Runda Liu, Hui Zhao · 2011
Acquire the metadata of shared scientific data of Earth System Science on the Portal of Chinese Science and Technology Resource, extract field keyword for analysis, then use Network Workbench Tool (NWB Tool) for keyword co-occurrence network analysis. By conducting community detection and network visualization on 5 sub-fields of the acquired data, this paper presents the status and features in each selected sub-field of shared Earth System Science data resources under China Scientific Data Sharing Project (SDSP), this work shows that network analysis and visualization tools of NWB provide effective means for data resource measurement and analysis.
