PaperLens is a novel visualization that reveals trends, connections, and activity throughout a conference community. It tightly couples views across papers, authors, and references. PaperLens was developed to visualize 8 years (1995-2002) of InfoVis conference proceedings and was then extended to visualize 23 years (1982-2004) of the ACM SIGCHI conference proceedings. This paper describes how we designed PaperLens and analyzed the data from these two conferences, including some observations of patterns and relationships discovered using PaperLens. We also discuss the difficulties of handling incomplete, error-prone data. We then describe a user study we conducted to focus our redesign efforts along with the design changes we made to address usability issues. In addition, we summarize lessons learned in the process of design and scaling up to the larger set of CHI conference papers. The visualization contributes to the field by allowing users to discover research trends, patterns and relationships not possible with existing tools.
