Knowledge sharing over social networking systems: a case study of Ecademy data

•
•
T
tanguy

1. The document discusses knowledge sharing over social networking systems and analyzes data from the social networking site Ecademy. 2. The Ecademy data showed a power law distribution structure typical of social networks and small world properties with short paths between users. 3. A survey of Ecademy users found that face-to-face relationships positively influenced relationship strength and knowledge sharing, though the site mainly facilitated weak relationships.
