Call for Participation The 2nd Workshop on Interactive Visual Text Analytics: Task-Driven Analysis of Social Media Content a workshop at IEEE VisWeek '12 October 14, 2012 http://research.microsoft.com/en-us/um/people/shliu/tasmc WORKSHOP GOAL Hundreds of millions of people express themselves daily on social media, such as Twitter. They share their personal status updates such as "just got married", publicize location-based information such as where they were and are planning to go, and voice their sentiment about products and services. Since the buzz of the crowd on social media provides a great deal of information that was not available before, businesses and organizations have started leveraging social media to profile customers, derive brand perception, gauge citizen sentiments, and predict the stock market. For example, retailers track and examine customer social media posts to understand customer sentiments toward their products and services. Healthcare providers analyze patient posts in online forums to better understand patients' needs and progresses. The goal of this workshop is to bring together researchers and practitioners interested in social media, text visualization, text analytics, and visual analytics, to define the emerging field of visual text analysis of social media. We are particularly interested in discussing tasks, techniques, and applications in different domains. In other words, we would like to establish a better understanding what major tasks that people aim to accomplish in using visual text analysis of social media and how different tasks call for different text analytics and/or interactive visualization techniques. As a result, we hope to derive a task taxonomy that describes the intended user tasks, and corresponding text analytics and visualization technologies in the context of analyzing social media text. This taxonomy can then be used to guide the use and development of text analytics and visualization techniques. PAPER SUBMISSION We invite 2-4 page position paper submissions that address topics related to visual text analysis of social media, with a requirement that every submission must clearly state the specific tasks to be achieved. Topics of interest include but are not limited to: - Task taxonomy of analysis of social media text - Visual metaphors for social media text - Perception and cognition in visualizing social media text - Systems, languages, and architectures for social media text analysis - Collaborative analysis of social media text - Real-time visualization of streaming social media text - Visual opinion summarization from social media - Visual event identification and prediction from social media - Visual representations and techniques for dealing with uncertainty in interactive social media text analysis - Industry-specific applications of visual analysis of social media (e.g. Retail, Healthcare, Government, etc.) - Studies and evaluation of social media text visualization techniques, systems, metrics, and bench-marks - Datasets and tasks for visual text analysis of social media IMPORTANT DATES August 31st: Position paper due September 14th: Notification October 1st: Final version of papers due October 14th: Visual text analytics workshop Submission instructions will be available on the workshop website ORGANIZERS Eser Kandogan, IBM Research-Almaden Shixia Liu, Microsoft Research Asia John Stasko, Georgia Tech Huahai Yang, IBM Research-Almaden Michelle Zhou, IBM Research-Almaden
