Otomind: A Text Mining Approach to Automatic Concept Mapping
Aida Mustapha Vinothini Kasinathan · Mathematical Statistician and Engineering Applications · 2022
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.
