TL;DR: This paper provides a detailed description of P2S (Process-to-Services), a computer-aided methodology to enable the identification of services that compose a collaborative business process based on metrics defined to setup service granularity, cohesion, coupling, and reuse.
Abstract: Service identification is one of the main phases in the design of a service-oriented application. The way in which services are identified may influence the effectiveness of the SOA architecture. More specifically, the granularity of the services is very important in reaching flexibility and reusing them. Such properties are crucial in interorganizational interactions based on collaborative business processes. In fact, collaboration is facilitated by ensuring a homogeneous description of services at the right level of granularity. In this paper, we provide a detailed description of P2S (Process-to-Services), a computer-aided methodology to enable the identification of services that compose a collaborative business process. The methodology is based on metrics defined to setup service granularity, cohesion, coupling, and reuse. A prototype tool based on the methodology is also described with reference to a real case scenario.

TL;DR: In this article, the authors present a service creation environment and a service execution environment, which can be implemented within a single console or separately implemented within different consoles, or the environment can be embodied within a stand-alone computer.
Abstract: In a wireless communication system (100, 200), at least one service building block (605-610 and 622) is used in a service creation environment (301) to create logic program rules (303) that include identification of an authorized service execution environment. The logic program rules, which may require further configuration, are provided to a service execution environment (302) having an identification that matches the identification of the authorized service execution environment. Configurable software modules within the service execution environment are executed in accordance with the logic program rules when at least one predetermined stimulus is detected, thereby providing the service within the system. The service creation environment and the service execution environment may be implemented within a single console or separately implemented within different consoles, or the service creation environment can be embodied within a stand-alone computer (201). In this manner, rapid service creation is provided.

TL;DR: This paper presents a blueprint for a service-oriented identity management architecture featuring interoperability by applying existing standards and has been tested and evaluated in an implementation case study.
Abstract: Service-oriented architecture (SOA) will form the basis of future information systems. Web services are a promising way to implement SOA enabling the loose coupling of functionality at service interfaces. The focus in SOA changes from traditional software systems to reusable, business-relevant services. Considering the cross-cutting concern of identity management (IdM), it is still an open issue how to construct an SOA-aware IdM architecture enabling "identity as a service" and how to loosely couple the IdM services with SOA's core concern part. In this paper we present a blueprint for a service-oriented identity management architecture featuring interoperability by applying existing standards. Our solution has been tested and evaluated in an implementation case study.

TL;DR: The intelligent network conceptual model is used to introduce an intermediate layer, named service layer, to interface the network customer to a service-independent transport network to deliver emerging services in an integrated way.
Abstract: In the last few years customers are willing to use broadband connections to support concurrent and heterogeneous services. At the same time telecommunication operators would like to use the same transport infrastructure (possibly with minor changes) to deliver these emerging services in an integrated way. To this purpose, enhancements of the existing ASTN architecture are proposed. Specifically the intelligent network conceptual model is used to introduce an intermediate layer, named service layer, to interface the network customer to a service-independent transport network. The service plane has the task of masking the transport-related implementation details from the abstract request of a service by a customer. In addition, the service layer inherently suggests the separation of the telecommunication operators role in two distinct activities: the network provider and the service provider. The proposed service-oriented architecture is described in terms of functional blocks and interfaces and it consists in an open framework subjects to be implemented using whatever technology, both hardware and software. For a proof of concept, a testbed, named SOON (service oriented optical networks) running the newly developed service-oriented software modules has been implemented as an example of direct interaction between customer and optical network for a dynamic service request. The validation of the architecture is done by demonstrating a working service, namely a virtual private network (VPN) service.

TL;DR: This paper advocates an objective experience-based approach for service provider selection, in which consumers record their experiences with service providers rather than the overall, subjective ratings for a provider.
Abstract: Selecting the right parties to interact with is a fundamental problem in open and dynamic environments. The problem is exemplified when the number of interacting parties is high and the parties' reasons for selecting others vary. We examine the problem of service selection in an e-commerce setting where consumer agents cooperate to identify service providers that would satisfy their service needs the most. Previous approaches to service selection are based on capturing and exchanging the ratings of consumers to providers. Contrary to previous, rating-based service selection, this paper advocates an objective experience-based approach for service provider selection, in which consumers record their experiences with service providers rather than the overall, subjective ratings for a provider. A consumer's experience with a service provider is represented using an ontology that can capture subtle details including the context in which the service was requested. When a service consumer decides to share her experiences with a second service consumer, the receiving consumer evaluates the experience using its own context and evaluation criteria. By sharing experiences rather than ratings, the service consumers can model service providers more accurately and thus can select the service providers for their needs more correctly.
