Context awareness is one area that can be explored in developing mobile health (mHealth) application. Context refers to items such as user location, time, environment etc. applications can provide better services to the user by taking this information into consideration. One of the major challenges in developing context aware mHealth application is to store and process raw context data. This paper...
Context aware mobile applications are special types of context aware network systems that process gathered data from environment with context cycle functionalities and special infrastructure to obtain context information. Here, modelling and reasoning are most important functionalities and middleware is one of the common infrastructure to implement these functionalities. Essentially, techniques that...
In this paper, a novel user interest expansion approach for generating recommendations is proposed. The approach utilizes interest of user as well as semantic relatedness between the items along with context to generate recommendations. Ontologies are used to represent domain knowledge. Spreading activation technique uses the relatedness between concepts of user interest in domain ontology to expand...
As applications deployed in a smart space share the same physical environment, they may interfere (or even conflict) with one another. To guarantee the performance and user experience of the entire smart space, mechanisms for handling such interferes (or conflicts) have to be introduced. We believe that conflicts among multiple applications are caused by their different requirements and impacts on...
Smart city is rapidly gaining attention, and more than 400 sites are recognized all over the world, as of the year 2012. Smart city is regarded as an urban area where its social/public infrastructure is efficiently managed using the advanced technology such as ICT, environmental science. The original goal was to form a technology basis for low carbon society or efficient community in energy usage,...
Health promotion related products and services have grown rapidly in recent years, many devices and services were developed for this endeavor. Consequently, there is a need to represent fragmented functions into a general description and comparable shape in order to provide context-based matching and ranking, which is a substance of the whole services. A service discovery was introduced as a mechanism...
Mobile devices like smartphones and tablet computers made it possible to access educational offers spatially and temporally unbounded. However, learners have different prior knowledge and preferences, and are in different situations. Contextual information can be used to adapt educational offers to the learners' individual needs and characteristics. When it comes to the detection of such information...
Context awareness is one of the major research areas of pervasive computing. Several proposals for the design of context aware applications rely on a closed feedback loop that performs four phases. Monitoring and collecting context (phase 1), analyzing the collected context to detect changes (phase 2), deciding adaptation actions related to the changes (phase 3) and performing and executing the corresponding...
With the growing number of web service availablein web, selecting web service that satisfies the users need isbecome more difficulties. So to deal with the problem, numerousapproaches are proposed. Some approaches are interested tointegrate the Quality of Service (QoS) to select the suitableservice. The QoS plays an important role in the discovery andselection process of web services within many similar...
Context aware services provide functionalities which are personalized for their users' current situations. A main concern of context-aware services is a substantial consumption of resources while preserving a minimal level of accuracy. There is a tradeoff between efficiency and accuracy on context acquisition. Hence, we propose a cloud-based Context Acquisition Platform to provide a high-level of...
The quest to transform the television viewing experience into a digital media service is happening thanks to the addition of companion screens to the TV. Multi-device experiences become more intuitive and easier to use federating cooperative devices. They also bring new creative opportunities to schedule and distribute interactive content synchronised with the TV programme through any connected screen...
This paper proposes a new approach to locate software components from large component online open source repositories which encompasses the inherent features of context-aware browsing, ranking and semantic tagging. Tagging of individual components helps making search fast and efficient. We are trying to improvise the results of context aware browsing by ranking them on the basis of Hidden Markov Models...
Recommender systems are a subclass of information filtering system and are widely used in the ecommerce domain [13]. They filter huge amount of data to provide personalized recommendations on services or products to users. Most of the existing approaches to develop a recommender system do not take into account contextual information such as weather, day, time, distance and location to provide recommendations...
An “everyware world” as Adam Greenfield calls it, is a world in which computers are embedded and merged seamlessly everywhere with the environment. Radio frequency and data identification communicates their position and other location information constantly in a vast file network. Everyday objects become searchable if they are part of interconnected World Wide Web. Looking into last three decades,...
Mobile Cloud Computing has been worldwide accepted as a concept that can significantly improve the user experience when accessing mobile services. Mobile applications have become more popular all across the world. By removing the limitations of mobile devices with respect to storage and computing capabilities and providing new integrated levels of security by centralized maintenance of security-critical...
Information and Communication Technologies have changed the way people live and work. Today, in the education field, there are a variety of education systems supporting innovative methods of learning and many universities are investing in creating their own eLearning Environments. Besides, learners' disabilities and learning difficulties still an issue, people can learn easily and deliver better outcomes...
Disasters and emergencies are featured by their unexpected consequences on the human being life. Crisis Management Systems (CMS) handling them require effective collaboration between their services, and need dynamic adaptation at runtime when an execution context change occurs. To manage disasters, several approaches are proposed in the literature where few of them have advocated context-awareness...
In recent years, paratransit is a very important transportation for serving disabilities. Currently, the dispatching center has arranged for driver's tasks which carry passengers. The operators are difficult to efficiently monitor each vehicle's attendance and diving state. The rate of vehicular utilization is low and the problem of service inefficiency appears. Passengers cannot know the arrival...
Wireless Sensor Networks (WSN) are already enabling and enhancing a large number of pervasive computing applications in homes, offices, production facilities, and vehicles, just to name a few. Despite the tremendous evolution achieved in terms of robustness, reliability, maintenance costs, interoperability and other areas, WSN are still difficult to program. This work addresses specifically the case...
With the proliferation of mobile devices and the development of wireless technologies, users can run a wide range of applications on mobile devices. However, the mismatch between applications and mobile devices does not guarantee the application quality. To solve this problem, this paper proposes a context-aware application matching system.
