DecisionFlow: Visual Analytics for High-Dimensional Temporal Event Sequence Data

Abstract: Temporal event sequence data is increasingly commonplace, with applications ranging from electronic medical records to financial transactions to social media activity. Previously developed techniques have focused on low-dimensional datasets (e.g., with less than 20 distinct event types). Real-world datasets are often far more complex. This paper describes DecisionFlow, a visual analysis technique designed to support the analysis of high-dimensional temporal event sequence data (e.g., thousands of event types).… Show more

“…They extract and highlight the common event sequences from patient records. Outflow (Wongsuphasawat and Gotz 2012) and DecisionFlow (Gotz and Stavropoulos 2014) use Sankey diagram (Riehmann et al 2005) style visualisation to help visualise and analyse the causal relationships of events in complex event sequences.…”
