Web services bring more conveniences for users and developers. However, it makes user face the problem of service information explosion. The personalized service recommendation solves the problem. This paper proposes a method to predicting the system reliability which bases on user context information in mobile computing environment. The method construct user behavior model by formatting user location...
This paper proposes a framework for the collaborative consumption and creation of knowledge where its quality is measured as well as the authors' reputation. A specific implementation for smartphones for the collaborative creation of quality questions and answers is presented.
The discovery process has become an important task in the web service life cycle as the number of Mobile Web Services (MWS) has increased nowadays. However, discovering relevant MWS that can match a service request with the service offered has remained a major hindrance. The challenges are concerning the web service discovery with the limitation of mobile devices related to performance. On the other...
The use of mobile devices as data service providers is on the rise. Mobile devices feature a large set of distinct characteristics that qualify them to be the most convenient computing platform for online services, both as consumers and providers. Mobile devices can take advantage of their mobility to provide location-based services and their association to a specific user to customize service offerings...
Mobile devices with their various form factors have become the most convenient and pervasive computing platform, whether to carry out everyday business or to get online. Mobile users tend to adopt the fast food trend even in consuming online mobile services and functionalities. The Web service approach promises great flexibility in offering software functionality over the network, while maintaining...
Mobile Applications are rapidly emerging as a convenient medium for using a variety of services. In ubiquitous environment, the challenge relies on developing applications that sense and react to environmental changes to provide a value-added user experience. This context awareness property improves application usability. Context information can be related to the environment, user but also to the...
This research summary outlines results achieved by Hamburg University during its participation in the EU NoE “S-Cube” focusing on process instance migration. It includes corresponding results in the context of dynamic and mobile environments (as, e.g., provided by mobile web services, NFC-aware process execution, future-context-aware applications or interactive workflows) and focuses on the management...
Rich context available creates varied applications on mobile device and makes end-user possible to customize personalized context-aware application. Meanwhile, problems arise that how to realize the service composition and present the service easy for end-user programming. In this paper, we refer to the notion of service component, design and implement a Context-Source Service Composition Prototype...
The creating of reusable mobile solutions is influenced by many factors. The platforms are arbitrary, the target audience can be new to mobile software, and the devices are not always online and restricted in their computational capabilities. This paper presents an archetype pattern- and REST-driven approach for building customizable, flexible, and efficient mobile business applications. Furthermore,...
The “Web of Things” vision promotes the integration of smart devices into web, using web technologies and protocols as underlying interaction mechanisms with smart devices. Technically many phones include various sensors and provide a large-scale sensing platform. To make this functionality available to a large number of (web) developers our research aims at easing the creation of applications that...
With the recent popularization of smart phones, context sharing systems in mobile environment attract attention of people. Mobile context sharing systems can share more information than web-based social network services because they have various sensors. For sharing high-level contexts such as activity and emotion, a user had to manually annotate them in previous works. This paper proposes a mobile...
Users often visit many stores while they compare merchandise in order to purchase the merchandise or merchandise related to it. Given a service providing information such as location of these stores, they can reduce their time and effort spent by wandering around them because they can go straight to these stores. And they can obtain new purchase opportunities because they can know what kinds of related...
In order to make mobile devices get Web Services continuity and stability, we propose a method called lazy strategy for efficient utilizing Web Services, which used as computing strategy when we encounter avalanche of expressions in runtime. Both the conception and technology as we known are just like an introduction or elimination approach that it solves the space explosion problem by type checking...
The increasing processing power, storage and support of multiple network interfaces are promising the mobile devices to host services and participate in service discovery network. A few efforts have been taken to facilitate provisioning mobile Web services. However they have not addressed the issue about how to host heavy-duty services on mobile devices with limited computing resources in terms of...
For the last decade, the area of e-business and e-service has expanded rapidly. Service Oriented Architecture (SOA) is introduced to create and execute a business process on the Web. In order to create and execute the business process, relevant web services need to be composed or reconfigured based on the business process logic. Traditionally, web services composition and reconfiguration are optimized...
Web services provide a successful way to communicate distributed applications, in a platform- independent and loosely coupled manner. Even though there are examples of good practice for the design, development and management of Web services, there are scopes in which Web service adaptation is required, such as context, device and customer adaptation. Current proposals usually focus on client-side...
This work proposes an architecture called SMBots that allows web service providers to make their services available through SMS targeting low-end mobile phone users. The main idea consists of allowing developers to plug their web services in an SMS infrastructure in order to make them available on the fly to mobile phone users. Using OSGi as the framework to handle those pluggable applications, SMBots...
This paper describes a middleware intended to support the development of mashup applications in mobile and ubiquitous learning environments. It is based on a framework that integrates different contextual information (e.g. geographic location, profile, history) and services (from e-learning platforms or other learning tools). The integration of the services into the middleware is carried out through...
In the near future, the trend of user-generated content and services currently observable in the Internet domain will also affect the mobile environment: mobile users will become able to easily create content and small services while on the move and offer them to social communities. Mobile users will no longer be pure consumers, they will also become producers and providers of mobile content and services...
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...
