Uncovering mechanisms of co-authorship evolution by multirelations-based link prediction
作者：
Highlights：
• The ways in which a hybrid mechanism jointly influences co-authorship evolution is clarified.
• The mechanisms are categorized into different groups and the contributions of different categorized mechanisms are computed.
• An improved meta-path based model called multirelations-based link prediction in heterogeneous bibliographic network is proposed.
• Experiments presented in Library and Information Science (LIS) show the co-authorship prediction accuracy is significantly improved with a hybrid mechanism denoted by a combination of predictors with weights.
