Alberto Del Bimbo, MICC Director, was one of the invited keynote speaker. His keynote was about “Social Media Annotation”.

Abstract: the large success of online social platforms for creation, sharing and tagging of user-generated media has lead to a strong interest by the multimedia and computer vision communities in research on methods and techniques for annotating and searching social media. Visual content similarity, geo-tags and tag co-occurrence, together with social connections and comments, can be exploited to perform tag suggestion as well as to perform content classification and clustering and enable more effective semantic indexing and retrieval of visual data. However there is need to countervail the relatively low quality of these metadata user produced tags and annotations are known to be ambiguous, imprecise and/or incomplete, overly personalized and limited – and at the same time take into account the ‘web-scale’ quantity of media and the fact that social network users continuously add new images and create new terms. We will review the state of the art approaches to automatic annotation and tag refinement for social images and discuss extensions to tag suggestion and localization in web video sequences.
