ABSTRACT Web services are increasingly becoming the de facto implementation for the service-oriented architecture paradigm for enterprises due to their ease of use. Nevertheless, discovering these Web services is still hindered by many challenges that are partially attributed to shortcomings found in the discovery registry models (e.g., UDDI) used nowadays. These registries do not, for example, capture the rich information resulting from the various types of interactions between Web services. To address these shortcomings, and inspired by the conventional human social networks on the net, like Facebook and Twitter, we develop LinkedWS, a social networks discovery model to capture the different interactions that occur between Web services. Based on these interactions, specialized relationships are spawned and discerned. Examples of these relationships are collaboration and substitution. This paper describes LinkedWS and its potential, and reports on its implementation status.

    ABSTRACT: As enterprises turning to SOA, services-oriented business ecosystem (SOBE) has become an important pattern for the organization and management of the massive business services. At the same time, the emergence of Internet of Services (IOS) provides a business model in which service vendors and consumers can interact with each other via the Internet. This paradigm makes it possible that the services in SOBE are managed in an autonomous and coordinated manner. The challenge here is to organize these massive business services, coordinate, and federate them to achieve the benefits of SOA. To address these challenges, this paper presents BSNet, a framework on the basis of the service correlation networks to manage the SOBE. The model consists of a who-what-how service correlation network that captures the various relations in SOBE. Finally, a prototype system is developed, and a simulated case study is provided to show the expanded value of our network-based framework. Copyright (c) 2013 John Wiley & Sons, Ltd.

    ABSTRACT: This paper presents the development and evaluation of a \(\mathcal {Q}\) o \(\mathcal {SN}\) (standing for \(\mathcal {Q}\) uality of \(\mathcal {S}\) ocial \(\mathcal {N}\) etwork) model for social networks populated with Web services. These Web services are given the opportunity to select the networks in which they would like to sign in taking into account their concerns (in fact their providers’ concerns) like better protection to their details and better exposure to potential users. To support Web services selection, the \(\mathcal {Q}\) o \(\mathcal {SN}\) model is built upon four criteria including robustness, trust, fairness, and traceability. The computation of these criteria uses a cryptographic technique known as secure multi-party computation. Different experiments showing how the networks react to Web services’ actions (e.g., attack, join, and kick out) are also presented in the paper.
