I found an interesting presentation about modelling user interactions in online social networks. It was posted four days ago by a collaborator of the Seoul National University and presented at the Asian workshop of social web and interoperability in December.
The presentation looks at the definition of online friends and the interaction between (social) users.
The authors divide the social networks according to four criteria and axes: functional (like LinkedIn), user profile focused, entertaining and interest focused.
Then they look at the interaction and social semantic information spaces.
The interaction models and the questions that are asked and answered in the presentation are not your average easy to consume social network tips, but take a look it, there are really some interesting things in it if you take your time to view the presentation and think about some ideas in it.
Not for social network newbie’s!
