Abstract

In education, scanning through endless slides in PowerPoint presentation is highly ineffective especially for the Digital Natives due to their multi-modal learning style. In order to cater for the high volume of information emerging from printed alphabets to digital images, this study proposes a text mining approach to extract keywords from a collection of presentation slides in a similar topic. This approach is to support the existing architecture of presentation mapping, whereby the keywords extracted would then be reconstructed visually in the form of visual knowledge display. In achieving this, this study provides a general discussion of text mining technologies available and later focuses on different keyword extraction systems. Finally, this study introduces the frontier method of this field, which is presentation mining.

Keywords:
