Social computing, Analysing Social Media: Theory and Hackathon
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.

Learning Outcomes of the Session to learn the basics of analysing
social media via a hands on session with Facebook, Twitter or
Foursquare to gain hands on experience of accessing data, creating
apps and running analysis methods to gain experience in team-based
rapid prototyping 11

Token? 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 More info:
