Skeleton Generation for Presentation Slides Based on Expression Styles

With the advent of PowerPoint and Keynote that can effectively create attractive presentation slides, people can use them to exchange and discuss ideas together. However, because it is necessary to prepare many slides to enable audiences to understand the content, authors need to prepare the best possible slides. Our skeleton generation method is designed to help authors to prepare slides with ease by constructing slide layouts based on the expression styles that the level positions of words expressing their role in slides from the text in the textbooks they use. By analyzing the role of the words in the slides, our method can then extract the differences between the important elements in both the texts and slides. To generate skeletons for slides from target texts in a textbook, our method derives the expression styles of the words from pre-existing texts and their slides. Finally, it generates slide skeletons by using the same expression styles of the corresponding words from the target texts arranged in slides, which are the same as the layouts of pre-existing slides. We also present the results of an evaluation of the method’s effectiveness.
