Relationships make social media social. Yet, different relationships play different roles. For example, one's Facebook friend list may include their college professor, their grandmother, and an acquaintance from the dentist's office. In this talk, I begin by discussing the presentation of relationships in social media. I emphasize how text is used and how it can be used to shape identity and to infer relationships from this presentation.
Using such textual cues, I will present an approach to predict relationship strength from Facebook pages and discuss how this may generalize to other social media sites. I conclude with a discussion of what this means for the design of social media - in particular, new interaction techniques for social zooming.
