Tell me why! ain't nothin' but a mistake? describing media item differences with media fragments uri and speech synthesis

We have developed a tile-wise histogram-based media item deduplication algorithm with additional high-level semantic matching criteria that is tailored to photos and videos gathered from multiple social networks. In this paper, we investigate whether the Media Fragments URI addressing scheme together with a natural language generation framework realized through a text-to-speech system provides a feasible and practicable way to visually and audially describe the differences between media items of type photo and/or video, so that human-friendly debugging of the deduplication algorithm is made possible. A short screencast illustrating the approach is available online at http://youtu.be/DWqwEnhqTSc.
