In the fast evolving social web domain, users have a growing demand for consuming context-aware social experiences and digital content. However, users currently have their social context distributed everywhere, and have limited ownership and control of it. On the other hand, application developers and content providers are having a hard time in reaching out to the right users and creating personalized...
Context prediction approaches forecast future contexts based on known context patterns to adapt e.g., services in advance. In the case of the user's context history not providing suitable context information for the observed context pattern, to the best of our knowledge context prediction algorithms will fail to forecast the appropriate future context. To overcome the gap of missing context information...
Empowered smart objects have become a part of people everyday activities due to the evolution of pervasive computing technologies. In such scenario context awareness plays a fundamental role in enabling adaptation and contextual services. Up to now a lot of efforts have been done in representing context information such as location, time and users identity. At the same time not much attention has...
Social networks represent a sophisticated tool for accessing the preferences and properties of individuals and groups. Thus, they potentially allow up-to-date, richly annotated contextual data to be acquired as a side effect of users' everyday use of services. In this paper, we explore how such “social sensing” could be integrated into pervasive systems. We frame and survey the possible approaches...
Smart objects are gradually integrating into people's everyday life. While many context-aware solutions for pervasive computing environments do not consider users social aspects, we believe smart objects should be social-aware. So Smart aims at filling the gap in social understanding of the user environment, presenting an ontology based context model to support social context representation and automated...
The paper presents the issues on the role of wireless access networks to support the kind of information exchange and interactions involved in the evolving social networks. The author discusses several requirements that the wireless access networks and social networking needs to address such as the communication infrastructure, distributed and informal trusts, environment interactions, body interactions,...
The following topics are dealt with: mobile computing; wireless sensor networks; cloud computing; grid, computing; data center computing; cluster computing; energy-aware applications; virtualization; multicore computing; computer architecture; distributed computing; computer networks; network architecture; CPS security; CPS computing; social networking; Internet of things; WISARN I and embedded system...
The emergence of location-aware mobile social networking applications (SNAs) has gained considerable prominence in ubiquitous computing. However, the weak designs of privacy protection result in more potential risks that users have to face. This paper presents a deep insight into the designs of privacy protection, especially from the perspective of location privacy. Three main potential risks and...
Community structure or clustering is ubiquitous in many evolutionary networks including social networks, biological networks and financial market networks. Detecting and tracking community deviations in evolutionary networks can uncover important and interesting behaviors that are latent if we ignore the dynamic information. In biological networks, for example, a small variation in a gene community...
Recently, SNS, blog and microblog have become very popular. A different form of diversified contents, comparing to traditional static HTML web pages, are so easy to be generated dynamically, and can be provided to users by timeline. These contents are generally processed data streams, and have become an important part of the Internet resources. In this study, we try to integrate these dynamically...
Pervasive Social Computing is a novel collective paradigm, derived from pervasive computing, social media, social networking, social signal processing, etc. This paper reviews Pervasive Social Computing as an integrated computing environment, which promises to augment five facets of human intelligence in physical environment awareness, behavior awareness, community awareness, interaction awareness,...
Nowadays Social Networking phenomenon is gaining a significant momentum. Social Network's users are disclosing a lot of information about their relationships, profiles, preferences and interests. In this paper we describe the achievement of a context Aware platform which leverages a user's Social graph to provide pervasive computing applications based on context awareness. The platform's goal is to...
In the future, pervasive computing technologies will leverage new ubiquitous and intelligent user-oriented services. In this sense, by combining social network analysis, reality mining techniques and context-aware systems, our work provides an architecture and ground steps for understanding and predicting human behavior and preferences within one of the most promising business models of the future:...
Recommender system is mainly based on collaborative filtering algorithms in social network, where it takes folksonomy as basic data structure. Collaborative filtering as a classical method of information retrieval has been also used in helping people to deal with information overload in folksonomies system. When context is taken into account, there might be difficulties when it comes to making recommendations...
One of the most important objects in IT is to enhance the convenience of human-beings. The ubiquitous computing environment, where user can access any networks without time and space restriction, is a result of aggregation of the latest technologies to provide human-beings various capabilities. In this paper, the dynamic community composing model is proposed. The role of this model is to compose a...
The following topics are dealt with: Web intelligence; World Wide Web; Web information retrieval; information filtering; ontology engineering; semantic Web; Web mining; social networks; ubiquitous intelligence; and Web agents.
In an enterprise context, competencies are often dispersed across different teams. A specific need within the enterprise could not be satisfied only because of a lack of awareness about real competencies owned by employees. The aforementioned problem involves two main critical aspects: the difficulty to manage employees' competencies in order to constantly keep them up-to-date and the ability to agilely...
The following topics are dealt with : data security; RFID acceptance; ICT collaboration; 3G mobile networking; social networking; social media education; information security and surveillance; microchip implant; biometrics; RFID implant; enterprise software accountability; digital identity; workplace and citizen surveillance; e-learning; LBS tracking and monitoring; emergency management; smart phone;...
Despite the availability of the sensor and smart-phone devices to fulfill the ubiquitous computing vision, the-state-of-the-art falls short of this vision. We argue that the reason for this gap is the lack of an infrastructure to task/utilize these devices for collaboration. We propose that microblogging services like Twitter can provide an “open” publish-subscribe infrastructure for sensors and smartphones,...
