We present an architecture1 designed for alert verification (i.e., to reduce false positives) in network intrusion-detection systems. Our technique is based on a systematic (and a...

In long-term, recurring contractual relationships, which are common in the B2B-area, reputation and trust play an outstanding role. The impact of reputation and price-based assess...
Complex objects can often be conveniently represented by finite sets of simpler components, such as images by sets of patches or texts by bags of words. We study the class of posi...
