Using the scientific papers and their authors, we have established a supernetwork of scientific collaboration between researchers and papers. In the supernetwork, researchers are not only pair connected if they have coauthored one or more papers, but also connected to the papers if they co-published the papers. Generalization the concept of complex network to the supernetwork is studied to analyze the topological of the supernetwork. Here we study a degree central with coefficients to measure the importance of the researcher node. Finally, by utilizing the real-world data, we applied these characteristics to find out the important researchers in the supernetwork.
