$\mathcal{DS}^{4}$ : Introducing Semantic Friendship in Distributed Social Networks

Towards content-based publish/subscribe for distributed social networks

“…System implementation. To highlight the feasibility of the proposed architecture we developed a prototype system based on the DS 4 [11] distributed social network. The proofof-concept prototype was build upon Microsoft .NET Framework v4.5, using C#, the WPF and WCF libraries for the graphical user interface and the communication protocols respectively, the Lucene v3.0.3 library for the indexing and handling of all content management tasks, and the log4net library for logging and reporting.…”

“…Our work builds upon research results from the peer-to-peer paradigm, such as those utilizing unstructured, small-world, and semantic overlay networks [9,10,16]. Such decentralised approaches to social networking have also been adopted both by academia and industry by building a number of distributed social platforms [14,3,3,15] and distributed social data management systems [6,5,4,7,11,8]. Although all these approaches offer different types of distributed social networks that allow users to create communities, share content, and send messages, none of them focuses on supporting content-based publish/subscribe (pub/sub) functionality in the context of distributed social networks.…”

“…To the best of knowledge, there are no such systems in the literature that offers all these features at the same time. To do so we leverage on the concepts of semantic friendship [11] between users and approximate pub/sub [18]. In our design, semantic friendship emerges from common user interests/profiles by establishing connections among semantically similar nodes (in addition to the social connections) and by discarding connections that are outdated or pointing to dissimilar nodes.…”
