Short Bio

My research field is Artificial Intelligence, focusing on corpus based approaches for knowledge acquisition and retrieval. I got my Ph.D. in Information and Communication Technologies at the University of Trento in December 2005. I'm author of more than thirty scientific publications, published in top level conference proceedings and international journals. Currently, I'm working as a research consultant for both the Cognitive and Communication Technologies (TCC) division at FBK-irst, Trento, and the Laboratory for Applied Ontology (LOA) at the Institute for Cognitive Sciences and Technology of the National Research Council (ISTC-CNR), Rome. My research work includes the participation at many UE founded projects, program committee membership at international conferences, students supervision, teaching in advanced courses and the development of state of the art NLP tools, some of them reporting the best performances in the context of international evaluation challenges. Apart from my academic activities, I'm also collaborating with some ITC company as a consultant for technology transfer.
