Exploiting Social Navigation

Accessing A Learning Object Repository Through A Semantic Layer

This paper describes ongoing work on the issue of exploiting a Learning Object Repository, i.e., a large library of learning resources, which incorporates different and often heterogeneous types of objects, to feed activities to a Virtual Learning Community. These objects include re-usable contents that are described by means of metadata. Our proposal leans on an ontology for interpreting the a...

Querying Similarity in Metric Social Networks

In this paper we tackle the issues of exploiting the concepts of social networking in processing similarity queries in the environment of a P2P network. The processed similarity queries are laying the base on which the relationships among peers are created. Consequently, the communities encompassing similar data emerge in the network. The architecture of the presented metric social network is f...

Nowhere to Hide: Navigating around Privacy in Online Social Networks

In this paper, we introduce a navigation privacy attack, where an external adversary attempts to find a target user by exploiting publicly visible attributes of intermediate users. If such an attack is successful, it implies that a user cannot hide simply by excluding himself from a central directory or search function. The attack exploits the fact that most attributes (such as place of residen...
