Since August 2009, I have been a Research Scientist at the USC Information Sciences Institute. From July 2011, I am also a Research Assistant Professor at the University of Southern California. My research interests lie in large scale knowledge acquisition from the Web, lexical semantics, ontology population, sentiment analysis, metaphors and information extraction.
