Collaborative Team Recognition: A Core Plus Extension Structure
This work addresses the need to understand team formation in scientific collaboration, but it appears incremental as it builds on existing methods for team recognition in scholarly data.
The study tackled the problem of recognizing collaborative teams in large academic networks by proposing a CORE model with a 'core + extension' structure, which effectively identified teams with close collaboration relationships and revealed patterns such as senior scholars having broad and fixed collaborations.
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 recent decades. In this study, we focus on recognizing collaborative teams and exploring inner patterns 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 simulation results indicate that CORE reveals inner patterns of scientific collaboration: senior scholars have broad collaborative relationships and fixed collaboration patterns, which are the underlying mechanisms of team assembly. The experimental results demonstrate that CORE is promising compared with state-of-the-art methods.
