Weaving a Distributed, Semantic Social Network for Mobile Users

Abstract

Smartphones, which contain a large number of sensors and integrated devices, are becoming increasingly powerful and fully featured computing platforms in our pockets. For many people they already replace the computer as their window to the Internet, to the Web as well as to social networks. Hence, the management and presentation of information about contacts, social relationships and associated information is one of the main requirements and features of today's smartphones. The problem is currently solved only for centralized proprietary platforms (such as Google mail, contacts & calendar) as well as data-silo-like social networks (e.g. Facebook). Within the Semantic Web initiative standards and best-practices for social, Semantic Web applications such as FOAF emerged. However, there is no comprehensive strategy, how these technologies can be used efficiently in a mobile environment. In this paper we present the architecture as well as the implementation of a mobile Social Semantic Web framework, which weaves a distributed social network based on semantic technologies.

Privacy-Aware and Scalable Content Dissemination in Distributed Social Networks

“…While using a publish-subscribe approach, information is sent from the provider to all its subscriber (one of the reason while PuSH was build). More recently, [20] is at a close proximity to our work but on mobile platforms. They provide a semantic social network for mobile platforms, but do not tackle the privacy aspect.…”

“…Users can either make their account public (by default, everyone can view their content) or protected (only approved followers can view their content). Yet, the lack of fine-grained privacy policies caused several incidents, such as people being fired because some content reached undesired people in their network 20 . Using PuSH in OSNs brings similar patterns where a publisher can either broadcast his data to all the subscribers or not.…”

Social Multimedia Networks Behaviour Model & Architecture

“…These advantages are as follows: This section begins with a discussion of design principles, followed by a brief explanation of four architectural layers, namely, the data, protocol, service and application layers. A network architecture composed of these layers was developed by Tramp et al in 2012. This section also describes how this social network architecture works.…”

Real-Time Data Aggregation in Distributed Enterprise Social Platforms

“…Once the social platform is operational and social connections are established, it is important to gather and reuse information available in this network. Thus, a distributed social network requires efficient information aggregation and delivery tools to allow for timely updates and retrieval of relevant content [21]. To address this challenge, the Semantic Web practitioners propose to use RDF to capture social data [20] and integrate RDF content across the organization.…”
