Study of the Port´s Concept System Based on Knowledge Ontology

As the terminal of multi-transport, the connecting points between ships and other transport vessels and the nodes of modern logistics and doors to trade, the concept of port should be a regional concept with economic characters and social characters. And the hierarchical denotation of port knowledge is given. With the development of knowledge management, it is worthwhile to analyze the correlations among related concepts, study on the construction of knowledge structure and develop an up-to-date integrated system. Based on Molecular Biological, coupling unit is taken as the basic function of port. According to Mode analysis Theory, the concept of port has been formalized. The new concept constructs multi-dimension conceptual architecture including both the economic factors and the regional factors.
