Agile Browsing of a Document Collection with Dynamic Taxonomies

International audienceDynamic 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
