Leonidas Deligiannidis, Krys J. Kochut, Amit P. Sheth
2007 Proceedings of the ACM first workshop on CyberInfrastructure: information management in eScience - CIMS '07  
In response to the user-controlled, semantics-driven direction of the exploration, the PGV explorer obtains the necessary sub-graphs from the RDF pager and enables their incremental visualization leaving  ...  We present Paged Graph Visualization (PGV), a new semiautonomous tool for RDF data exploration and visualization.  ...  Any opinions, findings, and conclusions or recomations expressed in this material are those of the authors and t necessarily reflect  ...

Text mapping: Visualising unstructured, structured, and time-based text collections

Vedran Sabol, Keith Andrews, Wolfgang Kienreich, Michael Granitzer, Joachim Hasebrook
2008 International Journal of Intelligent Decision Technologies  
Large collections of text documents are increasingly common, both in business and personal information environments.  ...  Flat text collections are often visualised using distance calculations between documents and subsequent (distance-preserving) projection.  ...  , the Austrian Ministry of Economics and Labor and by the State of Styria.  ...

FacetScape: A Visualization for Exploring the Search Space

Christin Seifert, Johannes Jurgovsky, Michael Granitzer
2014 2014 18th International Conference on Information Visualisation  
This visualization combines Voronoi subdivision and a tag cloud representation of the search facets.  ...  Search result visualizations, especially for faceted browsing, aim at supporting users to find their way through large document collections.  ...  In Tasks 1 and 4 users needed to exploit the search space, whereas Task 2 and 5 required more explorative search behavior.  ...

STREAMIT: Dynamic visualization and interactive exploration of text streams

Jamal Alsakran, Yang Chen, Ye Zhao, Jing Yang, Dongning Luo
2011 2011 IEEE Pacific Visualization Symposium  
Text streams demand an effective, interactive, and on-the-fly method to explore the dynamic and massive data sets, and meanwhile extract valuable information for visual analysis.  ...  In this paper, we propose such an interactive visualization system that enables users to explore streaming-in text documents without prior knowledge of the data.  ...  We thank the anonymous reviewers for helpful reviews to improve the paper.  ...

Organizing Search Results with a Reference Map

Arlind Nocaj, Ulrik Brandes
2012 IEEE Transactions on Visualization and Computer Graphics  
a) reference map (entire database) (b) query hits by relevance and similarity Fig. 1. Maintaining the global organization of subsets in hierarchically clustered document collections.  ...  Here, the reference map is built from an MDS layout of the items in a Voronoi treemap representing their hierarchical clustering, and we use techniques from dynamic graph layout to align query results  ...  We thank Daniel Keim and Florian Mansmann for providing us with the example data.  ...

Evaluating a System for Interactive Exploration of Large, Hierarchically Structured Document Repositories

M. Granitzer, W. Kienreich, V. Sabol, K. Andrews, W. Klieber
IEEE Symposium on Information Visualization  
The InfoSky visual explorer is a system enabling users to interactively explore large, hierarchically structured document collections.  ...  Usability testing of an early prototype implementation of InfoSky revealed several design issues which prevented users from fully exploiting the power of the visual metaphor.  ...  We would like to thank our colleagues at the Know-Center, Hyperwave, and Graz University of Technology for their feedback and suggestions.  ...

Assessing Visualization Techniques for the Search Process in Digital Libraries [article]

Wilko van Hoek, Philipp Mayr
2013 arXiv   pre-print
The search process typically can be separated into three major phases: query formulation and refinement, browsing through result lists and viewing and interacting with documents and their properties.  ...  We conclude that this is most likely due to the fact that most systems are not evaluated intensely in real-life scenarios with real information seekers and that results of the interesting visualization  ...  The System InfoSky (Keith Andrews et al., 2002) introduced in 2002 combined document relatedness and hierarchical structures (e.g. collection structure, classification information).  ...

Visual Analysis and Knowledge Discovery for Text [chapter]

Christin Seifert, Vedran Sabol, Wolfgang Kienreich, Elisabeth Lex, Michael Granitzer
2013 Large-Scale Data Analytics  
Providing means for effectively accessing and exploring large textual data sets is a problem attracting the attention of text mining and information visualization experts alike.  ...  Besides introducing human knowledge and visual pattern recognition into the analytical process, it provides the possibility to improve the performance of automatic methods through user feedback.  ...  Exploiting integrated metadata and structure between documents becomes essential in order to improve summarization and keyword extraction, as shown in [29] .  ...
