Visualizing a Thinker's Life.

This paper presents a visualization framework that aids readers in understanding and analyzing the contents of medium-sized text collections that are typical for the opus of a single or few authors. We contribute several document-based visualization techniques to facilitate the exploration of the work of the German author Bazon Brock by depicting various aspects of its texts, such as the TextGenetics that shows the structure of the collection along with its chronology. The ConceptCircuit augments the TextGenetics with entities - persons and locations that were crucial to his work.

WORDGRAPH: Keyword-in-Context Visualization for NETSPEAK's Wildcard Search.
