Living deliverables of the research project STELLAR are analysed with respect to exposed editing activity -- beyond the deadline of actual delivery.

1. Living deliverables: angels or zombies? 2ndInternational Workshop on Research 2.0, September 28, 2010, Barcelona, Spain Fridolin Wild, Thomas Ullmann The Open University

2. Living Deliverables Deliverable:pre-defined, tangible, and verifiable work product; report on progress against tasks Living deliverable: continuously edited with lively activity beyond official delivery deadline;wiki >> 2 … prior work … method … analysis … outlook

3. Sunword Glyph (Arazy et al., 2010) Detailed Glyph (Arazy et al., 2010) Prior Work WikiChanges: Sparklines (Nunes et al., 2008) Focus on individual articles History Flow (Viegas et al., 2004)

4. Prior Work (2) Corporate Knowledge Sharing analysed with Sonivis (Baumgrass et al., 2008) Different scope or different wiki use Revert Graphs (Suh et al., 2007) Meso-Zoom Analysis (Jesus et al., 2009)

5. Life after deadline Angel:cheerful editing activity of a coherent set of pages of a deliverable also after deadline Zombie: Low or no editing activity after deadline 5

6. Method of Analysis Data extraction from latest changes feed and versioning history in database Statistics on revision histories Social Network Analysis using revision history Co-authorship networks: two people edit the same page = co-authorship: IMA,Tx IMTA,T Bipartite author-page networks: person edits page = directed edge from person to page: AMA∧P, A∧P

7. Observed Living Deliverables 7 Average: 22.7 users, 3 820 page views, selected from 14 living deliverables, thereby excluding small group works and obvious zombies (no editing activity from the first day)

8. Cumulated Edits over Lifetime 8

9. Co-authorship network of d6.3 9

10. Co-Authorship net w/o ‘Home’ 10

11. Page-author net before deadline 11 D6.3

12. Page-author net after deadline 12 D6.3

13. Other deliverables after deadline D7.1 D6.2 D1.1 D1.2 became a ‘zombie’ (in the period of analysis – might be an angel by today)

14. 14 Discussion Limit: Don’t mistake wiki co-authorship for overall collaboration on a deliverable Limit: Small set of wikis investigated Found: Way to make activities more transparent Found: There are phases in life Found: Shift in focus after delivery Outlook: differentiation of editing types Outlook: animation over time Outlook: reflection tool about collaboration?
