The first web-based tool that can be used to explore the enriched collections is a metadata filtering & clustering service. Several metadata types and values can be defined as filter. The figure below, for example, shows the result of querying the collection for images that (a) contain a horse and a church, or (b) a tank and a man. These and other types of queries can be evaluated at the UGESCO website. Furthermore, we are also investigating a methodology to cluster the pictures based on their semantic similarity. In this context, the Object Relation Network and bag of semantics seems interesting mechanisms. However, other approaches will also be evaluated.
