Viégas DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.165 Abstract We present a new technique, the phrase net, for generating visual overviews of unstructured text. A phrase net displays a graph whose nodes are words and whose edges indicate that two words are linked by a user-specified relation. These relations may be defined ... http://vgtc.org/wpmu/infovis09/2009/10/27/best-paper-award-mapping-text-with-phrase-nets/ Authors Yanhua Chen Lijun Wang Ming Dong Jing Hua DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.140 [flv width="400" height="300"]http://media.computer.org/sponsored/conf/vis/2009/info_s08p04.flv[/flv] Download - Video | Audio Running Time: 18 min 28 sec Abstract With the rapid growth of the World Wide Web and electronic information services, text corpus is becoming available on-line at an incredible rate. By displaying text data in a logical ... http://vgtc.org/wpmu/infovis09/2009/10/27/exemplar-based-visualization-of-large-document-corpus/ Authors Jian Zhang Chaomei Chen Jiexun Li DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.202 Abstract Visualizing the intellectual structure of scientific domains using co-cited units such as references or authors has become a routine for domain analysis. In previous studies, paper-reference matrices are usually transformed into reference-reference matrices to obtain co-citation relationships, which are then visualized in different representations, typically ... http://vgtc.org/wpmu/infovis09/2009/10/27/visualizing-the-intellectual-structure-with-paper-reference-matrices/ Authors Hendrik Strobelt Daniela Oelke Christian Rohrdantz Andreas Stoffel Daniel A. Keim Oliver Deussen DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.139 Abstract Finding suitable, less space consuming views for a document’s main content is crucial to provide convenient access to large document collections on display devices of different size. We present a novel compact visualization which represents the document’s key semantic as a ... http://vgtc.org/wpmu/infovis09/2009/10/27/document-cards-a-top-trumps-visualization-for-documents/ Authors Fernanda B. Viégas Martin Wattenberg Jonathan Feinberg DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.171 Abstract We discuss the design and usage of “Wordle,” a web-based tool for visualizing text. Wordle creates tag-cloud-like displays that give careful attention to typography, color, and composition. We describe the algorithms used to balance various aesthetic criteria and create the distinctive Wordle layouts. We ... http://vgtc.org/wpmu/infovis09/2009/10/27/participatory-visualization-with-wordle/ Authors Chris Muelder Francois Gygi Kwan-Liu Ma DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.196 Abstract In serial computation, program pro?ling is often helpful for optimization of key sections of code. When moving to parallel computation, not only does the code execution need to be considered but also communication between the different processes which can induce delays that are detrimental to ... http://vgtc.org/wpmu/infovis09/2009/10/27/visual-analysis-of-inter-process-communication-for-large-scale-parallel-computing/ Authors Michael Bostock Jeffrey Heer DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.174 Abstract Despite myriad tools for visualizing data, there remains a gap between the notational efficiency of high-level visualization systems and the expressiveness and accessibility of low-level graphical systems. Powerful visualization systems may be inflexible or impose abstractions foreign to visual thinking, while graphical systems such as rendering ... http://vgtc.org/wpmu/infovis09/2009/10/27/protovis-a-graphical-toolkit-for-visualization/ Authors Harald Piringer Christian Tominski Philipp Muigg Wolfgang Berger DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.110 Abstract During continuous user interaction, it is hard to provide rich visual feedback at interactive rates for datasets containing millions of entries. The contribution of this paper is a generic architecture that ensures responsiveness of the application even when dealing with large data and that ... http://vgtc.org/wpmu/infovis09/2009/10/27/a-multi-threading-architecture-to-support-interactive-visual-exploration/ Authors Bryan McDonnel Niklas Elmqvist DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.191 Abstract Modern programmable GPUs represent a vast potential in terms of performance and visual flexibility for information visualization research, but surprisingly few applications even begin to utilize this potential. In this paper, we conjecture that this may be due to the mismatch between the high-level abstract data ... http://vgtc.org/wpmu/infovis09/2009/10/27/towards-utilizing-gpus-in-information-visualization-a-model-and-implementation-of-image-space-operations/ Authors Michael Ogawa Kwan-Liu Ma DOI Bookmark: http://doi.ieeecomputersociety.org/10.1109/TVCG.2009.123 [flv width="400" height="300"]http://media.computer.org/sponsored/conf/vis/2009/info_s07p01.flv[/flv] Download - Video | Audio Running Time: 17 min 58 sec Abstract In May of 2008, we published online a series of software visualization videos using a method called code_swarm. Shortly thereafter, we made the code open source and its popularity took off. This ... http://vgtc.org/wpmu/infovis09/2009/10/27/code-swarm-a-design-study-in-organic-software-visualization/
