Service providers that own Web2.0 services allow Internet users not only to access their Web2.0 services but also to create new Web2.0 services (mashups) based on theirs. This creation of mashups generates the Web2.0 service network, in which a node represents a Web2.0 service and a link between...

One of the most important properties of self-organized networks is their scale-free property. Prior research proved empirically and theoretically that scale-free networks emerge under the preferential attachment rule. However, a few empirical studies also show that empirical networks diverge...

As empirical studies have found that large complex networks (e.g., WWW) are scale-free, the preferential attachment model is commonly applied to generate this network topology. This model assumes a node with higher degree is more likely to gain a new link, and ignore node attributes except the...
