[CS Seminars at UniBz] Grigoris Antoniou, Wed 16th December 2009, 13:00-14:00

by CS Faculty Seminar

I am pleased to invite you to the following seminar of the Faculty of Computer Science of Bolzano-Bozen. DATE: Wednesday, 16 December, 13:00-14:00 PLACE: Room F001, (Design Building, Universitätsplatz 1 - piazza Università, 1, Bozen-Bolzano) TITLE: Reasoning about Context with Conflicts in Ambient Intelligence Environments SPEAKER: Prof. Grigoris Antoniou (University of Crete and Information Systems Laboratory, FORTH, Heraklion, Greece) ABSTRACT: The imperfect nature of context in Ambient Intelligence (AmI) environments, and the special characteristics of the entities that possess and share the available context information render contextual reasoning a very challenging task. The accomplishment of this task requires formal models that handle the involved entities as autonomous logic-based agents, and provide methods for handling the imperfect and distributed nature of context. In this talk, we propose a solution based on the Multi-Context Systems formalism, in which local context knowledge of AmI agents is encoded in rule theories (contexts), and information flow between agents is achieved through mapping rules associating concepts used by different contexts. To handle the imperfect nature of context, we extend Multi-Context Systems with non-monotonic features: local defeasible theories, defeasible mappings, and a preference relation on the system contexts. We present this novel representation model, called Contextual Defeasible Logic, describe its argumentation semantics, propose a sound and complete algorithm for distributed query evaluation, and a number of variants for this algorithm. SPEAKER'S HOMEPAGE: http://www.ics.forth.gr/~antoniou/ CURRICULUM VITAE: Grigoris Antoniou is Professor of Computer Science at the University of Crete, and Head of the Information Systems Laboratory at FORTH-ICS, the top-rated ICT research institute in Greece. Previously he has held professorial appointments at Griffith University, Australia, and the University of Bremen, Germany. His research interests lie in semantic technologies, particularly knowledge representation and reasoning, and its application to the web and ambient intelligence. He has published over 150 technical papers in scientific journals and conferences. He is author of three books with international publishers (MIT Press, Addison-Wesley); his book "A Semantic Web Primer" is internationally the standard textbook in the area, and has been or is about to be translated to Japanese, Chinese, Korean, Spanish and Greek. In recognition of his work, he was elected an ECCAI Fellow in 2006, joining the prestigious list of the best AI researchers in Europe. Since 2008 he is member of the ECCAI Board.

apt-get install --yes

by Davide

Lanciando questo comando: apt-get install --yes linux-image-server che vorrei fosse eseguito in batch, ad un certo punto si apre un paio di dialoghi a chiedermi informazioni di grub che neanche mi interessa (ma sembra una sua dipendenza) E' un errore che lo faccia col parametro --yes e/o si puo' disabilitare la richiesta di info all'utente?

subvesion e atomic commit - warning

by Davide

Ciao, a quanto risaputo subversion fa dei commit atomici, nel senso che tutto il materiale e salvato e una nuova versione e creata solo se tutti i singoli file sono stati salvati correttamente. Ho notato pero' che se lo spazio su disco di dove e' il repository non e' sufficiente per l'operazione, allora il commit non e' atomico!!! Ci si trova con una situazione rovinata. Okkio!
