Welcome to Maurizio Atzori's Home

Short CV

Maurizio Atzori was born in 1978 in Italy. He graduated in Computer Science (Informatica) summa cum laude in 2002, from the University of Pisa. He holds a PhD in Computer Science from the School for Graduate Studies “Galileo Galilei”, University of Pisa, obtained in 2006. He has been member of the ISTI-CNR, holding a research fellowship from CNR of Pisa, and a member of Knowledge Discovery and Delivery Laboratory. He has been visiting scholar at Purdue University (Indiana, USA), working with Prof. Christopher W. Clifton and his research team. He has been visiting resercher working with Prof. Yucel Saygin at Sabanci University (Istanbul, Turkey) and at UCLA, collaborating with Prof. Carlo Zaniolo. Since December 2010 he is Assistant Professor (Ricercatore Universitario, Professore Aggregato) at the Department of Mathematics and Computer Science of the University of Cagliari (Italy). His major research interests regard database and dataspaces, data mining, knowledge graphs and privacy-preserving algorithms for data management.

Software and Tools

• SWiPE Searching WikiPedia by Example, as published at WWW2012 and featured by the international magazine New Scientist, ZDNet, Communications of the ACM, KurzweilAI and translated in several languages

"By making Wikipedia search simple, though, SWiPE has the potential to bring this benefit to a far greater audience. I, for one, can’t wait to try it out myself." (Lee Feigenbaum, W3C SPARQL WG co-Chair)

• CodeOntology RFD-ization of source code and use of SPARQL for finding design patterns over code

• Web of Functions Higher-order interoperable functions within any SPARQL endpoint

• runSPARQL A tool to compute Recursive SPARQL Queries.

• rankProp A tool to rank RDF properties of DBpedia entities, based on MLR algorithms.

• Qpedia A visual query interface focused on mobile devices. It compiles queries to SPARQL and run them against DBpedia servers.

• Java Privacy-Preserving Pattern Discovery Package (jp3d) A pure java package for privacy-preserving pattern discovery. MathCollection, an extension for the Java Collection Framework by Dietmar Lippold, is required. See CNR description for further details.

• k-Privacy A pure java application for table anonymization through k-anonymity generalization and suppression. It has both console and graphical user interface. Joint work with Davide Carfi. See CNR description for further details.

• Privacy-Preserving Distributed Data Mining Library (PPDDM-Lib) An open source ANSI C/C++ library of functions and protocols useful to exchange sensible information while computing Data Mining Models from several servers, as described in Clifton et al., 2003. The OpenSSL Toolkit is required. Joint work with Daniele Sgandurra, developed at ISTI-CNR, Pisa.

I am also developing a number of other applications in the fields of abduction, data privacy, and data mining. I planned to publish them here as soon as the documentation is ready. If you need details on experiments on my papers or software published here, please feel free to email me.
