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...

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 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...

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 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...

As IT technology advanced, a new style of innovation emerged, in which a leading innovation company invites end-users to its open software service platform. With respect to this type of innovation, a lot of innovation studies were performed to understand the structure of the interaction among...

Service networks can be considered to be open innovation systems. It has led to research on the structure of these networks, concentrating on the static network topology and its effect on innovation. However, the research misses the changes of network positions over time. In this paper, we...

While the h-Index and the g-Index (as the major indices for quantifying the academic performance of researchers) take into consideration the citation count of publications, some other important indicators of research output (i.e. the number of authors per paper, lead author, year of publication)...
