Scientific Research Collaboration Hypernetwork Modeling and Node Importance Measuring

In research collaboration organizations, to evaluate the contributions of researchers and then to identify core researchers is an important issue. Network is a basic model to investigate this question, but with increasingly complex collaborative behavior, it shows limitations for semantic representations. In this paper, by introducing hyper network, a more powerful modeling tool than traditional network to construct scientific research collaboration hyper network (SRCH), we measure the importance of researchers in two aspects as collaborative relationship structure and collaborative achievement value. An additive weighting method with adjustable parameters is utilized to integrate the evaluations into a synthetical one. Data instance verifies that our measuring method for SRCH is reasonable and effective.
