The mechanism is based on the previous work about a context-based formalism-Context-SHOIQ （D ＋ ） DL, which is used for explicitly representing context of ontology by adopting the description logic and the category theory. The formalism is extended by adding four migration rules （InclusionRule, SelectionRule, PreferenceRule, and MappingRule）, that are used to specify what should be imported into the IntegrativeContext, and three related contextual integration operations of increasing interoperability （import, partial reconciliation, and full reconciliation）. While not exhaustive, the mechanism is sufficient for solving the five types of semantic irreconcilable problems that are discussed, and favors integration of ontologies from one context to another.展开更多

This paper focuses on different methods of RCCL transfer based on stakeholder analysis and three case studies including models from Guangdong, Wuhu and Chongqing. The main finding is that all three models improved resource allocation efficiency and intensive utilization of RCCL through land and capital transfer. Each model built different interest coordination mechanisms among stakeholders, suited to different regions and cases. The Guangdong model is suitable for an economically developed region. The Wuhu model is suitable for developing regions in central China while western underdeveloped regions in China can adopt the Chongqing model. The policy implication is that better policy making for the promotion of RCCL transfer in China should consider regional characteristics as well as the economic development context.展开更多
