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 permanent faculty at the Department of Mathematics and Computer Science of the University of Cagliari (Italy), Associate Professor since November 2018.

Software and Tools

"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)

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.
