This paper is presented the study of the social influence by using social features in fitness mobile applications and habit that persuades the working-aged people, in the context of continuous fitness mobile application usage to promote the physical activity. Our conceptual model consisted of Habit and Social Influence. The social features based on the Persuasive Technology (1) Normative Influence,...
With an ever increasing amount of data generated by scientific experiments, social networks and mobile as well as wireless sensor networks, reducing resource consumption by big data applications becomes of paramount importance. Towards this end, filtering data close to the data sources is a common strategy in order to reduce network traffic. Assuming a network of nodes, each potentially generating...
Today, mobile phones due to the rapid growth of new technologies and the emergence of a new generation of smart phones have become more than a communication tool that not only resolves the user's communication needs, but also provide them, services for many applications. List of mobile phone subscribers include slow-level simple concepts such as time and place of calls, talk time, etc. The analysis...
Online social networks have long been studied by researchers to unearth the common patters of socializing among human beings. Recently, there is considerable interest in Internet-of-Things which is an interaction of smart physical objects augmented with sensing devices. However, there is hardly any research on intra-smart object interactions and interactions among smart physical objects and humans...
Opportunistic networking has been proposed to support a number of novel applications, like content sharing or mobile data offloading, that follow a content-centric communication model, i.e., many users are interested in the same content. Users' traffic demand patterns can crucially affect the performance of such applications, but our knowledge about the characteristics of content demand is limited...
Driving is an integral part of our everyday lives, and the average driving time of people globally is increasing to 84 minutes everyday, which is a time when people are uniquely vulnerable. A number of research works have identified that mobile crowd sensing in vehicular social networks (VSNs) can be effectively used for many purposes and bring huge economic benefits, e.g., safety improvement and...
As online social networks have grown in popularity, teenage users have become increasingly exposed to the threats of cyberbullying. The primary goal of this research paper is to investigate cyberbullying behaviors in Vine, a mobile based video-sharing online social network, and design novel approaches to automatically detect instances of cyberbullying over Vine media sessions. We first collect a set...
This paper addresses the task of community detection and proposes a local approach based on a distributed list building, where each vertex broadcasts basic information that only depends on its degree and that of its neighbours. A decentralised external process then unveils the community structure. The relevance of the proposed method is experimentally shown on both artificial and real data.
Trustworthy personal data access control at a semi-trusted or distrusted Cloud Service Provider (CSP) is a practical issue although cloud computing has widely developed. Many existing solutions suffer from high computation and communication costs, and are impractical to deploy in reality due to usability issue. With the rapid growth and popularity of mobile social networking, trust relationships in...
The digitization of social networks has enabled the passive collection of large scale data, which in turn have fostered social studies that have been traditionally dependent on small scale, interview-based data. During the last years, a new class of digital social networks has emerged, namely, location-based social networks (LBSNs). The main interaction between users of an LBSN is location sharing,...
Identity awareness of research data has been introduced as a requirement for open research, transparency and reusability of research data in the context of eScience. This requirement includes the capability of linking research data to researchers, research projects and publications, and identifying the license for the data. This connectivity between research data and other elements in research ecosystems...
Sensor-equipped mobile devices have allowed users to participate in various social networking services while they are on the go. We focus on proximity-based mobile social networking environments where users share information obtained from different places via their mobile devices when they are in proximity. Since people are more likely to share information if they can benefit from the sharing or if...
When mobile device users meet at a certain place, they may share information obtained from some other places. Since people are more likely to share information if they can benefit from the sharing or if they think the information is of interest to other people, there might exist communities where people share information more often with community members. The communities in mobile social networks...
In this work, we explore how information services can be used to improve the travel experience in public transportation and reduce the perceived travel time. More specifically, we describe the creation of a mobile application for assisting passengers, which explores the integration of social networking features into the traveling experience. The overall objective is to understand how social networking...
A smart-phone generates lots of contextual information related with user environment in Social Network Service (SNS). Especially, communication data is an important context to recognize a close-relationship among mobile users. The related works using the communication data in this research area have actively studied. However, the most of the studies were to analyze social network studying on a personal...
Crowdsourcing is a new paradigm that has influenced the businesses, emergency management, collaboration and online interaction. The term crowd source means tapping the power of crowd. Research in crowd sourcing involves issues such as quality of data, incentives, working modal and contracts. This research deals with the issues of uncertainty and quality of social mobile computing systems. It suggests...
With the development of wireless communication, the popularity of smart phones, the increasing of social networking services, mobile social networking has become a hot research topic. The characteristics of mobile devices and requirements of services in social environments raise a challenge on building a platform for mobile social services. In this paper, we elaborate a flexible system architecture...
Mobile social networks give online social networking sites the abilities to extend their services to mobile device users. Smart phones and tablets allow users to interact with others when they are moving. Policy-based management simplifies the management of interaction functionalities by establishing policies to control various activities involved in these functionalities. To detect and resolve potential...
Mobile social applications are becoming increasingly popular with a growing number of users turning to mobile devices for socializing, information sharing, retrieval or related activities, and/or gaming. The increased interest in the domain has resulted in numerous application prototypes being reported in the recent years that combine elements of socializing, gaming, and information related activities,...
