Predicting Structural Hole Spanners in Online Social Networks Using Machine Learning
Constructed location-based social graph from log file of QingyunGo. Found out the most effective algorithm for the identification of top-k structural hole spanners (SHS) on our dataset. Investigated the factors that impact spatial and temporal features of QingyunGo check-ins. Utilized machine learning algorithms to evaluate the influence of factors and predict the dynamic development of SHS.
