Welcome
Welcome to the webpage of David Ahn. I am the manager of ranking at Powerset (which has recently been acquired by Microsoft). For three years from 2004 to 2007, I was a postdoctoral researcher in the Information and Language Processing Systems group in the Informatics Institute at the University of Amsterdam.
I was in Amsterdam from February, 2004 through June, 2007. Before that, I spent two months at home in New Jersey writing up my PhD thesis, which I defended on March 22, 2004 in the Computer Science department of the University of Rochester. I spent six and a half years as a PhD student in Rochester, including three four-month stays in Palo Alto at FXPAL (most recently in the fall of 2003) and Xerox PARC.

Research activities
My research interests lie in the intersection of semantics, pragmatics, and applied natural language processing. I am particularly interested in context-dependent aspects of language (such as anaphora and presupposition) and the representation of temporal information in natural language (and, of course, the interaction of the two). The research project through which I am currently funded (ITEQA: Inference for TEmporal Question Answering) investigates the use of temporal information in question-answering.
For more information on my research interests, see my research page.

Other activites
I have two primary pursuits outside of my academic life: music and endurance sports. I sing in several choirs in Amsterdam, and I recently completed my first marathon (the Amsterdam Marathon, in 3:44:09).
