Tie Strength Talk

This was my favorite CHI to date. It was nearby — big plus. I met a lot of great people, and the conference moved primarily out of the paper sessions and into the hallways for the first time. I gave the predicting tie strength talk to a nearly full house, and was very happy with how warmly the work was received. Here are the slides in pdf and at slideshare.

My main argument is that we can model tie strength with quite high accuracy using only the data left behind in social media. In this case, I used Facebook data to predict relationship tie strengths provided by our participants. I then argue that we could use this relationship model to do smart things like provide good defaults for privacy controls (the illustration in the slides near the end).
