Computational Linguist

Dan Simonson is a Senior Computational Linguist at BlackBoiler LLC, working to improve the automation of contract negotiation. He completed his PhD in computational linguistics at Georgetown University in the Department of Linguistics. He's most interested in using linguistics and natual language processing to take objective and interesting slices of the real world to yield insight and understanding and, if possible, to use natural language processing to solve problems of direct material value. In particular, this has led him to pursue problems related to narrative schemas, information extraction and retrieval, semantic modality, critical discourse analysis, and applying these topics to one another.

Dan defended his dissertation, Investigations of the Properties of Narrative Schemas, on November 17th, 2017, and the dissertation was accepted by the grad school on April 25th, 2018. His dissertation committee consisted of Tony Davis, Amir Zeldes, and Nate Chambers. He recently accepted a full-time position at a DC Area start-up where he's been working part-time for the past two years. Things have been going, in his words, "pretty rad."

Dan is most easily found in rooms with free coffee and on a bicycle. He tried both at the same time once in his youth and ended up burning his hand.

He also feels very weird writing about himself in the third person and will cease immediately.

Tools and Goodies

Bash Your Way into Bash

Bash Your Way into Bash is a tutorial for using bash. It's for people who have no experience using command line interfaces.

ft library for Python

ft is a library for dealing with lists of dictionaries in Python. It makes counting and finding things eas(y|ier). You can get ft off of pip (pip install ft). I've made an official page here with some code examples; the in-code documentation is pretty solid.

Simple Python Twitter Scraper (SPyTS)

SPyTS is a tool for scraping tweets. For us plebs who don't have firehose access to Twitter, It spreads queries out over as evenly as possible of a period and prevents exceeding Twitter's API rate limits. SPyTS is available on github.

Narrative Schemas

A lot of what we know is grounded in stories. Some stories tend to repeat themselves, and once they do enough, it's been hypothesized that we genericize the stories into something called a schema. I work to extract this type of world knowledge from language data and apply it to problems that would otherwise be inaccessible to quantitative analysis.

My dissertation focuses on the extraction of these sorts of schemas, to understand their distribution and properties, and how to apply this knowledge to practical, real-world tasks.

Throughout my time at Georgetown, I have been involved in a project building a theory and corpus of gradable modal expressions [NSF-funded, BCS-1053038]. Modal expressions are those that express possibilities. They span all parts of speech.

I played a number of roles on this project. During the experimental aspects of the project, where the annotation guidelines were developed and tested, I was responsible for reporting interannotator agreement scores. During the corpus construction component, I built and maintained a cross-platform tool for adjudicating annotator output. Throughout both stages of the project, I managed data as it flowed between phases of the project.

Undergraduate Research in Astronomy

During my undergrad, I was a physics major and participated in astronomy research under the guidance of Harold Butner. I presented posters in two annual meetings of the American Astronomical Society as results of this research. These proceedings derived from two separate projects involving the DEBRIS target set, a search for binary stars using the Herschel Space Observatory. The first was a search for estimates of stellar age in the literature of our project's target stars; the second reported preliminary results of an observing run in the infrared identifying candidate binaries.

Pluto never should have been planet.

My first website was D's C&c Page. I lost the whole thing when, for some reason, Geocities decided I violated their TOS. No explanation was given.

wow such linguistics
