Modelling Knowledge Learning Based on Extended Topic Map

With the rapid growth of knowledge resources and increasing individual learning demands of users, it has been becoming more and more important to establish a kind of more comprehensible, more available and more application-oriented knowledge learning mechanism. By studying the critical factors in knowledge learning, the paper firstly proposed a novel concept of extended topic map for knowledge learning, it embodies the multi-level, multi-granularity and inherent relevant characteristics of knowledge and realizes knowledge visualization display. And then we defined multi-layer Service-Oriented knowledge architecture with the extended topic map as infrastructure. Additionally, a system framework of the knowledge learning is designed and implemented. Finally, a demonstration is given to display the knowledge learning based on extended topic map.
