A Survey Paper on Novel Approach to Improve Quality of Web Service Discovery

Web services have vital role on the Web for supporting the distributed service-based economy on a global scale.There are number of web services are available today but they face serval problems like isolation of services and lack of social relationship among related services has been known as reason for poor uptake.To overcome such kind of issues and 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 introduce linked social service-specific principles based on linked data principles for publishing a services on the open Web as linked social services. Then, we consider a new framework for constructing the global social service network based on linked social service-specific principles based on complex network theories. Further an approach is proposed to enable the exploitation of a global social service network, providing Linked Social Services as a Service

Composite Web Services Formation Using a Social Network of Web Services: A Preliminary Investigation

A composite Web service, such as arranging a travel to a conference, can be viewed as a project team that is comprised of several members who want to collaborate in order to accomplish a specific goal. In this work, we propose an algorithm for searching a social network of Web services in order to select an effective set of Web services that can collaborate in order to attain the main goal of the composite Web service at hand. Ultimately, the selection algorithm takes into consideration the set of functions that each Web services member possesses, e.g., hotel booking, car rental, etc., and the communication cost among these members. Our goal is to secure all the functions required by the composite Web service yet minimizing the communication overhead. The preliminary design of the experiments and the future work are described. © 2011 Published by Elsevier Ltd

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

Business Reputation of Social Networks of Web Services

© 2015 The Authors. Published by Elsevier B.V. This is an open access article under the CC BY-NC-ND license. This paper introduces a set of criteria that are used to establish the reputation of a social network from a business perspective. This network is populated with social Web services. Compared to regular Web services, social Web services establish and maintain networks of contacts, count on their (privileged) contacts when needed, etc. These criteria are membershipCost, demandLevel, satisfactionLevel, and retentionLevel, and assist a social Web service in selecting the best social network in which it will sign up. Similar criteria have been defined in the past with emphasis on the security perspective of a social network. A set of simulations conducted over an in-house built Java testbed, are also presented in the paper with focus on analyzing three aspects: profit of network, quality of network, and profit versus quality of network

Towards a user-centric social approach to web services composition, execution, and monitoring

This paper discusses the intertwine of social networks of users and social networks of Web services to compose, execute, and monitor Web services. Each network provides details that permit achieving this intertwine and thus, completing the three operations. A user social-network is used to advise users on the next Web services to select based on their peers’ experiences, whereas a Web service social network is used to advise users on the substitutes to select in case a Web service fails, for example. To make the intertwine of these social networks happen, three components are developed: composer, executor, and monitor. The social composer develops composite Web services considering relations between users and the ones between Web services. The social executor assesses the impact of these relations on these compositeWeb services execution progress. Finally, the social monitor replaces failing Web services to guarantee the execution continuity of these composite Web services. A running example and a prototype illustrate and demonstrate the intertwine of these social networks, respectively.Zakaria Maamar, Noura Faci, Quan Z. Sheng and Lina Ya

Sla Management in a Collaborative Network Of Federated Clouds: The Cloudland

Cloud services have always promised to be available, flexible, and speedy. However, not a single Cloud provider can deliver such promises to their distinctly demanding customers. Cloud providers have a constrained geographical presence, and are willing to invest in infrastructure only when it is profitable to them. Cloud federation is a concept that collectively combines segregated Cloud services to create an extended pool of resources for Clouds to competently deliver their promised level of services. This dissertation is concerned with studying the governing aspects related to the federation of Clouds through collaborative networking. The main objective of this dissertation is to define a framework for a Cloud network that considers balancing the trade-offs among customers’ various quality of service (QoS) requirements, as well as providers\u27 resources utilization. We propose a network of federated Clouds, CloudLend, that creates a platform for Cloud providers to collaborate, and for customers to expand their service selections. We also define and specify a service level agreement (SLA) management model in order to govern and administer the relationships established between different Cloud services in CloudLend. We define a multi-level SLA specification model to annotate and describe QoS terms, in addition to a game theory-based automated SLA negotiation model that supports both customers and providers in negotiating SLA terms, and guiding them towards signing a contract. We also define an adaptive agent-based SLA monitoring model which identifies the root causes of SLA violations, and impartially distributes any updates and changes in established SLAs to all relevant entities. Formal verification proved that our proposed framework assures customers with maximum optimized guarantees to their QoS requirements, in addition to supporting Cloud providers to make informed resource utilization decisions. Additionally, simulation results demonstrate the effectiveness of our SLA management model. Our proposed Cloud Lend network and its SLA management model paves the way to resource sharing among different Cloud providers, which allows for the providers’ lock-in constraints to be broken, allowing effortless migration of customers’ applications across different providers whenever is needed

Social purchasing and the influence of social networking: a conceptual view

Internet has enabled businesses to offer their merchandise through web-based applications, of which recent phenomenon includes online social networks (OSNs). This paper studies the influence of OSNs through the lens of perceived trust (PT), social norm (SN), user satisfaction (US) and perceived behavioral control (PBC) to find out how these influence participants of OSNs continuance buying intention. A model of IS continuance intention of web-based application was developed to test the above factors. The results show that trust in OSN is based mainly on the degree of the social relations that users have with their vendors, because they are members on the network, on top of their experiences of web service use. US was influenced by PBC, while US also influenced SN and PT with PT exhibiting a strong relationship with SN. Keywords: continuance intention, OSN, participants, purchasing.

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
