SOA and cloud computing have brought new opportunities for the long expected agility, reuse and the adaptive capability of IT to the ever changing business requirements and environments. But due to the immature nature of the rapidly evolving technologies, especially in the areas of security, service or information integrity, privacy, quality of service and their possible detrimental consequences, many enterprises have been hesitating to make the shift. This paper adopts the concept of insurance and establishes a framework and the supporting reference model for cloud computing. We utilize the value-at-risk (VAR) approach to establish several appropriate mechanisms, and use a set of measurable metrics. Those quantitative or qualitative metrics can be applied as the basis for the business value and risk assessment, and eventually for insurance premium and compensation calculation for the failures of the services offered in Cloud environment. This model can also establish a potential new innovative market branch for the insurance industry.

In this paper, we propose an approach for approximate matching of OWL-S process model. We also propose a similarity measure that captures structural and semantic differences between two process models. To do so, we reduce the process matching to a graph matching problem and we adapt existing algorithms for this purpose.

The DynaSOAr framework presents a wholly service-oriented approach to grid and Internet-based computing that makes a clear and explicit separation of concerns between service-provision and resource-provision for each service invocation. The separation allows the dynamic deployment of code at runtime, in the form of a service implementation, between a service provider and an explicit resource provider. This paper presents work in progress towards an integrated tripartite security model and framework that enables the security constraints of each engaging party to be expressed, propagated, unified and enforced as part of a DynaSOAr service invocation.

Service composition is nowadays mainly seen as a once-for-all activity. Supporting a dynamic service world, where both available services and needs may change, requires runtime adaptive features for service composition. In this paper we propose a repair technique for internal composition adaptation, as opposed to external adaptation. Moreover, setting up our proposal in the planning framework, we compare our repair technique with reference to re-composition, that is re-planning.

In this paper, we propose a time-sensitive probability skyline (TPS) approach to recommend services with uncertainty. We project services to n-dimensional data space and recommend services in TPS. Experimental evaluation on real data shows the great performance of TPS in service recommendation by comparing the experiment result with results of other approaches.

Efficient and accurate discovery of user desired Web services is a key component for achieving the full potential of service computing. However, service discovery is a non-trivial task considering the large and fast growing service space. Meanwhile, Web services are typically autonomous and a priori unknown. This further complicates the service discovery problem. We propose a service community learning algorithm that can generate homogeneous communities from the heterogeneous service space. This can greatly facilitate the service discovery process as the users only need to search within their desired service communities. A key ingredient of the community learning algorithm is a co-clustering scheme that leverages the duality relationship between services and operations. Experimental results on both synthetic and real Web services demonstrate the effectiveness of the proposed service community learning algorithm.

Service-oriented Architectures support the provision, discovery, and usage of services in different application contexts. The Web Service specifications provide a technical foundation to implement this paradigm. Moreover, mechanisms are provided to face the new security challenges raised by SOA. To enable the seamless usage of services, security requirements can be expressed as security policies (e.g. WS-Policy and WS-SecurityPolicy) that enable the negotiation of these requirements between clients and services. However, the codification of security policies is a difficult and error-prone task due to the complexity of the Web Service specifications. In this paper, we introduce our model-driven approach that facilitates the transformation of architecture models annotated with simple security intentions to security policies. This transformation is driven by security configuration patterns that provide expert knowledge on Web Service security. Therefore, we will introduce a formalised pattern structure and a domain-specific language to specify these patterns.

We propose an integrated framework that manages changes in long term composed services. The main procedure of change reaction is presented. One of the most challenging research issues of change management is how to automate the process of change reaction. To address this issue, we propose a semantic support, which centers around a tree-structured Web service ontology. The ontology is expected to provide sufficient semantic for change reaction. We propose a set of algorithms for efficiently querying semantics from the ontology. We conduct a set of experiments to evaluate the performance of the proposed algorithms.

Quality-of-Service (QoS) is widely employed for describing non-functional characteristics of Web services. Although QoS of Web services has been investigated in a lot of previous works, there is a lack of real-world Web service QoS datasets for validating new QoS based techniques and models of Web services. To study the performance of real-world Web services as well as provide reusable research datasets for promoting the research of QoS-driven Web services, we conduct several large-scale evaluations on real-world Web services. Firstly, addresses of 21,358 Web services are obtained from the Internet. Then, invocation failure probability performance of 150 Web services is assessed by 100 distributed service users. After that, response time and throughput performance of 5,825 Web services are evaluated by 339 distributed service users. Detailed experimental results are presented in this paper and comprehensive Web service QoS datasets are publicly released for future research.
