  Our work aims to generate visualizations to enable meta-analysis of analytic
provenance and aid better understanding of analysts' strategies during
exploratory text analysis. We introduce ProvThreads, a visual analytics
approach that incorporates interactive topic modeling outcomes to illustrate
relationships between user interactions and the data topics under
investigation. ProvThreads uses a series of continuous analysis paths called
topic threads to demonstrate both topic coverage and the progression of an
investigation over time. As an analyst interacts with different pieces of data
during the analysis, interactions are logged and used to track user interests
in topics over time. A line chart shows different amounts of interest in
multiple topics over the duration of the analysis. We discuss how different
configurations of ProvThreads can be used to reveal changes in focus throughout
an analysis.
