In this course we will explore the methods that facilitate Social Media analysis, with a focus on Facebook, Twitter and Foursquare. The course will begin with short tutorials on the different platforms, methods to access public data and common analysis methods. Participants will then be split into teams of 4-6 and under the guidance of the supervisors, define and design a hackathon project based upon their interests and personal goals. Starting environments will be provided. The students will then have 6-8 hours to implement their project with the help of the supervisors and will present their projects to the summer school participants the following day.

Social Computing?
§ “…any type of computing application in which software
serves as an intermediary or a focus for a social relation”
D. Schuler, Social Computing, CACM, 37(1) 1994.
§ “A social structure in which technology puts power in
individuals and communities, not institutions”
C. Charron, J. Favier, and C. Li, Social Computing: How Networks Erode
Institutional Power, and What to Do about It, Forrester Customer Report, 2006.
§ “Computational facilitation of social studies and human
social dynamics as well as the design and use of ICT that
consider social context”
F.-Y. Wang, D. Zeng, K. Carley, W. Mao, “Social Computing: From Social
Informatics to Social Intelligence”, IEEE Intelligent Systems, 2, 2007.

Data Access Permissions
There are 79 data access permissions in FB in 3 categories:
§ User Data Permissions
§ Friend Data Permissions
§ Extended Permissions
§ They regulate what you can and
cannot access

FB JSON Objects
§ Everything in FB is accessed via an ID
§ Users, Pages, Events, Comments, Posts, Shares, …
§ To view / access the JSON object for a FB entity:
§ https://graph.facebook.com/<EntityID>?auth_token=<auth_token>
§ Auth Token? à Access Token
§ An access token is an opaque string that identifies a user, app, or page
and can be used by the app to make graph API calls.
§ It is valid only for a predetermined period of time
§ A log out action will automatically expire an access token
§ Every time you log into FB, you create an access token
