I am a PhD student at the School of Computer Science and Engineering of The Hebrew University of Jerusalem. I am a member of the Computational Linguistics and Natural Language Processing lab and my advisor is Prof. Ari Rappoport. I studied mathematics and cognitive sciences in the Hebrew University, and graduated with a B.Sc in 2006.
My main research interest (for now) is verb argument structure and its interface with syntax and lexical semantics. In particular, I am interested in minimally supervised approaches, motivated by linguistic/cognitive knowledge/intuition. I am hoping some of the work in this field may teach us something new and interesting about language.
I collaborate with Roi Reichart and Roy Schwartz from our lab.
Since 2009 I am a member of the Azrieli Fellows Program.
I was a program committee member in IJCAI 2011, EMNLP 2011, IJCNLP 2011 and EMNLP 2012. I co-organized (with Anna Korhonen, Roi Reichart and Ari Rappoport) two workshops on Unsupervised Learning in NLP. The first was held in 2011 as an EMNLP workshop (our site). The second was held jointly with ROBUS (organized by Chris Biemann and Anders Sogaard) as an EACL 2012 workshop (our site).
