Demonstration of Logan: Event Sequence Exploration

Date

August 26, 2016

Overview

Logan is a visualization tool for visually building queries against sequences of events, phrased as visual regular expressions. The tool finds all sequences of events that match the expression. It features an ability to visually construct queries; to use the results of the queries to create new interactions; and to compare cohorts of sequences. In the video, we show an exploration against the logs of a (simulated) e-commerce store. We first examine what actions users take before and after they check out; we then look at the factors that drive users adding items to their shopping carts.
