To recommend a travel plan for elderly people, we have to consider more constraints related to ability and health. Existing Web services of travel do not consider these constraints. In order to enhance the quality of live (QoL) of elderly people, we propose a pattern Web service, which takes into account these constraints. Our goal consist to use advantage of semantic Web in order to consider fully...
The methods for document or web page search can not be adapted well for the efficient service search for the lacking of service descriptions. Importing new information related to services to help service search is an urgent task, which can support the development of SOA (service oriented architecture). One of the popularly used information is service context which describes service-related usages...
In order to process service failure quickly, a new failure recovery for service supporting context persistence named G-FRF is given, which is based on the existing failure recovery frameworks for Web Services. Failure recovery requirements of manager job services in grid computing are taken into account in the framework. during normal execution, service state is monitored and context is saved. When...
Assessment process in one of the most important issues in the learning process and in many cases it is the process that define the sequence of the instruction because it measures the performance of the student in the educational process. In last decades the inclusion of TICs in teaching-learning process has facilitated to address the diversity of students and teachers features. Learning technologies...
Ultimate goal of ubiquitous computing is to move computers away from the user's focus, by embedding them into the environment. The user will be surrounded by smart and internet powered devices. In this work we describe our research about the Smart Home system. Our solution contains all sorts of smart entities necessary at home. For the interaction with the user we defined two outputs: Smart Wall and...
Additively to the emergence of wireless networking, high technology and reliability of mobile devices have enabled the widespread use of mobile computing. Currently, this last is in vogue and booming. Today, the combination of mobile networks with Web Services called "Mobile Web Service", opening a promising horizon for the economy. They offer (Mobile Web Service) new personalized services...
As current trends show, the Semantic Web is the future interaction environment used in data exchange and integration among homogenous applications. This trend raises new challenges in security models used for access control, and the only acceptable model is to take into account the semantic relations of the interacting entities. In this article we present the access control module used by the Mobile...
Context recovery can improve the efficiency of web service replacement. In order to solve the problem that when to do service context migration, this paper proposes an algorithm of context migration timing judgment which is based on the initial state, real time availability and availability changes of web service. According to this algorithm, we can determine whether to do service context migration...
An extension of the HTN-DL web service model is presented, including rules for web service behavior and compliance validation against customer requests. The intention is to overcome the limitations of HTN-DL and OWL-S in covering business constraints in service selection and also the limitation of preconditions. The proposed approach validates a web service obtained through HTN-DL planning, for compliance...
With the advance and pervasion of mobile devices and fast growth of high speed Internet connections, our life is inevitable to be changed. These devices are combined with sensors such as Radio Frequency Identification (RFID) operating on wireless infrastructure to form a wireless sensor networks (WSN) which could facilitate our life in many ways. We would expect a shopping experience in which customers...
Automated services composition is an active research area nowadays. The application of this technology to specific domains, as well as the use of basic Telecommunications services such as call or SMS, offers new challenges. This paper presents the main components of an architecture for automated composition for Environmental Management. The proposed architecture uses Natural Language processing and...
Despite 20 years of research, ubiquitous systems have yet to become truly ubiquitous. A key challenge is the design for volatility and evolution experienced when those systems are deployed in more than one environment as well as for a substantial time period. The work presented here describes a proposed federated System of Systems (SoS) engineering approach for creating ubiquitous systems based on...
In recent years, Service Oriented Architecture (SOA) has been increasingly adopted to develop applications in the context of Internet. To develop reliable SOA-based applications, an important issue is how to ensure the quality of Web services. In this paper, we propose a dynamic random testing (DRT) technique for Web services which is an improvement of the widely practiced random testing. We examine...
Services computing is becoming one of the most widely adopted software paradigms in today's network computing environment. Due to the rapid development of web services technology, there are growing number of web services applications distributed over the Internet. While the identification of web services that best meet the users' needs and preferences remains an unsolved problem, requirements, social...
The efficient cooperation of Web services is essential to applications of a Virtual Organization (VO). However, lots of challenges result from the diversity of services and the variability of business requirements. A novel approach to service cooperation based on Agile Services is proposed. The model of Agile Service is realized based on Tree Syntax. Aiming at mismatches of services existing in the...
In a largely scalable Web services-based environment, context-awareness is concerned with reasoning about the surrounding well-defined context and adapting the interpreted services accordingly (almost) on the server-side, and finally distributing the services to clients in a reliable way through trustworthy network protocols. Most of Web services-based context-aware applications are either partially...
Nowadays, location-based services are widely utilized, including identifying user locations, offering traffic status, providing point of interest (POI) information, and guiding routes. At present, users always make use of location-based services via smart phones, and can obtain information anywhere and anytime. However, users easily receive information in which they were not interested. This kind...
Accounting for quality correlations among web services when performing service composition is essential to obtain more accurate quality estimations of service combinations, thus providing users with better composite solutions. Yet, most current composition approaches fail to address such correlations by assuming independence between services regarding their quality values. In response, this paper...
Information diffusion has been studied between and within biosphere, microblogs, social networks, citation networks and other domains, where the network structure is present. These studies have turned to be useful for acquiring intrinsic knowledge for strategic decision making in related areas, for example, planning online campaigns in case of microblogs and blogosphere. In the context of data-centric...
With the development of service-oriented computing environments, QoS-aware service selection has been a more and more important research issue. In service composition environments, QoS attributes of atomic services are always aggregated for computing the QoS of the composite services, which has been reported in many previous studies. However, there are situations that some QoS attributes cannot be...
