Researchers want to…
1. Find a specific paper2. Explore a research area3. Do retrospective analysis4. Share their results
3
1. Find a specific paper
• Metadata or PDF?• From memory (search)• From reference list– DOI/URL– Search
4
2. Exploring a research area
• Foundations• Emerging research topics• State of the art/open problems• Collaborations & relationships between
Communities• Field evolution• Easily understandable surveys
5
User requirements
• Control over the paper collection– Choose custom subset via query, then iteratively drill down,
filter, & refine• Overview either as visualization or text statistics– Orient within subset
• Easy to understand metrics for identifying interesting papers– Ranking & filtering
• Create groups & annotate with findings– Organize discovery process– Share results
6
Action Science Explorer
• Bibliometric lexical link mining to create a citation network and citation context
• Network clustering and multi-document summarization to extract key points
• Potent network analysis and visualization tools

10
Statistics & visualization
• Network statistics– Degree– Betweenness– Closeness– Pagerank
• Attributes– Year– Downloads– Citations– References
12
Citation context & summarization
• Citation context– Key contributions– Critical reception– Citations to subsequent/similar work
• Hyperlinked citations in text– See surrounding context of citation– View cited papers while reading
• Multi-document summarization– Citation context– Abstract– Full text
13
3. Retrospective analysis
• Automatic collection & processing of bibliometric data
• Easy access to visual analytic tools for finding clusters, trends, outliers
• Communities for sharing data, tools, & results
14
STICK Project
• Scientific, data-driven way to track innovations– Vs. current expert-based, time consuming
approaches (e.g., Gartner’s Hype Cycle, tire track diagrams)
• Includes both concept and product forms– Study relationships between
• Study the innovation ecosystem– Organizations & people– Both those producing & using innovations

Case study: tree visualization
• Problem: Traditional 2D node-link diagrams of trees become too large
• Solutions:– Treemaps: Nested Rectangles– Cone Trees: 3D Interactive Animations– Hyperbolic Trees: Focus + Context
• Measures:– Papers, articles, patents, citations,…– Press releases, blog posts, tweets,…– Users, downloads, sales,…
