Therefore, the analysis of patent information has become an inevitable task for a variety of interest groups. The retrieval of relevant patent information is an integral part of almost every patent analysis scenario. ... http://vgtc.org/wpmu/vast09/2009/10/14/iterative-integration-of-visual-insights-during-patent-search-and-analysis/ Authors Stephen Rudolph Anya Savikhin David S. Ebert Download - Slides Abstract FinVis is a visual analytics tool that allows the non-expert casual user to interpret the return, risk and correlation aspects of financial data and make personal finance decisions. This interactive exploratory tool helps the casual decision-maker quickly choose between various financial portfolio options ... http://vgtc.org/wpmu/vast09/2009/10/14/finvis-applied-visual-analytics-for-personal-financial-planning/ Authors Daniela Oelke Ming Hao Christian Rohrdantz Daniel A. Keim Umeshwar Dayal Lars-Erik Haug Halldór Janetzko Abstract Today, online stores collect a lot of customer feedback in the form of surveys, reviews, and comments. This feedback is categorized and in some cases responded to, but in general it is underutilized – even though customer satisfaction is essential to the ... http://vgtc.org/wpmu/vast09/2009/10/14/visual-opinion-analysis-of-customer-feedback-data/ Authors Janko Dietzsch Julian Heinrich Kay Nieselt Dirk Bartz Download - Slides Abstract We present a new application, SpRay, designed for the visual exploration of gene expression data. It is based on an extension and adaption of parallel coordinates to support the visual exploration of large and high-dimensional datasets. In particular, we investigate the visual analysis ... http://vgtc.org/wpmu/vast09/2009/10/14/spray-a-visual-analytics-approach-for-gene-expression-data/ Authors Boonthanome Nouanesengsy Sang-Cheol Seok Han-Wei Shen Veronica J Vieland Download - Audio | Slides Running Time: 17 min 41 sec Abstract Gene mapping is a statistical method used to localize human disease genes to particular regions of the human genome. When performing such analysis, a genetic likelihood space is generated and sampled, which results ... http://vgtc.org/wpmu/vast09/2009/10/14/using-projection-and-2d-plots-to-visually-reveal-genetic-mechanisms-of-complex-human-disorders/ Authors Robert Kincaid Kurt Dejgaard Download - Audio | Slides Running Time: 21 min 40 sec Abstract Protein complexes are formed when two or more proteins noncovalently interact to form a larger three dimensional structure with specific biological function. Understanding the composition of such complexes is vital to understanding cell biology at the ... http://vgtc.org/wpmu/vast09/2009/10/14/massvis-visual-analysis-of-protein-complexes-using-mass-spectrometry/ Authors Tatiana von Landesberger Melanie Görner Tobias Schreck Download - Slides Abstract In this paper, we present a system for the interactive visualization and exploration of graphs with many weakly connected components. The visualization of large graphs has recently received much research attention. However, specific systems for visual analysis of graph data sets consisting of ... http://vgtc.org/wpmu/vast09/2009/10/13/visual-analysis-of-graphs-with-multiple-connected-components/ Authors Pak Chung Wong Patrick Mackey Kristin A. Cook Randall M. Rohrer Harlan Foote Mark A. Whiting Abstract This paper presents a working graph analytics model that embraces the strengths of the traditional top-down and bottom-up approaches with a resilient crossover concept to exploit the vast middle-ground information overlooked by the two extreme analytical approaches. Our graph analytics ... http://vgtc.org/wpmu/vast09/2009/10/13/a-multi-level-middle-out-cross-zooming-approach-for-large-graph-analytics/ Authors Youn-ah Kang Carsten Görg John Stasko Abstract Despite the growing number of systems providing visual analytic support for investigative analysis, few empirical studies of the potential benefits of such systems have been conducted, particularly controlled, comparative evaluations. Determining how such systems foster insight and sensemaking is important for their continued growth and study, however. ... http://vgtc.org/wpmu/vast09/2009/10/13/evaluating-visual-analytics-systems-for-investigative-analysis-deriving-design-principles-from-a-case-study/
