Zusammenfassung
In this paper, we present a novel relational visualization that
supports people at information discovery tasks in digital libraries. This
visualization displays search query results structured into topics and
highlights the intersections between them. The proposed visual repre-
sentation introduces interactive drag-and-drop operations for manipulation of the generated topics. These operations mirror the human online
searching strategies that involve boolean AND, OR, and NOT operators.
In doing so, the information seeker can refine (or relax) a search query
in an interactive way during a focusing or a defocusing phase. The intersections of topics are made explicitly visible to enable the information
seeker to avoid frustrating "no hits" situations.
