Searching for new ways of thinking in programming & working with data

I'm a visiting researcher at the Alan Turing Institute working on tools for data-driven storytelling. I also work closely with the F# team in Microsoft Research and I recently submitted my PhD thesis at University of Cambridge. If you read 3 of my papers, consider the following ones!

Type Providers

F# Data infers types from sample XML and JSON documents and safely embed them into F#. Our PLDI 2016 paper is an ACM SIGPLAN Research Highligt.

Coeffects

Coeffects are theory of context-aware programming languages developed in my PhD thesis. Check out our ICFP 2014 paper or my interactive essay.

Philosophy

How different communities approach errors? My paper on history and philosophy of errors published in ‹Programming› 2017 was selected as reviewers choice.

The Gamma Data Exploration through Iterative Prompting

Tomas Petricek

Unpublished draft

Governments, non-profit organizations and citizen initiatives publish increasing amounts of data, but extracting insights from such data and presenting them to the public is hard. First, data comes in a variety of formats that each requires a different tool. Second, many data exploration tools do not reveal how a result was obtained, making it difficult to reproduce the results and check how they were obtained.

We contribute The Gamma, a novel data exploration environment for non-experts. The Gamma is based on a single interaction principle and using it results in transparent and reproducible scripts. This allows transfer of knowledge from one data source to another and learning from previously created data analyses. We evaluate the usability and learnability of The Gamma through a user study on non-technical employees of a research institute. We argue that the our approach allows journalists and the public to benefit from the rise of open data, by making data exploration easier, more transparent and more reproducible.
