Tie Strength Talk

Wednesday, April 15th, 2009

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).

I recently returned from CHI in Italy. I’m happy with how the Network talk turned out, and I’m also happy with the sense of closure that came with it. I got a few requests to post the slides, so here are the slides in PDF and on slideshare.

I received some excellent questions and comments, and I enjoyed meeting a number of people after the talk. Thanks! I wonder if the video will actually be posted in the ACM digital library this year.

Now onto new work and more deadlines…
