A brief summary of the results of the recent Kaggle Text Normalization Challenge.
I am a computational linguist (which means that I have some things in common with grapefruit).
I am a Research Scientist at Google in New York.
From January, 2009, through October 2012, I was a professor at the Center for Spoken Language Understanding at the Oregon Health and Science University.
Prior to going to OHSU, I was a professor in the departments of Linguistics and Electrical and Computer Engineering at the University of Illinois at Urbana-Champaign. I was also a full-time faculty member at the Beckman Institute. I still hold adjunct positions in Linguistics and ECE at UIUC.
I continue to maintain some "side-bar interests" including computational models of the early evolution of writing, the statistical properties of non-linguistic symbol systems, and collaborating on a translation of Wolfgang von Kempelen's Mechanismus der menschlichen Sprache, which should be forthcoming later in 2016 or early 2017.
Prior to coming to Google I was working on several projects, some of which are still current in the sense that my collaborators are still working on them.
I am very interested in writing systems; see some work I was doing on approximate string matching in the Easter Island rongorongo script. I also ran (with Jerry Packard) a reading group centered around Hannas' controversial thesis relating Asia's supposed technological creativity gap, with the Chinese writing system.
Before joining Ken's department I worked in the Human/Computer Interaction Research Department headed by Candy Kamm. My most recent project in that department was WordsEye, an automatic text-to-scene conversion system. The WordsEye technology is now being developed at Semantic Light, LLC. WordsEye is particularly good for creating surrealistic images that I can easily conceive of but are well beyond my artistic ability to execute. All of the following images were generated from text descriptions of the scene. Click on the images to see the text that generated the scene:

|Some photos of my recently acquired 1791 first edition of Wolfgang von Kempelen's Mechanismus der menschlichen Sprache nebst der Beschreibung seiner sprechenden Maschine. This is the very first serious study of articulatory phonetics, and the first description of a mechanical speech synthesizer.|

|A refutation of the supposed evidence from Rao and colleagues that the Indus Valley symbol system was a script. Also: a simple python program that does a pretty good simulation of Rao et al's results, assuming a Zipfian distribution of characters for a 400-character vocabulary, and conditional independence of the characters. In other words, you get the same behavior as Rao shows for the Indus corpus even with a model that has no syntactic dependence between the glyphs whatsoever. See also Mark Liberman's entry on the Language Log, and Fernando Pereira's skewering of this paper, as well as Science. Here is the letter that we sent to Science, but which they refused to publish. Of course they cited lack of space. But it's very hard to see what kind of letter would be more worthy of space than one that points out a set of fatal flaws in a "peer-reviewed" publication that appeared in Science. Finally, here's a plot that demonstrates, using Rao et al's technique, that European heraldry is a linguistic symbol system. It also seems to show that Amharic (a semitic language) is closely related to the Dravidian language Tamil.|

article with Steve Farmer and Michael Witzel in the Electronic
Journal of Vedic Studies, 11(2), 2004, argues that the
so-called Indus Valley script was not a writing system at all.
The December 17, 2004 issue of Science ran a feature on our work.
Evidently this article has caused a bit of a stir in some circles. See the related challenge (worth $10,000!!) to prove that I'm an idiot.
