内容:

Knowledge Organization Systems (KOS) (e.g., classification schemes, taxonomies and ontologies) have long been established as a tool to represent organized interpretation of knowledge structures. Various types of KOS such as NSFC discipline tree for research projects, subject categories for research publications, classifications schemes for research patents are constructed for research management purpose. However, the incompatible KOS, together with information proliferation in the Big Data Era, impose great challenges for effective research management from heterogeneous information. My research aims to facilitate interoperability among heterogeneous research information sources by leveraging metadata analysis and social network analysis. In the published paper in Scientometrics, a novel multi-faceted method was designed to measure the similarity between two classes based on three important facets, namely descriptors, individuals, and semantic neighborhood. The method was evaluated based on two main KOS that need mapping for information management and policy-making in NSFC, and shown satisfying results. The interoperability among heterogeneous KOS was resolved to enhance the access to heterogeneous scientific resources andthe development of appropriate research analytics policies.
