摘要
A hierarchical structure extraction approach based on agglomerative clustering was proposed, and a density estimation based on topological structure was designed. By conducting the hierarchical aggregation on layers of hierarchical structure, the characteristic of clusters could be measured. The empirical study conducted on a large real data set indicates that the model and measures are interesting and meaningful, and the algorithms are effective and efficient in practice.
