Abstract
In this paper, we present an ontology-based visualization support system which can provide a meaningful learning environment to help e-book learners to effectively construct their knowledge frameworks. In this personalized visualization support system, learners are encouraged to actively locate new knowledge in their own knowledge framework and check the logical consistency of their ideas for clearing up misunderstandings; on the other hand, instructors will be able to decide the group distribution for collaborative learning activities based on the knowledge structure of learners. For facilitating those visualization supports, a method to semi-automatically construct a course-centered ontology to describe the required information in a map structure is presented. To automatically manipulate this course-centered ontology to provide visualization learning supports, a prototype system is designed and developed.

Summary
E-book systems are widely used together with Learning Management Systems in the education field. The existing e-learning systems, which organize the knowledge of a curriculum in a tree structure based on the textbook chapters or the class schedule, usually do not support the effective construction of knowledge frameworks by encouraging knowledge comparison because they cannot characterize essential relations between KPs. For example, in a Moodle system there are two KPs, “d” and “t”, which are located in Lesson 1 and Lesson 10, respectively. The searching will be even more time-consuming if the learner is comparing three or more KPs in a course at one time To resolve these difficulties, an ontology-based Visualization Support System for e-book users (VSSE), which uses a hierarchical map structure to manage the KPs of a curriculum, was developed in this research to encourage the cultivation of comparison skills and foster meaningful learning
