Current text visualization techniques typically provide overviews of document content and structure using intrinsic properties such as term frequencies, term co-occurrences, and sentence structures. However, these visualization techniques do not provide conceptual overviews that consider domain-relevant knowledge that is needed when examining documents such as research articles , technical panels, or news reports. 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 . We demonstrate ConceptScope by visualizing research articles and transcripts of technical presentations in the computer sciencedomain, and compare it with Docuburst, the popular knowledge visualization toolfor text .

To address this shortcoming, we present ConceptScope, a technique that utilizes a domain ontology to represent the conceptual relationships in a document in the form of a Bubble Treemap visualization. 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 . We demonstrate ConceptScope by visualizing research articles and transcripts of technical presentations in computer science. In a comparative study with DocuBurst, a popular document visualization tool, ConceptScope was found to be more informative in exploring and comparing domain-specific documents, but less so when it came to documents that spanned multiple disciplines .
