Service matchmaking is a basic feature of service-oriented architecture (SOA). In this paper, a semantic-based flexible service matchmaking approach is presented to efficiently identifying functionality-compatible services. This approach utilizes SAW-OWL-S to specify the service advertisements and service discovery requests. The functionality-compatibility of a service to a request is defined on their...
This article analyzes system integration technology, database technology, SOA architecture and intelligent building system requirements and proposes an SOA based intelligent building management system(IBMS). Then BPEL4WS is adopted to arrange the system services. It enable the service to change from fine grained to coarse grained and form business related to system, realizeing the detailed functions...
The problem of designing of the services catalog with the purpose of increasing the efficiency of the management of a large corporation is considered. A centralized and decentralized model for the formation of a service catalog is considered. The problem of optimal allocation of resources for cataloging is set. Approaches to solving this problem using heuristic methods are considered. The problem...
The rapid growth in market demands for high-quality, state-of-the-art, and reliable communication services increases the amount of session-control signaling, which is mainly based on the Session Initiation Protocol (SIP). Many research activities dealing with the Quality of Service (QoS) have been focused on media-related service components, whereas signaling-related service components have received...
Customer demand for electricity supply is vastly increasing due to urbanization and changing needs. Thus electrical utilities need to accurately determine load profiles for different sectors of the supply area, so that new customers can be seamlessly added. To obtain such information a customer connectivity model needs to be developed and implemented such that historical customer data from various...
Recently, flexible networks contain various services designed and implemented by different vendors to accomplish specific tasks. Trust to security systems of such services is a significant challenge. In this paper, we propose a framework to assess trust to security systems of web services based on security policy specifications and security mechanisms running on flexible networks. The framework may...
Methods for long-distance time and frequency transfer over optical fibres have demonstrated excellent performances and are evolving rapidly. CLONETS is a new European Union-funded coordination and support action intended to accelerate the transfer of these technologies to industry and to strengthen the coordination between research infrastructures and research and education network providers, in order...
Integrated environmental modelling (IEM) couples interdependent environmental models and data together to solve complex environmental problems. There are two major modelling frameworks for IEM: component based framework, and service oriented framework. This paper suggests to take the best of both to couple modelling components and services together. The result is a hybrid method to leverage Open Modelling...
This paper defined a unified architecture of IoT system, on which IoT node model, virtual things, the basic service of things and overall hierarchical model of services had been described. IoT nodes must be connected directly to Internet and provide basic services of things in this architecture, and started from the base services which were compatible with Internet applications system of SOA, built...
Researches on service systems have been conducted for more than a decade, resulting in concepts and knowledge of the service system. These lead to the intention of the organizations to create a service system that is able to provide service value. As the service sector grows, the organizations are required to be able to develop such a service system that gives benefits to the organizations and has...
Cloud computing theoretically offers its customers unlimited cloud resources. However, the scalability of software services is often limited by their underlying architecture. In contrast to current scalability analysis approaches, we make work parameters, quality thresholds, as well as the resource space explicit in a conceptually consistent set of equations. We propose two scalability metric functions...
Due to the fierce competition globally, standardized product and service are difficult to meet customized demand. Thus, providing personalized products and customized service have become more and more popular for the manufacturers in order to establish their competitive advantage and win customers. As an effective marketing tool, basic warranty has been sold with the products for many years, and in...

One key goal of Vehicular Ad-hoc Networks (VANETs) is to provide sufficient Quality-of-Service (QoS) for real-time safety applications. These applications facilitate wireless broadcast warning messages between neighboring vehicles to inform drivers on time about dangerous situations like accidents. The IEEE 1609.4 standard in DSRC defines a MAC layer implementation for multichannel operations in VANETs...
In the past few years, social tags and tagging systems have gained large momentum for service categorizing and indexing content on the Web. Tags are used freely, which leads a random correspondence between the tags and the services, which affects the performance of the tag in the search and applications. We propose a novel scheme for tag predicting based on graph, aiming to automatically sort the...

A key issue in big service era is how to optimallyconfigure and operate existing service resources to serve variousrequirements of customers, i.e., how to reuse available servicecomponents to develop new service systems to fulfill massiveindividualized requirements effectively and efficiently. In termsof this challenge, in this paper we present a new paradigmfor software service engineering called...
Given that the number of ready-to-use web services is steadily growing, services will provide solutions to a vast range of business problems in the future. And thanks to findings in end-user development research, popular service integration platforms such as IFTTT and Zapier emerged, making process automation as easy as never before. This progress will affect software engineering increasingly: as...
This paper deals with home batteries and their economic viability under a service in which a prosumer possessing a roof-top PV system can purchase a battery system with the special price from an electricity provider and obtains annual fees for assumed time period. It is done in exchange for sharing some part of battery capacity with the entity. The aim of this study is to check whether it is economically...
