Availability and reliability of Web services are important issues for developing many electronic business applications. Unfortunately, it is hard to guarantee the availability of a service given that the number of its requests might be potentially huge. In this paper, we propose a novel approach for robust Web service provisioning based on mobile agent and resource discovery technologies. With ...

In this paper we show how UML 2.0 sequence diagrams can be used for the design of Web service choreographies with time constraints and how these sequence diagrams can be extended with frames for the description of Web service choreographies. We then show how the diagrams can be translated into WS-CDL documents. This translation is of interest, since non-XML experts can find it difficult to impl...

We present partial information extraction approach to lightweight integration on the Web. Our approach allows us to extract dynamic contents created by scripts as well as static HTML contents. Our approach has three application areas: automatic generation of Web services from Web applications, automatic integration of Web applications with Web services on desktop computers, and automatic integr...

In this paper, we introduce a mobile services environment, namely SMOP, in which semantic web based service capability matching and locationaware information gathering are both used to develop mobile applications. Domain independency and support on semantic matching in mobile service capabilities are the innovative features of the proposed environment. Built-in semantic matching engine of the e...

This paper describes the design of our service-oriented architecture to support mobile multiple object tracking augmented reality applications applied to education and learning scenarios. The architecture is composed of a mobile multiple object tracking augmented reality client, a web service framework, and dynamic content providers. Tracking of multiple real objects and retrieval of associated...

In mobile agents systems, classical techniques for system optimization are not applicable due to continuous changes of the execution contexts. MAWeS (MetaPL/HeSSE Autonomic Web Services) is a framework whose aim is to support the development of self-optimizing autonomic systems for Web service architectures. In this paper we apply the autonomic approach to the reconfiguration of agent-based app...

Problem statement: Language Lab plays crucial role in learning foreign language. With its capability to create environment of connecting students with students, connecting student with teacher and giving the impactful learning resources, some of institution are dare to invest of expensive system. Hence, some of them keep searching for more efficient way to learning language. In this study, base...

Performing complex tasks over the Web has become an integral part of our everyday life. The advent of mobile services will add to the broad range of existing services offered on the Web and provide additional features like location-based information. To take full advantage of complex service offerings, even on limited client devices, and to handle the growing variety of applications, powerful c...

Providing an easy-to-use service framework for mobile context-aware applications is a real challenge. This paper describes how context information in mobile 3G networks can be unlocked via web services. We describe a service framework that builds on top of these web services, to enable the rapid development of applications that are aware of the context of the end-user, are able to reason with c...

In present times, quite a large number of network applications have been implemented as Web services to take advantage of World Wide Web, the most popular and common platform in the Internet. Although most modern mobile devices are able to connect to the Internet and hence capable of accessing Web services as stationary clients do, they often suffer from performance degradation because of the u...
