摘要

China has a huge volume of historical resources on its contemporary history. However, the organization of these historical resources is not satisfactory. On the basis of related studies, this paper proposes a method, which is called 'Mining down, Organizing up', to represent and organize the historical knowledge on contemporary China. Based on a contemporary Chinese historical ontology, this method extracts knowledge objects and facts from unstructured historical text items, forms a historical knowledge network on contemporary China, and realizes multidimensional knowledge organization at a higher level based on the relations such as time, subclass, hierarchy, and statistics. Based on this method, we represented and organized the historical knowledge on contemporary China from text resources, and developed a system to implement historical knowledge visualization, reorganization and other new applications including knowledge maps, relevance analysis, and national historical fact reconstruction etc. This study shows that the 'Mining down, Organizing up' method can realize the fine-grained representation of the historical knowledge on contemporary China and innovative application of knowledge organization based on historical knowledge objects. It can be used as a kind of new knowledge representation and organization methods applicable in other fields.
