TL;DR: In this paper, the social networking service is linked with the other services and the other service is incorporated as a part of the social network service and provided for the user, and it is only required for a user utilizing the social networks service to register a difference from already registered information.
Abstract: PROBLEM TO BE SOLVED: To provide a social networking service system incorporating other services depending on a user. SOLUTION: The social networking service is linked with the other services and the other service is incorporated as a part of the social networking service and provided for the user. Then, it is only required for the user utilizing the social networking service to register a difference from already registered information. Thus, the original contents of the other service are inserted and displayed in the area 340 of the screen 200 of the social networking service, the other service is provided depending on the user, and the user unitarily utilizes all the services. This invention is applicable to a server device which provides the social networking service. COPYRIGHT: (C)2008,JPO&INPIT

TL;DR: An intelligent registry with constraint matching capabilities to support composite service discovery and description is presented and a semi-automatic mechanism and a search algorithm are used to construct a composite service template that satisfies the request.
Abstract: With the popularity of the Web services technology, more and more software systems’ functionalities become available by being published and registered as Web services. Registered Web services need to be dynamically combined to form “composite services†when individual “simple services†fail to meet service requestors’ complex service needs. In this article, we propose a semi-automatic approach to composite Web services discovery, description and invocation. We present an intelligent registry with constraint matching capabilities to support composite service discovery and description. It provides a user interface to interactively compose a service request. It then uses a semi-automatic mechanism and a search algorithm to construct a composite service template that satisfies the request. The operations of the template are bound to registered service operations by constraint matching subsequently. The resulting composite service is specified in the Web Services Flow Language. A composite service processor is designed to execute composite services by invoking the component service operations of various service providers.

TL;DR: A framework for Grid service managent is presented that uses the service metadata and/or service performance models to map client requirents to resource capabilities, it uses business value associated with objectives in allocation decisions to arbitrate between competing requests, and it allocates resources based on previously negotiated agreents.
Abstract: In large-scale, distributed systs such as Grids, an agreent between a client and a service provider specifies service level objectives both as expressions of client requirents and as provider assurances. Ideally, these objectives are expressed in a high-level, service- or application-specific manner rather than requiring clients to detail the necessary resources. Resource providers on the other hand, expect low-level, resource specific performance criteria that are uniform across applications and can easily be interpreted and provisioned.This paper presents a framework for Grid service managent that addresses this gap between high-level specification of client performance objectives and existing resource managent infrastructures It identifies three levels of abstraction for resource requirents that a service provider needs to manage, namely: detailed specification of raw resources, virtualization of heterogeneous resources as abstract resources, and performance objectives at an application level. The paper also identifies three key functions for managing service level agreents, namely: translation of resource requirents across abstraction layers, arbitration in allocating resources to client requests, and aggregation and allocation of resources from multiple lower level resource managers. One or more of these key functions may be present at each abstraction layer of a service level manager. Thus, the composition of these functions across resource abstraction layers enables modeling of a wide array of managent scenarios. We present a framework that supports these functions: it uses the service metadata and/or service performance models to map client requirents to resource capabilities, it uses business value associated with objectives in allocation decisions to arbitrate between competing requests, and it allocates resources based on previously negotiated agreents.

TL;DR: An ontology-based approach for representing service processes and checking their compliance is proposed, based on two ontologies: one to represent the service process and the other to store the compliance requirements.
Abstract: Service processes are becoming increasingly essential in modern economies as traditional, production-oriented industries decline. When comparing service processes to standard business processes, a major distinction is that the quality of their result, i.e., the service produced, cannot be measured in advance. Therefore, the compliance of the service process with quality standards plays an important role in convincing the customer that the services rendered will result in the quality specified. However, the check for compliance is still a tedious task. To address this situation, an ontology-based approach for representing service processes and checking their compliance is proposed. It is based on two ontologies: one to represent the service processes and the other to store the compliance requirements. The process representation ontology uses three so-called views to appropriately represent the service processes. The ontology for storing the compliance requirements differentiates syntactic, semantic and pragmatic requirements.

TL;DR: In this article, a computer-implemented method, system and computer program product for end-user service provider selection in a network supporting one or more service providers connected to the network, including prompting an end user for enduser information including a geographic location of the user, determining based on the end user information whether the network provides service in the geographic location, displaying to the enduser a list of service providers available to the user and supported by the network.
Abstract: A computer-implemented method, system and computer program product for end-user service provider selection in a network supporting one or more service providers connected to the network, including prompting an end-user for end-user information including a geographic location of the user; determining based on the end-user information whether the network provides service in the geographic location; displaying to the end-user a list of one or more service providers available to the end-user and supported by the network; providing means for contacting the one or more service providers available to the end-user; receiving service information from a service provider selected by the end-user from the list of the one or more service providers based on the means for contacting the one or more service providers; and providing service via the selected service provider on the network to the end-user based on the received service information.
