Several solutions have been proposed to provide authentication and safe encryption for Wifi networks in order to overcome the limitation of WEP based security. This document descr...
We document a connection between constraint reasoning and probabilistic reasoning. We present an algorithm, called probabilistic arc consistency, which is both a generalization of...
Social networks play important roles in the Semantic Web: knowledge management, information retrieval, ubiquitous computing, and so on. We propose a social network extraction syst...
