Cloud computing has been evolved as a key computing platform for sharing resources and services. People should have a relatively convenient environment and life for handling home-appliances. This study designs and develops a Web 2.0 Service Platform (WSP) for DPWS-based Home-appliances in the Cloud environment, which is composed of mobile users, home appliances and the cloud environment. WSP automatically...
Mobile commerce (M-commerce) is an attractive research area due to its relative novelty, rapid growth, and great potential in business applications. Unfortunately, there are a number of constraints effecting both performance and usability of mobile devices and network bandwidth. In addition, existing M-commerce applications are lack of fully automated business processes and still require significant...
The following topics are dealt with: Web usage mining; Web intelligence; Web information retrieval; Web information extraction; Web information classification; Web content mining; semantic Web and ontologies; XML and semistructured data; Web services; Web interfaces; multi-agent systems; mobile computing; intelligent networked systems; information security; e-learning; e-government; e-commerce and...
As Web services and the semantic Web become more important, enabling technologies such as Web service ontologies will grow larger. The ability of mobile devices, such as cell phones and PDAs, to download and reason across them will be severely limited. Given that an agent on a mobile device only needs a subset of what is described in a Web service ontology, an ontology sub-graph can be created. In...
The following topics were dealt with: dynamic and declarative business processes; middleware for Web services; advances in quality of service management; mobile technology in enterprise computing systems; security and privacy in enterprise computing; service-oriented business networks and ecosystems; and vocabularies, ontologies and rules for the enterprise.
The key objective of OPUCE system is to enable the participation of end-users in the management of their own services, by providing them with innovative tools which allow an easy creation and delivery of personalized communication and information services. This paper describes the OPUCE service and component repository, which extends the OMA OSPE service model storage approach XDM. By integrating...
A new generation of mobile device users is coming of age in the next decade. These users can explore the mobile internet with its new features, services, and applications. Recently, an application platform like the Google's Android mobile platform has revolutionized open applications development for the mobile platform. As increasing number of companies expose their services as web services, enabling...
This paper presents "ConServ", a Web service for context management. ConServ allows smart spaces to access user's context data according to user-defined policies. This Web service addresses the sharing and management of context data between smart spaces and as a result facilitates the creation of new smart spaces and the enhancement of old ones. Data related to a user's location, calendar,...
Advancements in wireless technologies and mobile networks are increasing the demands for novel mobile services beyond voice and text-messaging applications. However, discovering such services from any device is still a major challenge. This can be considered from two perspectives: the variety of mobile devices available and the lack of service descriptions. In order to address these issues, in this...
We describe a framework for wireless sensor network (WSN) based mobile mashup applications. The framework consists of four functional components: WSN, mobile gateway, context management platform, and mashup server. The WSN deployed in the application domain senses the physical phenomena and the human-environment interaction and expresses them in sensor readings. The mobile phone is used as the gateway...
The following topics are dealt with: Web services architecture; rule-based Web services system; learning object selection; Web service composition specification; UML-S; grid services; Web service failure recovery; collaborative tagging system; user preferences; mutation testing; text compression; agent-based dynamic semantic Web service selection; ontology recovery; semantic match algorithm; mobile...
Nowadays, there are numerous web services with specific capabilities within various networks, which can be used by mobile users. How to find a suitable service is a challenging task for a user and matchmaking is the key for the service discovery. In this paper we propose a matching algorithm measuring the similarity of the request with each of the advertised services based on OWL-S. As a description...
One of the goals of mobile and ubiquitous computing is to enable ad-hoc interactions between different kinds of entities to help end-users perform different kinds of tasks. These entities, which include devices and services, may either be mobile or situated in the surrounding physical environment. However, these interactions require the use of rich semantic models describing the capabilities of the...
Without a robust mechanism for integration of the various environments and their related ontologies it's difficult to realize a ubiquitous environment in which mobile users and devices can seamlessly interact and acquire services. Therefore, if a robust and semantic mapping among the ontologies of different environments can be built then they can be integrated with each other. This paper proposes...
With advances in automatic position sensing and wireless connectivity, location-based services (LBS) are rapidly developing, particularly in fields of geographic, tourism and logistic information systems. Currently, Web service has been viewed as one of most significant innovations in business industry, and designed on demand to provide spatial related information for LBS consumption. However, the...
Context-aware applications can satisfy users' information needs without consuming too much time in discovering information adaptive to users. In this paper, we propose a personalized information system to provide more user-oriented information considering context information such as a personal profile with preferences, location, traffic condition, weather, time, event, and so on. Our system architecture...
With the recent advances in Internet and mobile technologies and infrastructures, there are increasing demands for ubiquitous access to tourist information systems for service coordination and integration. However, disparate tourist information and service resources such as airlines, hotels, tour operators, etc., make it difficult for tourist to use them effectively when planning their trips and/or...
In this paper, we present the implementation, evaluation, and application of our OWL-S service composition planner OWLS-XPlan. Medical services described in OWL-S 1.1 and ontologies are converted to initial state and goal descriptions in PDDL 2.1, which are then used by the fast heuristic FF planner XPlan for generating an execution complete composition plan. Results of experimental evaluation of...
