Structure-Based Algorithm for Presentation Mapping in Graphical Knowledge Display

Abstract

Abstract-Slide presentations have been widely used in current teaching and learning process. While text-laden slides might give a comprehensive feel over the materials, information overload might end up the learner getting confused in the middle of presentation. On the contrary, slides full of key points are not useful without the presenter. The objective of this research is to improve the teaching and learning process by transforming the slide content into a graphical knowledge display. A structure-based algorithm for presentation mapping is proposed to extract the keywords from each slide and to model into a mind map via web interface. 

Otomind: A Text Mining Approach to Automatic Concept Mapping

“…To address this issue, this paper presents OtoMind, an automatic mind map generator that extracts and builds the mind map directly from the PowerPoint presentation slides. This tool provides an interface for the users to browse for the PowerPoint file (.ppt or .pptx), subsequently read and analyze the slides, and generate a mind map with the central theme and content coming from the all the slides in the presentation [17]. This tool primarily uses a text mining approach, specifically keyphrase extraction along other natural language processing tasks.…”
