Abstract
We present a text document search engine with several new visualization front-ends that aid navigation through the set of documents returned by a query (hit documents). Our methods are based on identifying and selecting keywords on the fly. The choice of keywords depends not only on the frequency of their occurrence within hit documents but also on the specificity of their occurrence just within these hit documents. Keywords are subsequently used to obtain a sparse document representation and to compute document clusters using a variant of the buckshot algorithm. One of the visualization front-ends uses the sparse document representation to obtain keyword clusters. We make use of the clustering to group the documents returned from the search visually, and to label the groups with their most salient keywords. The different front-ends cater for different user needs. Two of them can be employed to browse cluster information as well as to drill down or up in clusters and refine the search...
