A Novel Approach to Improve Quality of Web Service Discovery

Web services have amazing role on the Web for supporting the distributed service-based economy on a global scale.There are number of web services are discovered but they face serval problems like isolation of services and lack of social relationship between related services has been known as reason for poor uptake. To overcome such kind of issues and to provide quality of web service we propose the isolated sevices into the global social service network to improve the services scalability on the global scale. we proposed linked social service-specific principles based on linked data principles for publishing a services on to the open Web as linked social services. Then, we consider a new framework for designing the global social service network based on linked social service-specific principles based on complex network theories. Further an approach is suggested to enable the exploitation of a global social service network, providing Linked Social Services as a Service

Social network-Based Framework for Users and Web Services Discovery

With the emergence of Web 2.0 and its applications, social networks have facilitated the discovery process of web services, a cornerstone to the development of service computing. Very recently, some frameworks have suggested adding a social element to services' description, discovery, binding and composition. By incorporating the social component in the Service-Oriented Architecture, web services become active entities that can form and be part of social networks. However, merging users and web services in the same social network and analyzing the influence of these entities (i.e., web services and users) on each other have not been examined in the previous proposals and yet to be investigated. In this thesis, we propose a new social network-based framework for analyzing the role and influence of users and web services in the discovery process. We advocate the idea of incorporating, not only social web services, but also social users in the discovery process by merging users and web services nodes in the same global social network. We first discuss the engineering process of such a social network that takes into consideration users and web services characteristics and the types of their interactions. Thereafter, we analyze those types of interactions that fall in one of two categories: web service discovery or user discovery. The goal is to involve social networks of users in the service discovery process and allow web services to be active parts by advertising and introducing themselves to other users. Simulation results show that the proposed approach provides an immediate and wider exposure for web services and makes the discovery easier and efficient

Using Social Networks for Web Services Discovery

International audienceSocial computing seems to be the new trend in Web applications development. FaceBook, Twitter, and LinkedIn are examples of a growing number of social applications that have reinforced the role of the Web as an inevitable communication means in this 21st cen- tury. FaceBook, alone, counts more than 350 million members in 2009, and more than 100,00 blogs are created daily. Social networking introduces a new dimension to the Web that goes beyond the exercise of connecting HTML pages; it opens up new forms of communication channels between people and between communities. Socializing over the Web lets people engage in various activities like looking for old friends, posting job announcements, and establishing new contacts. Parallel to the growing interest in integrating social elements into Web applications de- velopment, service computing rises as another alternative to this development. In response to challenges that modern enterprises face such as agility and competitiveness, today’s ap- plications need to be loosely coupled and capable to cross organization boundaries. Web services are a core technology that showcases the value-added of service computing to enterprises. A long list of standards and specifications (WS-*) sustain the adoption of Web services, besides the possibility of composing separate Web services to generate new added-value services. Someone would wonder the synergy that might exist between social computing and service computing. On the one hand, social computing allows to reflect relationships that people daily experience like friendship and dislike on automated structures known as social networks. On the other hand, service computing allows to develop applications as per the basic principle of “I offer services that somebody else may need” and “I require services that somebody else may offer”. Offering and requiring services raises issues such as how to advertise services to the external community, how to discover services with respect to needs, how to trust services when they are found, and how to replace services when they 1www.FaceBook.com, visited in Fall 2009. We address some of these issues by capturing the way the Web services interact with peers using social networks. Indeed services evolve in a dynamic environment in which they compete against peers so they can be selected, collaborate with peers so they can altogether work on complex users’ requests, substitute peers in case of failure so a high- level of availability can be achieved, just to cite a few examples of all the interactions that services initiate and hence, can be used for building these services’ social networks. Our work on social networks and Web services has two main goals: build Web ser- vices’ social networks and support Web services use these networks. We motivate our work further in the next section. After that a running example illustrates the nature of interactions between Web services. Details on what we refer to as social Web services are given prior to showing some experiments, discussing some related work, and drawing some conclusions
