What Fresh Media Are You Looking For? Extracting Media Items from Multiple Social Networks

by Giuseppe Rizzo, Thomas Steiner, Raphaël Troncy, Ruben Verborgh, José Luis Redondo Garcia, and Rik Van de Walle

Social networks play an increasingly important role to provide fresh media items related to daily life moments or live coverage of events. One of the problems is that media are spread over multiple social networks. In this paper, we propose a social-network-agnostic approach for collecting recent images and videos which can be potentially attached to an event. The media can be later on processed for the automatic generation of visual summaries in the form of media galleries. Our approach includes the alignment of the varying search result formats that these social networks return while putting the media items in correspondence with the status updates and stories they are related to. More precisely we leverage on: (i) visual features from media items, (ii) Textual features from status updates, and (iii) social features from social networks to interpret, deduplicate, cluster, and visualize media items. We address the technical details of media item extraction and media item processing, discuss criteria for media item filtering and envision several visualization options for media presentation. We have developed a user interface publicly available at http://eventmedia.eurecom.fr/media-finder, which implements the framework detailed in this paper. The evaluation is divided in two parts: first we assessed the performances of the image process deduplication and then we propose a human evaluation of the summary creation compared with Teleportd and Twitter media galleries.
