Abstract

The learning process for a user becomes seriously restrictive in trying to discover the relationships between concepts and in searching for a part of concept (called an object) such as a solved example illustrating the concept or the application of the concept. This paper presents the theory for building relational graph that depicts how concepts are linked to each other. By selecting to zoom on a particular concept, the user's view changes to conceptual graph where he can view and access all the objects related to a particular concept. Rule-based algorithms are presented to identify objects of a concept, to determine concept boundary and to build the trees. The lecture material on Algorithms course from MIT is used for experimentation of the ideas. In addition to efficient searching for desired topic, the system also enhances the understanding and the learning of the user.
