Agile Browsing of a Document Collection with Dynamic Taxonomies

Dynamic taxonomies and faceted search are increasingly used to organize and browse document collections. The main function of  dynamic taxonomies is to start with the full collection, and zoom-in  to a small enough subset of items for direct inspection. In this  paper, we present other navigation modes than zoom-in for less directed and more exploratory browsing of a document collection. The  presented navigation modes are zoom-out, shift, pivot, and querying  by examples. These modes correspond to query transformations, and  make use of boolean operators. Therefore, the current focus is  always clearly specified by a query.
