Over the past decade, social networks have become a massive engine for generating new text, image and video content. In this talk I will show how the creation and curation of user-generated content can be seen as a distributed human computation and will describe a number of machine learning and data analysis approaches to answer three high level questions:
- What can social network interactions tell us about ourselves?
- How can we coordinate disparate and independent user actions to learn new information about the content being generated?
- How can we adapt large “internet-scale” systems such as today’s social networks to user characteristics and workloads presented?
The talk will be loosely based on a series of papers published over the past few years at the The Web Conference (WWW) and the AAAI International Conference on Web and Social Media (AAAI ICWSM).
