Generating Slide Skeletons based on Expression Styles for Presentation Contents

By using PowerPoint or Keynote that can effectively create attractive presentation slides, a presentation-based communication environment can now be created in which people can use these presentation slides 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 of words from the text in the textbooks they use. To do this, we analyze the expression styles of the words presented in the slides; our method can then extract context-role of the words by the differences between the words in the texts and their 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 derived 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. Keyword e-Learning, Skeleton generation, Expression styles, Slide making support
