基于科学数据的合作网络研究——以ClinicalTrials.gov临床试验数据为例

Purpose/significance] Based on the scientific data, we constructed a new collaboration network and compared with cooperative network of traditional publications. By exploring the differences of the two collaboration network from the perspective of network analysis, this paper provided reference for scientific data management. [Method/process] Taking clinical science database of ClinicalTrials.gov website as an example, this paper used crawler technology to capture the metadata of traditional publication and clinical trial research. Then, based on these two kinds of metadata, this paper constructed different cooperative networks respectively. Finally, it used complex network analysis to explore these networks to compare the similarities and differences between two networks. [Result/conclusion] Scientific collaboration network extracted metadata from a scientific repository and publication could provide richer and more accurate information of collaboration than just using metadata from publications alone.This paper reveals the importance of scientific data management and open sharing.
