  1. A Social Network Perspective on Mass Collaboration Systems Gerald C. Kane and Sam Ransbotham Carroll School of Management

  2. Wikipedia’s Wikiproject Medicine • Considerable research investigating collaboration on WP. • Most have treated articles as independent. • Working on multiple articles, authors transfer information from one article to another. • Examine network of 2M+ revisions to 14.5K medical articles on WP. • Create 14.5K x 14.5K incidence matrix of articles & authors. • Test whether number of authors, degree centrality, eigenvector centrality associated with article quality (Constant et al. 1996). • Good support for our hypotheses. Suggests WP is knowledge network not encyclopedia of independent articles. • Dependent variable (article quality) validated by 4th year medical students. 82% IRR, 90% Agreement with WP.

  3. We want your input • Current research is only first project in research program. • Use 3-month moving window to take advantage of longitudinal data. • Panel or cumulative network? Effect on eig. centrality measure? • Project 2: Does collaboration lead to quality, or does quality lead to collaboration? • Simultaneous equation panel model to evaluate causation. • Project 3: How does the network change over time? • Curve-fit network features over time to identify archetypical evolution patterns. • Ideas on how to address these or other projects are welcome! • Methodologically/ econometrically/ computationally
