learning support system for learning by structuring of knowledge structure with concept map. The system required learners to construct layered concept map and provide error visualization based on the concept map. In this research, we expand the error visualization based on several concept and link which are used in Ontology engineering. In particular, this paper show various famous errors when the ontology is described and study error visualization for the errors.
