This paper proposes Ubiquitous Context Aware Recommender Systems for Ubiquitous Learning (UbiCARsUL) As the new learning paradigm, known as ubiquitous learning or U-learning, which is supported by the ubiquitous computing technologies and Context aware recommender systems. Which enables students to access learning materials by utilizing 2D bar code or QR Code in Thai Herb campus? Students can learn...
This article discusses the trend toward ad-supported ubiquitous computing as well as the problems advertisers face and how ubiquitous computing can solve them. It mentions that advertising will be the next major application for ubiquitous computing. Ads will support ubiquitous computing, and ubiquitous computing will support advertisers with ad targeting, ad feedback, customer awareness, and privacy.
In any systems or environments within a ubiquitous computing context that promotes the concept of users interaction or inter-organization communication, more specifically data sharing and takes users within such context as relevant contextual information, there is the potential for interactions between systems to occur that may affect the security of the overall system. We present a scenario that...
The paper proposed and developed a core component an “information agent shell,” IAS, to apply in the general Web systems and investigate the related problems with the extension in a wide variety of application areas. The shell contains the four main components: OntoCrawler, OntoExtractor, OntoClassifier, and OntoRecommender, which are responsible for information searching, information extracting,...
Service process usually needs to be tailored for reuse because of change of context. In this paper, we present a mining approach to mining process change sequences based on different context using partial derivatives of the factors affecting the change context, thus finding the best feasible sequence.
Human activity is highly influenced by the context and environment of the user. Presence of other users in the vicinity can also influence the context of use and thus activity. In ubiquitous computing environments, people are surrounded by numerous computing devices helping them to carry out various tasks. However, users seek precise and fine-grained information that is not provided by the computing...
In recent years, advances in hardware technology have facilitated the ability to collect data continuously. Simple transactions of everyday life such as using a credit card, a phone or browsing the Web lead to automated data storage. In this paper, we are focuses on finding frequent itemsets over ubiquitous data streams. The proposed method shows that false negative oriented approach that allows a...
This paper presents a new context awareness service decision method based on fuzzy set theory and the knowledge discovery technique in rough set theory. The established system model in the paper provides users with a service list ranking according to possibilities of each service that users may need. Moreover, accuracy of decision rules can conclude from the system model.
Detecting and understanding Web search intention have considerably gained in interest during the last years. This is challenging in mobile environments due to the impact of ubiquity on the mining process: changing user's context influences the information needs, resource constraints affect the process execution. Moreover, in mobile devices it is possible to find situations where the analysis of user's...
Understanding linguistic culture is indispensable to learn foreign language. In Japanese language learning, polite expressions are related to Japanese culture closely, we proposed to design a context-awareness ubiquitous learning environment for Japanese polite expressions learning. In this paper we will address how we designed this environment for supporting the collaborative learning according to...
Cloud computing extends an enterprise ability to meet the computing demands of its everyday operations, while offering flexibility, mobility and scalability. However, the reason that chief information officers (CIOs) and their colleagues hesitate to let their business workloads to move from private cloud into public cloud is security. This work tries to offer a line of defense by applying mobile agents...
As pervasive applications become prevalent in our day-to-day lives, the interactions of service provision and consumption between unknown and strange users are commonplace. Trust and reputation systems play a vital role in such application scenarios. One of the problems is that selfish users are reluctant to render the truthful recommendation without incentive. Even if there are incentives, self-interested...
The indisputable dominance of mobile and pervasive computing devices and their typical characteristics require services offered to be rethought and sometimes redesigned in order to better assist users. Considering the importance of data mining services to provide intelligence locally on devices on these environments, we propose a data mining service that adapts the embedded data mining algorithm according...
Future networks are envisioned to satisfy the user needs and improve their quality of experience. This requires the networks to support context-aware information, where context of the user, session, network and environment will greatly influence the way the session is delivered: new approaches are required to deal with the overall context information and network reaction to constantly context changes...
Context-awareness and adaptation are key issues in mobile and ubiquitous computing. Applications on mobile devices use context information to adapt themselves to changing environments. User profiles play an important role in these systems as they serve as an individualization filter in a wide range of possible context adaptation parameters. In this paper we propose a modeling approach for the evolution...
Recent developments of information technologies are leading the advent of mobile device oriented context-aware applications, which means using context to realize some novel applications on mobile devices. The context-aware application needs a framework for context information management. In this paper, we propose a mobile device oriented framework for context information management to solve the problems...
The existing synchronization solutions of mobile database are not independent from the database server because they use database dependent information such as metadata or use specific functions of database server such as trigger and time stamp. These constraints are critical weak point in ubiquitous environment because various applications are running in various devices and servers in ubiquitous environment...
For ubiquitous computing environments, an important assumption is that all the components in any specific environment are connected with each other. With this assumption, we can share various kinds of content across mobile terminals. This paper introduces an effective scheme to manage multimedia sharing based on specially designed profiles and a virtual community. A virtual community is defined as...
Visible Past proposes a new class of interdisciplinary learning, documenting, knowledge production, and discovery experiences that are anchored in space and time indicators. The project is supported by a ubiquitous computing platform with Wiki, implicit social networking, and location aware capabilities. The environment can be used as an integrated framework for enhancing learning and research in...
The technologies of mobile communications and ubiquitous computing pervade our society, and wireless networks sense the movement of people and vehicles, generating large volumes of mobility data: location data from mobile phones, GPS tracks from mobile devices receiving geo-positions from satellites, etc. The GeoPKDD project, a large European research initiative, has studied how to discover useful...
