| Abstract: | By collecting the data of bookcrossing website as data source in one month,this paper constructed the database model of books and the users,and then structured the bipartite graphs to describe the relationship between them.From the perspective of complex network,this paper analyzed and calculated the network related parameters,such as degree distribution,clustering coefficient,the average path length,node strength distribution,act degree distribution,act size distribution and node interest,and the conclusion is that the book-crossing network model has scale-free characte-ristics and small-world network characteristics in the same time. |
