Topic models have been shown to reveal the semantic content in large corpora. Many individualized visualizations of topic models have been reported in the lit-erature, showing the potential of topic models to give valuable insight into a cor-pus. However, good, general tools for browsing the entire output of a topic model along with the analyzed corpus have been lacking. We present an interactive tool that incorporates both prior work in displaying topic models as well as some novel ideas that greatly enhance the visualization of these models.
