Call For Papers

As visualization researchers, our ongoing challenge is often to leverage the voluminous data that is being captured to drive decision making and insights. Common to such data are temporal events, data points with both a timestamp and event type, so understanding patterns of temporal event sequences is an important problem to many domains.

For example, medical researchers may wish to leverage the data captured by electronic health records to determine if certain sequences of medical events correlate with positive outcomes. Similarly, city government officials may wish to leverage the temporal data collected from their transportation systems, call centers, and law enforcement agencies to improve their cities’ services. Engineers might analyze temporal events from system logs to manage large-scale distributed system performance. Consumer services analysts might seek to understand social media and shopping patterns.

Recently, there has been an increasing amount of visualization research focusing on temporal events. Papers on this topic have appeared at IEEE VIS, other visualization conferences, and at many domain-specific venues.

The main question behind the proposed workshop is: How can we unify and advance the role of visualization in temporal event analysis? The workshop will gather visualization researchers together to discuss the interesting opportunities and challenges visualization may face with temporal events. It aims to both gather the existing literature on the subject and build a research agenda for future research.

In order to encourage collaboration and comparison, we will distribute 1-2 sample datasets before the workshop. We will encourage, but not require, presenters of papers and demos to show how their system performs on these sample datasets; this will better allow us all to discuss the tradeoffs of different designs.


Topics and Scope

This workshop aims to increase awareness about this interesting opportunity for visualization research, collect and compare examples of existing and ongoing research in this area, and to create a preliminary temporal event analytics research agenda for visualization researchers. The workshop will allow participants to showcase their existing research and ideas, and to learn and reflect on the latest advances in visualization of temporal events. Therefore, work which addresses any of the following questions would be highly relevant:

  • How can visualization help data scientists make sense of temporal events?
  • How can end users be sure the visualizations are made of temporal-relevant features?
  • How can visual analytics help researchers include their domain knowledge into the temporal event analysis process?
  • How do we build benchmark datasets and ground truth to objectively compare different temporal event visualizations?
  • What are good and suitable processes to ensure usefulness of event visualizations?
  • How can we use visual analytics to “explain” patterns derived from frequent sequence data mining algorithms?
  • How can visualization help sequence visualizers gain trust into their results?
  • How can we compare and evaluate extant methods for temporal event analysis?
  • What techniques are good for what situations (many different event types vs. few event types; many users vs. few users; long streams vs. short streams?)
  • Can we gather some sample datasets to help compare and contrast existing techniques>
Research topics include, but are not limited to, the following:
  • Visualization techniques for temporal event analysis,
  • Real and synthetic data sets and benchmarks,
  • Taxonomies of temporal event analysis tasks,
  • Case studies, user Challenges, and user Stories of temporal event visualizations.
  • Theory and algorithms for event analysis (e.g., data structures, models, taxonomies, etc.)

How to Submit

We solicit a wide range of submissions which fall within the scope outlined above. Authors are invited to submit to any of three tracks:
  • Research papers (3-4 pages) should present new work or a novel synthesis of already published research contributions. Articles describing emerging research or works-in-progress are welcome. Submissions will be peer-reviewed by the organizers and accepted manuscripts will be made available on the workshop website. Authors of accepted papers will have the opportunity to orally present their work during the workshop.
  • Position papers (1-2 pages) are short statements describing ideas to discuss during the workshop. They will be peer-reviewed by the organizers, and accepted papers will be made available on the workshop website.
  • Poster or Interactive Demonstration abstracts (1-2 pages). Submissions will be peer-reviewed by the organizers, and accepted abstracts will be made available on the workshop website. Authors of accepted papers will have the opportunity to showcase their work during a poster/demo session at the workshop.
Submissions are open and due by August 22, 2016. Papers should be formatted using the TVCG Formatting Guidelines and submitted as a PDF.
