• 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

• 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
