When an item is published to a Semantic Bank, tags assigned to it are carried along. As a conse- quence, the bank’s members pool together not only the information items they have collected but also their organization schemes applied on those items. The technique of pooling together keywords has recently gained popularity through services such as [6], Flickr [25], and CiteULike [4] as a means for a community to collab- oratively build over time a taxonomy for the data they share. This strategy avoids the upfront cost for agreeing upon a taxonomy when, perhaps, the nature of the information to be collected.
