7. Networks analyzed
• Chat network
• Nodes are the champions (people who had the grant to log into Taolin at April, 1st 2009)
• Edges are chat messages exchanged between champions
• Edge's weight is the discrete amount of chat messages between champions
• Profile views network
• Nodes are the champions (people who had the grant to log into Taolin at April, 1st 2009)
• Edges linked two champions each time a champion views another champion's profile
• Edge's weight is the discrete amount of these profile views
Both networks are directed and weighted.
For both of the considered networks we analyzed a timespan of two months from April, 1st to May, 31st 2009.
Profile-views network summary:
● 110 nodes, 760 edges, directed
● Number of components: 51
● Diameter: 6
● Density: 0.0634
● Reciprocity: 0.0872
● Average path length: 2.4954
8. Working Hypotheses
1. WH 1: Members of a specific group tend to chat more internally (with other
members of the group) than externally (with users who are NOT members of the
group). Members of a specific group tend to view profile more externally (with
users who are NOT members of the group) than internally (with other members of
the group).
2. WH 2: There is a correlation between "organizational centrality" and "network
centrality" in the platform usage. People who are very network central are the one
in the middle as "organizational centrality".
Working hypotheses have been computed and tested using igraph, an open source
library for complex network analysis (link: http://igraph.sourceforge.net/)
15. Future work
• Reorganize data in time sequences → Longitudinal analysis
• Analyse the impact of recruitment criteria (and also, a regime, no more
champions, but all the members of organization).
• Expand the datasets with
o Widget adoption (imitation effect)
o Cascade behaviors (innovation effect)
