Topic: Likes-R-Us: Understanding and Protecting Likes in Social Media

The recent dramatic increase in the usage and prevalence of social media has led to the creation and sharing of a significant amount of information in various formats. When it comes to information consumption, people are not only accessing and appreciating published and shared contents, but also interacting with them by adding comments or pressing a Like button (or expressing other relationships similar to Like in nature such as “+1” in Google+, “re-pin” in Pinterest, and “favorite” in Flickr). As one of popular activities in social media, in particular, pressing a Like button toward published contents can be interpreted as an indication of one’s shared interests to the contents or the original posters. Therefore, such Like activities form relationships and networks among people, raising interesting questions about their unique characteristics and implications. In this talk, I will present some of recent findings from the “Likes-R-Us” project ( at Penn State, identifying novel relationships from Like activities, understanding different age groups better through the lens of Likes, and uncovering fake Likes to maintain healthy eco systems.

Research Seminar

Social Networks Working Group

Friday, March 10, 2017

10:30 a.m.-12:30 p.m., lunch provided

Room 310 (Samuel Bronfman Building – 1001 Sherbrooke Street West)

The seminar features two 40-minute presentations followed by informal discussions over lunch.

Laura Doering, Assistant Professor of Strategy will be presenting her research (co-authored with Aruna Ranganathan at Stanford GSB) entitled:

“Not on the Same Page: Status Barriers to State-Private Ties in Economic Development.”

The project examines how relationships between state and private sector actors (which are assumed to be relatively homogeneous) can be shaped by status biases, and how this impacts economic development.

Brian Rubineau, Associate Professor of Organizational Behavior will be presenting his research (co-authored with Yisook Lim, Mike Neblo, & David Lazer) entitled:

“Charismatic bridging: Network state vs trait antecedents of leader emergence.”

The project conducts a within-individual analysis to identify the network antecedents of attaining leadership positions. This analysis examines individual, dyadic, and triadic network predictors involving both positive and negative ties.

All are invited to attend the seminar.

Montreal-area PhD students with interests in social network research are particularly encouraged to attend.
