A method of accessing information includes processing a query, searching a collection of data for a set of results matching the query, selectively reducing the set of results to generate a subset of results, outputting a prose rendition of the query and outputting the subset of results. The stent is compressible and self-expandable substantially to a pre-compressed configuration. Furthermore, an operator can arbitrarily set and modify the range to which weight is applied, the range for displaying the gradation color scale, and the range to be combined.
