Cloud computing, which can be described as a technology for provisioning computing infrastructure as a service, runtime platform as a service, and software as a service, is considered as a keystone for innovation in the IT area. However, a limiting factor to innovation through cloud computing...

As software vendors provide their software as a service (SaaS) and allow users to access the software functions via open interfaces, the innovation style has shifted from local innovation of a software user, to collective innovation of an entire system of users and software. This new innovation...

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...

Web2.0 users can create new services by combining existing Web2.0 services that offer open programming interfaces. This system of service composition forms a network, which we call the Web2.0 service network. A node of the Web2.0 service network represents a service. A link between two nodes...

Purpose- The purpose of this research is to analyze empirically the structure of the Web2.0 service network and the mechanism behind its evolution over time. Design/Methodology/Approach - Based on the list of Web2.0 services and their Mashups that is announced on www.programmableweb.com, a...

One of the notable trends in the software industry is that software vendors provide their software on a platform as a service. Software users consume those software services or compose new services by combining those existing software services. The software vendors, their services, software...

One of the important characteristics of Web2.0 is the collaboration between Web2.0 service providers. They allow users (i.e., providers, developers, consumers) to combine their services. The prerequisite for this collaboration is openness of the Web2.0 service system. Although the Web2.0...

Through the advancement of information technology, a new type of innovation could emerge. This innovation type suggests a leading company to open up its software service platform to customers as well as competitors. Many innovation studies have been performed in the past, in order to understand...

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...
