Summary --> SparkClouds: Visualizing Trends in Tag Clouds

Introduction

These days tag clouds are found all over the internet. Although they display the relative tag frequency, popularity, or importance by font size very well you will have difficulties to figure out how tag clouds evolved over time. That’s what Bongshin Lee et al. paper is all about. It introduces SparkClouds as a new breed of tag clouds, combining sparklines and typically tag cloud features to visualize changes across multiple tag clouds over time. SparkClouds will further be compared to three other types of visualization in terms of speed and accuracy to find out if SparkClouds’ ability to show trends is preferred.
