WORKSHOP: Temporal Event Sequence Analysis EventFlow and CoCo User Group Meeting 2016

WORKSHOP: Temporal Event Sequence Analysis
EventFlow and CoCo User Group Meeting

Thursday, May 26, 2016

A workshop of the
33rd Human-Computer Interaction Lab Symposium
University of Maryland

Overview and Topics

The growing volume of temporal data available from sensors, social media sources, Web logs, and medical histories present remarkable opportunities for researchers and policy analysts. Research at HCIL has led to the development of a family of tools for the exploration of temporal event sequences, such as EventFlow to summarize and search event sequence patterns and CoCo – short for Cohort Comparison — for the comparison of groups of records and their event sequences.

This workshop will allow researchers who are using those tools to share their findings and strategies for successful event data analysis. We anticipate various application domains to be discussed, including the analysis of Electronic Health Record data, activity log analysis, learning analytics, and more. We also welcome discussions of other uses of visual approaches, statistical methods, machine learning, etc. to study temporal patterns in event sequences, where the goals may be to find common patterns, rare events, similar records etc. Topics might also include data cleaning, integration from multiple sources, coping with incomplete or conflicting information, and presentation of result sets.

This workshop will include talks (followed by ample time for discussions) from:

  • HCIL researchers (e.g. our latest work on EventFlow and our newer work on cohort comparison)
  • Users of HCIL tools such as EventFlow (who will be invited to report on their case studies), and
  • Other researchers working on similar topics will be selected to present their work (please contact us if you are interested).

To Present Your Work: 

  • If you are interested in presenting please submit a short abstract (~ 300 words max). Summarize what you would like to present on the topic of Exploring Temporal Patterns in Electronic Health Record Data, and provide pointers to papers and screen shots as needed.
  • Submit to Catherine Plaisant at (Deadline: May 1, 2016, Notification: May 8, 2016). If we receive too many requests, we may ask you to bring a poster for presentation during the breaks.

To Participate:

Come and join us! The workshop is opened to all. Space permitting, so plan to register early (mid-May at the latest is best).


Questions: Please contact Catherine Plaisant (
