On the Cooperative Creation of Multimedia Meaning

In this paper, we propose a content-based method the for semiautomatic organization of photo albums based on the analysis of how different users organize their own pictures. The goal is to help the user in dividing his pictures into groups characterized by a similar semantic content. The method is semi-automatic: the user starts to assign labels to the pictures and unlabeled pictures are tagged with proposed labels. The user can accept the recommendation or make a correction. The method is conceptually articulated in two parts. First, we use a suitable feature representation of the images to model the different classes that the users have collected, second, we look for correspondences between the criteria used by the different users. A quantitative evaluation of the proposed approach is proposed based on pictures of a set of members of the flickr (R) photo-sharing community.
