STACY: Um Novo Algoritmo para Automaticamente Classificar a Força dos Relacionamentos ao Longo dos Anos

Understanding the relationships between people in a social network and measuring their strength over time are interesting problems with distinct applications.

Our results show: such classes represent different behaviors, and STACY identifies strong relat...
