Large scale ontology applications require efficient and robust description logic (DL) reasoning services. Expressive DLs usually have very high worst case complexity while tractab...
We address the problem of answering conjunctive queries over knowledge bases, specified by sets of first-order sentences called tuple-generating dependencies (TGDs). This problem i...
Abstract. We present and discuss a formal, high-level approach to the specification and composition of interaction protocols for service-oriented systems. This work is being develo...
Although necessary, learning to discover new solutions is often long and difficult, even for supposedly simple tasks such as counting. On the other hand, learning by imitation pr...
Firewalls are a cornerstone of todays security infrastructure for networks. Their configuration, implementing a firewall policy, is inherently complex, hard to understand, and diff...
