Concept: The Galaxies visualization uses the image of stars in the night sky to represent a set of documents. Each document is represented by a single "docustar." Closely related documents cluster together while unrelated documents are separated by large distances. Several analytical tools are provided with Galaxies to allow users to investigate the document groupings, query the document contents, and investigate time-based trends.

Status: The Galaxies visualization is deployed as part of the SPIRE information visualization tool suite.
Additional information about the SPIRE tool suite is available in The Gallery.

Concept: In the ThemeView^TM visualization, the topics or themes within a set of documents are shown as a relief map of natural terrain. The mountains in the ThemeView^TM indicate dominant themes. The height of the peaks indicates the relative strengths of the topics in the document set. Similar themes appear close together, while unrelated themes are separated by larger distances. ThemeView^TM provides a visual overview of the major topics contained in a set of documents. Combined with its exploration tools, ThemeView^TM permits the analyst to identify unanticipated relationships and examine changes in topics over time.

* Note: "ThemeView^TM " was formerly known as Themescape.

Status: The ThemeView^TM visualization is deployed as part of the SPIRE information visualization tool suite.
