Trust is a critical issue in e-commerce and e-service environments. In some applications (such as eBay), the trust management mechanisms have been introduced to provide valuable information to buyers prior to placing orders and making payments. Meanwhile, the trust issue is also actively studied in the research community. However, most studies and applications focus on approaches that result in a single trust value to represent the trust level of sellers or service providers. Such a simple trust evaluation method may not be able to depict the trust history exactly and may leave misleading information to service customers. In this paper, we present a novel approach of trust vector consisting of three values to reflect the trust level with more indications.

Composing adaptive and self-managing Web services needs plug-and-play architecture so that the deployment of control components does not require changes made to the Web services and the host middleware platforms. This is especially challenging for Web services running on COTS middleware platforms, such as Microsoft.Net. In this paper, we propose an architectural solution that introduces a management proxy between adaptive control components and Web services. The management proxy can be customized and seamlessly integrated with a COTS middleware platform by leveraging the existing middleware mechanisms. This solution enables dynamically composing adaptive Web services on COTS middleware without stopping its services. We demonstrate this architecture by a realistic Web service application built on .Net Windows Communication Foundation (WCF). The performance overhead incurred by this architecture is measured, and the results validate that our solution is efficient in terms of performance and flexibility.
组合自适应和自管理的Web服务需要即插即用的体系结构，这样控制组件的部署就不需要对Web服务和主机中间件平台进行更改。这对于运行在COTS中间件平台(如Microsoft.Net)上的Web服务来说尤其具有挑战性。在本文中，我们提出了一个在自适应控制组件和Web服务之间引入管理代理的体系结构解决方案。通过利用现有的中间件机制，可以定制管理代理并与COTS中间件平台无缝集成。此解决方案支持在COTS中间件上动态组合自适应Web服务，而无需停止其服务。我们通过一个基于。net Windows Communication Foundation (WCF)构建的实际Web服务应用程序来演示这种体系结构。测量了该体系结构产生的性能开销，结果验证了我们的解决方案在性能和灵活性方面是有效的。

All words are used in books, in which each are organized into a category through a library classification system. Therefore, words used by bloggers are also written in books, which in turn are categorized into specific categories. If a blogger uses a particular word often, we can anticipate that the blogger will have interest areas coinciding with the related book categories. This paper suggests that bloggerspsila interests can be known through extracting keywords from blog entry titles and using book classification schemes. Because there were instances in which the keywords alone did not provide adequate information, the Naver (Korean search engine) related keywords search function was used because of its collective intelligence properties. During the experiment, test subjects picked the blogs and entry titles, which were analyzed using the 'Naver OpenAPI'. The results show that it is possible to know a blogger's interests using blog entry titles and book classifications.

Despite the benefits those communities FM radio broadcasting services provide to their listeners, more than half of the community stations in Japan are struggling financially. This situation has arisen because the Internet has attracted advertising revenue away from radio broadcasting channels. One way to revive local FM radio broadcasting is by adding new representation function to radio signals. It is designed for many listeners to share the same information simultaneously. On the other hand, while the Web provides a variety of content, its ability to broadcast is inferior to that of TV or radio broadcasting. Combining radio broadcasting and the WWW provides a new broadcasting media. The control signals used for accessing the Web are put onto radio sound by using Acoustic OFDM technology. We developed and evaluated such a broadcasting system.

Today, multimedia system are still widely realized as monolithic systems. But building such applications using Service-Oriented Architectures - especially for the Processing and Delivery of continuous Multimedia data streams - has been a controversial topic since years. As a result, applications in the multimedia domain cannot yet benefit from Web service architectures. Thus, building and maintaining large-scale multimedia applications remains a difficult, costly, time-consuming and challenging problem. In this paper we present our approach for building large scale multimedia systems and compare it with the current state of the art, concentrating on the selection and validation of multimedia service composition.

The dependability of composite services is largely affected by their constituent Web services. Composite services have to operate in an open and dynamically changing environment in order to leverage the best performing services available at the moment. Hence, there is the need for an efficient mechanism to provide reliable service rankings. In this paper we present a novel, generic, and customizable reputation infrastructure to automatically and transparently monitor the execution of composite services, taking both functional and non-functional properties into account. The experienced Web service quality-of-service is communicated to a configurable reputation mechanism that publishes service rankings. Our reputation infrastructure supports notifications upon changes in service reputation, enabling self-tuning and self-healing properties in the execution of composite services. We implemented our architecture using standard technologies, such as BPEL and JavaEE. Performance measurements show that our infrastructure causes only moderate overhead.

Interest in service oriented architecture (SOA) is rapidly increasing in the business world due to the many benefits it offers such as reliability, manageability, reusability, flexibility, efficiency, and interoperability. There are many security technologies and models being developed for SOA. They implement or encode specific aspects of authentication, authorization, encryption, trust, and access control respectively but none of them was entirely devoted to integrity. In this paper we propose service Clark-Wilson integrity model (SCWIM), a top down integrity model for SOA capable of describing sufficient conditions to protect data integrity in any SOA implementation. Based on the original Clark-Wilson integrity model, our model can form the basis for system security audits and assist SOA architects in developing systems that protect data integrity, as well as providing guidance for evaluating existing SOA systems.

QoS-aware service composition intends to maximize the QoS of a composite service when selecting service providers. This paper proposes a service composition scheme that uses a combination of Integer Programming, case-based reasoning, and, genetic algorithms techniques. The scheme reduces the service composition costs by reusing existing compositions. Experiments show that, compared with solutions purely based on Integer Programming, the proposed scheme is effective in reducing the time for carrying out service composition.

In order to co-ordinate multiple resource providers in grid environment to meet a common objective, support for negotiation is needed to establish a contract between the user and the resource providers that clearly states the QoS required, restrictions on resource utilization and penalties during violation of the objective. Strength of the negotiation process mainly depends on the selection of resources for negotiation. Currently, no grid meta scheduler supports SLA negotiation. We propose a deviation based resource ordering algorithm (DRS) that orders and selects the resources for negotiation based on their deviation value computed from the parameters in the job request against their current availability in the resources. Also, we propose mutual agreement protocol (MAP) to negotiate with resources in order to get their commitment against the job request. We simulate this negotiation process and compare it against gridway meta scheduler that shows improved performance in terms of average SLA creation time, success rate and throughput.

Dynamic collaborations involve contributed resources across the organisational boundaries that are subjected to different set of policies. The management of such resources for dynamic collaborations including negotiation, validation, instantiation and termination is difficult. Existing approaches for collaborations using Web Services such as WSLA are designed to deal with scenarios involving two parties: a service provider and a service consumer. These approaches do not scale well to multiparty nature of dynamic collaborations. To address this problem, we propose a framework for a language called Web Service Collaborative Context Definition Language for dynamic collaborations. The language itself has been defined using XML Schema and has been implemented in a dynamic collaboration platform.
