Evaluation of coloring methods of characters for presentation slides

This paper experimentally and quantitatively evaluates three methods of coloring words on presentation slides. These are the method using term-frequency (TF) and inverse document frequency (IDF), the one focusing on the words in the “Conclusion” slide and textboxes (WCT), and the one using TF and WCT. These methods try to identify important words in a presentation slide. After the important words are identified, they are colored with the “Accent color,” which is for the place where we want to emphasize. It is shown that the TF-WCT method is more precisely color the words than the other methods, and that it could select the same words as those the subject selected at the very best selection.
