BLACKSBURG, Va., March 21, 2005 –   Virginia Bioinformatics Institute Research Assistant Professor Karen Duca, Purvi Saraiya, graduate research assistant at VBI, and Virginia Tech Computer Science Assistant Professor Chris North presented a paper at the IEEE Symposium on Information Visualization (InfoVis 2004) on October 10-12, 2004.

In the paper, entitled "An Evaluation of Microarray Visualization Tools for Biological Insight," Duca, Saraiya, and North identify several distinct characteristics of insight that enable biologists to recognize and quantify it by evaluating five popular microarray visualization tools. A wide variety of visualization tools have been created to facilitate data analysis, oftentimes creating a dilemma for biologists in choosing the best tool for their situation. The tool that works best for one biologist may not work well for another due to differences in the type of insight they seek from their data.

A primary purpose of a visualization tool is to provide domain-relevant insight into the data. Ideally, any user wants maximum information in the least possible time. The conclusions presented in the evaluation can guide biologists in selecting the best tool for their data, and computer scientists in developing and evaluating visualizations.

InfoVis is the primary meeting in the field of information visualization, and was held in conjunction with the IEEE Visualization 2004 conference in Austin, Texas. IEEE, which stands for the Institute of Electrical and Electronics Engineers, is an association dedicated to the advancement of technology. The organization brings together scientists of all disciplines, including engineering, electrical and computer science, and biology, and has over 361,000 members in more than 150 countries.
