Biography:
- Current Academic Activities:
- I am a Ph.D. candidate in Computer Science at Indiana
University, Bloomington. In 2012 I expect to graduate. My research focuses on applying statistical natural language processing techniques for sentiment analysis. Specifically, I explore the compositional way that evaluations is expressed toward discourse entities, a topic my collaborators and I call "structural sentiment." My adviser, Prof. Michael
Gasser, heads the HLTDI resarch group where I frequently give talks. You can also find me at the CL Lunch and NaN meetings.
- Current Industrial Activities:
-
- Data scientist at PlaceIQ in New York, NY. More about PlaceIQ here, here, and most recently here.
Adviser to Votizen, Mountain View, CA.
- Summer of 2009:
-
I interned at the Palo Alto Research Center (formally Xerox PARC). I worked with Dr. Ji Fang and Dr. Jessica Staddon on a project in sentiment analysis as a member of the Computing Sciences Lab.
- 2008-2010:
-
I was a scientist at J.D. Power and Associates,
Boulder, CO. Working with Dr. Nicolas Nicolov, I helped to guide the construction of a corpus for
structural sentiment analysis and researched ways of automatically
annotating structural sentiment relations. Please see our ICWSM 2009 and 2010 papers for details on part of this effort.
- 2001-2005:
-
In 2005, I received a B.S. in Computer Science from the University of Pittsburgh. While an undergrad, I worked with Prof. Janyce Wiebe on OpinionFinder, a publicly available system for sentence and expression-level subjectivity analysis.

Unpublished Papers:
Data and software
- You may request the JDPA Sentiment
Corpus (used in Kessler and Nicolov [2009] and Kessler et al. [2010]) through the official website.
- The lexicon of terms and multi-word units organized by part-of-speech, veridicality (including facticity) can be found here. These terms, when selected for by syntactic templates outlined in the ICWSM 2008 paper can be used to accurately predict the veridicity of an embeded, finite clause. This an important step in recognizing textual entailment and paraphrase.
