Abstract

In this paper, we present our ViskiMap systems, ENWiC (EduNuggets Wiki Crawler) and Annoki (Annotation wiki), for intelligent visualization of Wikis. In recent years, e-Learning has emerged as an appealing extension to traditional teaching. To some extent, the appeal of e-Learning derives from the great potential of information and knowledge sharing on the web, which has become a de-facto library to be used by students and instructors for educational purposes. Wiki’s collaborative authoring nature makes it a very attractive tool to use for e-Learning purposes. Unfortunately, the web’s text-based navigational structure becomes insufficient as the Wiki grows in size, and this backlash can hinder students from taking full advantage of the information available. The objective behind ViskiMap is to provide students with an intelligent interface for navigating Wikis and other similar large-scale websites. ViskiMap makes use of graphic organizers to visualize the relationships between content pages, so that students can easily get an understanding of the content elements and their relations, as they navigate through the Wiki pages. We describe ViskiMap’s automated visualization process, and its user interfaces for students to view and navigate the Wiki in a meaningful manner, and for instructors to further enhance the visualization. We also discuss our usability study for evaluating the effectiveness of ENWiC as a Wiki Interface.
