With the giddy growth of the amount of the information data through constant interaction and sharing in daily life, the mobile Internet has shifted from the lack of information to information overload. How to satisfy readers' individual needs from the disorder and mixture data has become an urgent problem to be solved. This paper combines the context information into the recommended process, and constructs...
The development of context-aware applications is a complex process that involves context management. A context life cycle implies 4 essential steps: context acquisition, context modeling, context reasoning and context dissemination [1]. In [2], we tackled the issue of context modeling and reasoning by proposing an approach based on Relational Concept Analysis (RCA) and Descriptive Logic (DL), respectively...
Recently, interaction with computer applications in a pervasive environment has increasingly benefited from mobile technologies. These technologies generally attributed to the environments of physical and social properties. Therefore, the adoption of these technologies ensures more flexibility and creates new forms of use. The consideration of the context of use in pervasive interactive applications...
People use reminders to recall tasks to-do. But sophisticated enough tools are unavailable. Context-Awareness in mobile computing is more engaging area in gathering information about the user's current situation and would be ideal to integrate with the reminders to generate context-aware reminder where rich context is used to identify when a reminder should be presented to its recipient. Here we have...
Adapting application to diverse/dynamic domains is required to enlarge pervasive computing use, to satisfy people demand in terms of continuity of services. In addition, the proliferation of smart devices, ubiquitous services motivate the need for a quick development of applications that support people in dynamic domains. Inappropriately, this quick development is often associated a discard of domain...
Urban search and rescue (USAR) missions can benefit a great deal from teams of mobile robots endowed with advanced perception capabilities. To effectively collaborate with humans, these robots should have situation awareness about their robotic and human teammates, for intuitive decision making. Moreover, robots should be able to contextually share information so that humans can benefit from augmented...
In context aware settings, if one or more services are unavailable, it may be useful to look for a set of services whose combined effect would be functionally equivalent to a given request. We show that the notion of functional equivalence is quite useful in some real world scenarios. In this paper, we suggest a method to obtain a composed service whose effect is functionally equivalent to the given...
The current service discovery mechanisms are syntactic methods that often offer poor quality results. By researching this area we are able to identify issues that limit the quality of the result with these traditional service mechanisms. To overcome this issue we use ontologies to enable semantic matchmaking. By reasoning on concepts and relations, our approach can derive matches that syntactically...
Context-awareness plays an important role to offer an intelligence in terms of provision of user-centric features in Internet of Things (IoT). Web of Objects (WoO) has been introduced to support a framework to simplify application deployment, maintenance and operation of IoT service infrastructure by classifying and integrating objects on the World Wide Web. The semantic ontology is applied on a WoO...
The interaction between elderly's body states and their surrounding environment is important in many conditions. Biological data and activity data in elderly's daily life using wearable body sensor can be monitored and then can be adjusted with environment to gain the comfort condition. Seamless integration home care which is embedded with pervasive devices and awaring of the context can help residents...
Service Oriented Computing provides us with an opportunity to build distributed applications by invoking and selecting suitable services. In this paper we attempt to select context aware service and apply this to medical emergency scenario. This paper proposes an approach to select web services based on user context. Experimental results demonstrate that proposed method provides reliable solution...
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...
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...
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...
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...
This paper introduces a new context modeling approach for the business process management field. The proposed approach aims at identifying and formalizing the contextual knowledge relevant to business processes in order to be able to adapt business processes according to the context. This approach has the particularity to be generic and extensible, it can be integrated with many business process modeling...
There is currently lot of work in Ambient Intelligence particularly in context awareness. Context awareness enables service discovery and adaptation of computing devices for Ambient Intelligence application. In the same time, there is a common agreement of the fact that context aware systems should be responsive to Multi agents, assisting a large number of people, covering a large number of devices,...
Web service compositions run in changing environment where different context events can arise to affect the execution of services. In order not to make service execution affected by context events, context-aware service composition becomes one of the major research trends. Service providers can develop context-aware services which can adapt their behaviors dynamically to execution contexts. However,...
The Internet of Things (IoT) has given rise to new types of data, emerging for instance from the collection of sensor data and the control of actuators. The explosion of devices that have automated and perhaps improved the lives of all of us has generated a huge mass of information that will continue to grow exponentially. For this reason the need to store, manage, and treat the ever increasing amounts...
With rapid development of IOT (Internet of Things), the computing mode of the 21st century is undergoing profound reform. IOT's final goal is fusing the information space composed of computers with the physical space in which the people are working and living in. By this fusion, people can get information service transparently according to their personal needs whenever and wherever they are. However,...
