Exploring and Summarizing Document Colletions with Multiple Coordinated Views

Knowledge work such as summarizing related research in preparation for writing, typically requires the extraction of useful information from scientific literature. Nowadays the primary source of information for researchers comes from electronic documents available on theWeb, accessible through general and academic search engines such as Google Scholar or IEEE Xplore. Yet, the vast amount of resources makes retrieving only the most relevant results a difficult task. As a consequence, researchers are often confronted with loads of low-quality or irrelevant content. To address this issue we introduce a novel system, which combines a rich, interactive Web-based user interface and different visualization approaches. This system enables researchers to identify key phrases matching current information needs and spot potentially relevant literature within hierarchical document collections. The chosen context was the collection and summarization of related work in preparation for scientific writing, thus the system supports features such as bibliography and citation management, document metadata extraction and a text editor. This paper introduces the design rationale and components of the PaperViz. Moreover, we report the insights gathered in a formative design study addressing usability.
