Mobile devices play a significant part in a user’s communication methods and much data that they read and write is received and sent via mobile phones, for instance SMS messages, e-mails, Twitter tweets and social media networking feeds. One of the main goals is to make people aware of how much negative and positive content they read and write via their mobile phones. Existing sentiment analysi...

Low-level sensors can provide surprisingly high-level information about social interactions. The goal of this thesis is to define the components of a framework for sensing social context with mobile devices. We describe several sensing technologies – including infrared transceivers, radio frequency scanners, and accelerometers – that both capture social signals and meet the design constraints o...

The processing capabilities of mobile devices coupled with portable and wearable sensors provide the basis for new context-aware services and applications tailored to the user environment and its daily activities. In this article, we describe the approach developed within the UPCASE project, which makes use of sensors available in the mobile device as well as sensors externally connected via Bl...

Trust is crucial for mobile communications. However, how to manage trust in mobile enterprise networking among various mobile devices is problematic for companies using mobile enterprise solutions. This paper presents a trust management system in an enterprise’s virtual private networks (VPN). The system supports confidential content management and overcomes the diversity support of security in...

Social network information is now being used in ways for which it may have not been originally intended. In particular, increased use of smartphones capable of running applications which access social network information enable applications to be aware of a user’s position and preferences. However, current models for exchange of this information require users to compromise their privacy. We pre...

This demonstration presents AdSocial, a software platform supporting social network applications in ad hoc networks. AdSocial targets small-scale scenarios such as friends playing a game on the train or co-workers sharing calendar information. Moreover, AdSocial is specifically designed to run on resource-constrained mobile devices, such as mobile phones. By using a simple and efficient data pi...

Next generation networks will certainly face requesting access from different parts of the network. The heterogeneity of communication and application software’s changing situations in the environment, from the users, the operators, the business requirements as well as the technologies. Users will be more and more mobile, protocols, etc. will increase and render the network more complex to mana...

Mobile ad hoc social networks are selfconfiguring social networks that connect users using mobile devices, such as laptops, PDAs, and cellular phones. These social networks facilitate users to form virtual communities of similar interests or commonalities. This paper proposes semantics-based mobile social network (SMSN), a novel framework of a fully functional mobile ad hoc social network that ...

Data mining is likely to be considered a much valuable tool especially when applied to social media. Social media mining is the process of representing, analyzing and extracting useful patterns from data in social media, resulting from social interactions. Since its release in 2011 WeChat quickly became the most fast-growing networking mobile app in China. People of similar interests and backgr...
