Slide presentations have become a ubiquitous tool for business and educational purposes.Instead of starting from scratch, slide composers tend to make new presentation slides by reusing materials from existing slides.Understanding how slide elements are copied from one presentation file to another and how presentation files are related to each other are difficult tasks.In this paper, it is investigated the management of multiple presentation files based on reused slide elements.Techniques are developed to detect textual and visual elements that have been reused across multiple presentation files.Interactive visualization methods are proposed to facilitate understanding the process by which these elements are reused and the relationship between the files that use them.A system with a user-friendly interface is designed, based on which experiments are performed to evaluate the effectiveness of the proposed methods.
