Understanding Presentation Document with Visualization of Connections between Presentation Slides

Recently, there has been increasing opportunities to utilize presentation documents consisting of slides as learning contents via the Web services such as SlideShare. In learning a presentation document, the learners generally need to select a number of slides from the document, which describe what they want to learn or should learn. However, it is not so easy to find out the slides to be learnt since what each slide represents is not concisely stated and the connections between the adjacent slides are not explicitly expressed. They accordingly take more time for learning, and finish learning with incomplete knowledge. In order to address this issue, this paper introduces a model of how to understand the presentation document. We also propose a map for visualizing the logical connections between the slides, which follows the model. This map helps learners identify the sequence of slides to be learnt from the presentation document, and allow them to comprehend the structure embedded in the document in shorter time.źIn addition, this paper reports a case study for generating the visualization map.
