Overview
The collection and analysis of event sequence data occurs in many domains. For instance, e-commerce companies seek to understand customer behaviors from clickstream data and inform marketing decisions. User logs generated from desktop applications can be helpful to understand user intent and tasks for building intelligent assistants. In the healthcare domain, electronic health records are sources of information that can provide insights into whether recommended guidelines are followed. The sheer volume and complexity of event sequences present many challenges in the visual analysis of such data.
We employ and integrate methods such as data mining, visualization and predictive analytics to support visual analysis of event sequence data.
If you have event sequence data to analyze/visualize and think we may be of any help, we’d love to hear from you! Feel free to send an email to Prof. Liu (leozcliu at umd.edu).
