I am working in paper and i need user profile data-set including location or check in dimension in any social network like Facebook. It is to better to be used by previous papers or known datasets.
The best solution would be to develop an application and have the Facebook users authorize it. You would get very limited data otherwise (their posts in public groups, fan pages only).
You could test the API to see what data you would get using the following link
I suspect that obtaining this information without user authorization will be difficult. Social network information is pretty close hold. If you get it through an app, API, etc., then you are limiting your population, with resultant effect on external validity if you desire the information for academic research. When I worked on online social networking for my dissertation, I had to rely on self-reported survey data, as I found all other avenues closed.
