  Bio:
Jason Kessler is a lead data scientist at CDK Global, where he analyzes language use and consumer behavior in the online auto-shopping ecosystem. Prior to joining CDK, Jason was the founding data scientist at PlaceIQ and worked as a research scientist for JD Power and Associates. He has published peer-reviewed papers on algorithms and corpora for sentiment and belief analysis, and has sat on program committees and reviewed for several AI and NLP conferences. Most recently, he has conducted research on identifying persuasive and influential language and the visualization of differing corpora.

  • Scattertext, a Python term importance and text visualization package.
  • Age from Name, a Python package to estimate a person's age and generation from their name and gender.
  • 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 embedded, finite clause. This an important step in recognizing textual entailment and paraphrase.
Industrial Activities:
2013-present
Lead (as of Sept. 2016) data scientist at CDK Global, Seattle.
2010-2012
Founding data scientist at PlaceIQ, NYC.
2010-2013

2008-2010:
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 200 and, 2010 papers, as well as our recent Handbook of Linguistic Annotation chapter for details on this effort.
Summer of 2009:
Research Intern at Palo Alto Research Center (formally Xerox PARC). I worked on a project in sentiment analysis as a member of the Computing Sciences Lab.
Service: Contact: Academic Activities:
Ph.D. candidate in Computer Science at Indiana University, Bloomington. My research focused 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."
2001-2005:
In 2005, I received a B.S. in Computer Science from the University of Pittsburgh. While an undergrad, I worked on OpinionFinder, a publicly available system for sentence and expression-level subjectivity analysis.
