Otomind: A Text Mining Approach to Automatic Concept Mapping

Despite the linear use of PowerPoint presentation slides in classroom and lecture halls, the brain works primarily with key concepts that it links and integrates. This is a big contrast from the typical student behaviour of reading or memorizing the slides.This paper presents a new system that automatically generate a mind map based on a set of keywords and keyphrases extracted from PowerPoint presentation slides. The system takes a text mining approach and relies on a keyphrase   extraction algorithm to extract the keywords and keyphrases. Survey results reflect a rising need of such application as part of educational technologies and the potential benefits are observed and discussed.
