I am happy to announce that Ruth Sarig had successfully defended her thesis for her Master degree. The thesis, co-advised by Ran Wolff from Yahoo Research, is titled “Churn and Profile Deletion in Online Social Networks“.
Ruth’s thesis investigate profile deletion on social media. It provides an in-depth distinction between abandonment of social media and an active deletion of the profile. Ruth investigates current definitions of the factors that are correlated with various factors such as social influence, other privacy behaviors and different types of posting behaviors. The method relies on a large-scale data analysis (~6 Million blogs) from Tumblr, analyzing it with a logistic regression that controls for posting behavior and other variables. The second part of the methodology relies on creating logistic regression models for each group of users.
