The CI-KNOW system mines the knowledge network associated with research communities' use of cyberinfrastructure tools, using provenance information and relational metadata from a metadata store through Tupelo 2 to create context-specific recommendations for CyberCollaboratory users. A network navigation portlet allows users to locate colleagues, documents, data or analytic tools in the knowledge network visually and to explore their networks. An internal auditing portal offers administrators diagnostics for assessing the growth and health of the entire knowledge network.
