Internships:
• Summer 2009 – Internship at Google. The project was on using language models
for data quality assurance in Google Local Business Center.
• Summer 2008 – Research internship at Honda Research Institute. The project was
on measuring coherence in spoken dialog.
• Summer 2007 – Research internship at Honda Research Institute. The project was
on using encyclopedic knowledge for understanding spoken utterances.
• Fall 2006 - Consultant for Microsoft. Extension of summer 2006 internship
(identifying sentiment in customer reviews).
• Summer 2006 – Research internship at Microsoft. The project was on identifying
the sentiment of product reviews.
Other Projects/Employment:
• Spring 2005 : Scientific programmer at Software Quality Engineering / Data
Mining Lab, Ben-Gurion University (BGU), partially supported by USA Space and

3. Naval Warfare Systems Command Grant No. N00039-01-1-2248. The project was on
generating ’good’ test cases using Gentetic Algorithms.
• 2003 - 2004 : Research Assistant for BGU and ‘CVidya Networks’ joint research in
Data Mining, funded by the Israeli Ministry of Industry and Trade. (The project was
on transferring association rules across databases. This is an adaptation problem,
where we are given a classifier that performs well on domain A, and we want to apply
it to domain B, which is similar, but has somewhat different properties).
• 2002 - 2003 : Research Assistant for BGU and ‘SAP-Portals’ joint research on
schema matching, funded by the Israeli Ministry of Industry and Trade. (This project
has originated my M.Sc. thesis. The task was discovering synonyms across database
schemas).
Teaching experience:
• Fall 2005-Spring 2007: Teaching Assistant at University of Illinois at Urbana-
Champaign (Discrete Math.)
• 2002 - 2005 : Teaching Assistant at Ben-Gurion University (BGU).
Professional Activities:
• Reviewer for CoNLL-2009
• Reviewer for AAAI 2008
• Reviewer for COLING 2008
• Reviewer for ACL 2007
Education:
• Fall 2005 - Current : Phd candidate, University of Illinois at Urbana-Champaign.
Thesis advisor: Prof. Dan Roth. Areas: Machine Learning, Natural Language
Processing.
• Spring 2004 - Fall 2005 : Phd candidate, Ben-Gurion University, Israel.
• 2002 - 2004 : M.Sc. at Ben-Gurion University (Cum Laude). Thesis title: “Schema
Matching through Schema Understanding.” (Thesis advisor: Prof. Solomon Eyal
Shimony. Thesis description: automatic discovery of synonyms in Web interfaces and
in database schemas. For example, when booking airplane tickets, ‘Cabin Preference’
can be used instead of ‘Class’.)
• 1996 - 2002 : B.Sc. at Ben-Gurion University (Cum Laude)
