1 What Researchers Want Cody Dunne Dept. of Computer Science and Human-Computer Interaction Lab, University of Maryland cdunne@cs.umd.edu STM 3 rd Master Class November 7-9, 2011 Adelphi, MD, USA Links from this talk: bit.ly/stmwant 1

2 Researchers want to… 1.Find a specific paper 2.Explore a research area 3.Do retrospective analysis 4.Share their results 2

3 1. Find a specific paper Metadata or PDF? From memory (search) From reference list – DOI/URL – Search 3

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 4

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 5

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 www.cs.umd.edu/hcil/ase 6

7 7

8 Reference management & grouping 8

9 Citation network overview Communities, outliers, invalid data 9

10 Statistics & visualization Network statistics – Degree – Betweenness – Closeness – Pagerank Attributes – Year – Downloads – Citations – References 10

11 Field evolution 11

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 12

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 13

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 stick.ischool.umd.edu 14

15 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,… 15

16 Treemaps: nested rectangles www.cs.umd.edu/hcil/treemap-history 16
