Research on Structural Similarity of Case-Based Reasoning
范例推理结构相似性研究

Abstracting the problem of structural similarity of cases to be the similarity of graph, this paper proposes the similarity model, based on maximum isomorphic sub-graph, characterized with several levels of key nodes, which enables the comparison among cases of complex structures with simple numerical result. The model has provided the basis of comprehensive comparison among the partially-ordered attributes of different types. A example is employed to illustrate the whole similarity model.
