The rapid growth of peer-to-peer networks and social networking websites has demonstrated the internet’s potential as a medium for grassroots collaboration. This report describes ongoing research into the use of friend-to-friend overlay networks for censorship-resistant communication. Decentralised mechanisms for resource allocation, unforgeable acknowledgements and adaptive routing are propose...

Let E be a compact set of positive logarithmic capacity in the complex plane and let {Pn(z)}1 be a sequence of asymptotically extremal monic polynomials for E in the sense that lim sup n→∞ ∥Pn∥ E ≤ cap(E). The purpose of this note is to provide sufficient geometric conditions on E under which the (full) sequence of normalized counting measures of the zeros of {Pn} converges in the weak-star top...

The friend of a friend (FOAF) vocabulary is widely used on the Web to describe individual people and their properties. Since FOAF does not require a unique ID for a person, it is not clear when two FOAF agents should be linked as coreferent, i.e., denote the same person in the world. One approach is to use the presence of inverse functional properties (e.g., foaf:mbox) as evidence that two indi...

This paper seeks to find characteristics of relationships between developers within various clusters of FLOSS ecosystems. We have mined the repository of the open source programming language Ruby, and linked developers and projects on the basis of collaboration. We used Social Network Analysis, and more specifically, the concept of modularity to expose underlying clusters or sub-communities. A ...

Social networks are important for the Semantic Web. Several means can be used to obtain social networks: using social networking services, aggregating Friendof-a-Friend (FOAF) documents, mining text information on the Web or in e-mail messages, and observing face-to-face communication using sensors. Integrating multiple social networks is a key issue for further utilization of social networks i...

BACKGROUND The family, and parents in particular, are considered the most important influencers regarding children's energy-balance related behaviours (EBRBs). When children become older and gain more behavioural autonomy regarding different behaviours, the parental influences may become less important and peer influences may gain importance. Therefore the current study aims to investigate simu...

In this work we report about the automatic creation of dynamic user profiles that combine personal data from diverse social networks with context information recorded by IYOUIT, a mobile community service in the field of context awareness. Data mining algorithms are applied to learn about users and their preferences over time. Rich, semantically annotated Friend of a Friend (FOAF) profiles are ...

Increasingly, data is published in the form of semantic graphs. The most notable example is the Linked Open Data (LOD) initiative where an increasing number of data sources are published in the Semantic Web’s Resource Description Framework and where the various data sources are linked to reference one another. In this paper we apply machine learning to semantic graph data and argue that scalabi...

Recommender service systems have been widely and successfully applied in e-commerce to provide personalized recommendations to customers nowadays. The tremendous growth in the amount of available information and the number of visitors to websites poses some challenges for recommender service systems such as poor prediction accuracy, scalability, and dynamic changes of users. To address these is...
