Abstract

Scientific collaboration is a significant behavior in knowledge creation and idea exchange. To tackle large and complex research questions, a trend of team formation has been observed in re-cent decades. In this study, we focus on recognizing collaborative teams and exploring inner pat-terns using scholarly big graph data. We propose a collaborative team recognition (CORE) model with a core + extension team structure to recognize collaborative teams in large academic networks. In CORE, we combine an effective evaluation index called the collaboration intensity index with a series of structural features to recognize collaborative teams in which members are in close collaboration relationships. Then, CORE is used to guide the core team members to their extension members. CORE can also serve as the foundation for team-based research. The simula-tion results indicate that CORE reveals inner patterns of scientific collaboration: senior scholars have broad collaborative relationships and fixed collaboration patterns, which are the underly-ing mechanisms of team assembly. The experimental results demonstrate that CORE is promising compared with state-of-the-art methods.
