Active players in a network tell the story: Parsimony in modeling huge networks
This study continues their work. Instead of exploring millions of online social activities, we suggest investigating the active users (as we define them) in their community and using their activity logs to build a partial network. This network of intensive users can depict the dynamics of a huge social network, in our case Yahoo! Answers intensive activities.
Barabási, et al. (2002) explored the connection between topology and network size on real–life networks. Twelve years later, our online Q&A social network study reached the same findings and conclusion: the partial network has several basic topological parameters that correlate with activity parameters of the entire social network and, hence, make it suitable for depicting the dynamic parameters of the huge network.
Since exploring online social lives is so interesting and time consuming, we believe that our findings can help the investigation of huge social networks. We call for further investigation of these findings and their implications.
