ThemeView

A ThemeView map of the dataset shows the major themes and their associations as a color encoded terrain. Each hexagonal cell corresponds to a key term. Highly associated terms neighbor each other in the terrain. The height at the center of a cell reflects the number of documents containing that cell’s corresponding term. The height between adjacent cells reflects the number of documents containing both of those cells corresponding terms. Dark lines between cells appear where adjacent terms do not occur within any of the same documents. Major themes appear in the ThemeView terrain as sets of adjacent term cells. By default, the top term for each theme in the terrain is labeled.

Opening the ThemeView

On the IN-SPIRE main toolbar, click ThemeView , or choose Tools > ThemeView.

Selecting a set of documents will result in those documents’ ten most related terms being listed. Clicking a related term will select the documents in which it occurs.
