Before revision:  To address this shortcoming, we present ConceptScope, a text visualization technique that aids visual analysis of documents by referencing a domain ontology to represent the conceptual relationships in a document . ConceptScope uses a Bubble TreeMap visualizationlinked to multiple coordinated views of document structure and concept hierarchy . The visualization also includes overviews of each concept and corresponding information from the document . ConceptScope provides two visualization modes: an exploration mode that allows an overview+detail examination of a given document, and a comparison mode that allows the user to visually compare conceptual structure between multiple documents .

ConceptScope uses a Bubble TreeMap visualizationlinked to multiple coordinated views of document structure and concept hierarchy with text overviews further aid document analysis. ConceptScope facilitates exploration and comparison of single and multiple documents respectively . ConceptScope provides two visualization modes: an exploration mode that allows an overview+detail examination of a given document, and a comparison mode that allows the user to visually compare conceptual structure between multiple documents .
