    Parsers and Calculators

    • A proof-of-concept type-driven parser and interpreter. Built with Simon Charlow using Haskell and Purescript. See the code, which is really just compositional semantics, here, along with a brief description of what you can do.

    • A dynamic semantics (PLA) calculator, showing how the state changes in response to various formulas. The calculator is written in Elm, a purely functional language, so the code is the semantics. Also check out Simon Charlow's command line version, and Chris Potts's original web app.

    • I'm listed on the ever-growing credits reel of The Lambda Calculator, "an interactive, graphical application to help students of natural language semantics practice derivations in the typed lambda calculus".

    Lecture Notes

    • Slides from a 2022 ESSLLI course co-taught with Simon Charlow on functional programming techniques for natural language semantics.

    • Notes, papers, and code from a much earlier iteration of the course above led by Chris Barker.

    Reference Fragments for Semantics Papers

    Experiments, Simulations, Data

    • A Jupyter notebook computing and demonstrating the Rational Speech Act models reported in Bumford and Rett 2020, "Rationalizing evaluativity"

    • The javascript and related source material for a grammar learning experiment to be online using psiTurk. The experiment elicits production data during exposure to an artificial language, and explores the role of expectation in complex pattern learning.

  • About dbumford@ucla.edu

    I am an Assistant Professor in UCLA's Department of Linguistics. My research concentrates on formal semantics and pragmatics, especially in their interfaces with theoretical computer science. My dissertation explored ways in which dynamic semantics and split-scope mechanisms can help make sense of apparently indefinite definite descriptions. Related to this, I have argued for particular views of the lexical semantics of distributive universals and superlative adjectives based on their interactions with structures for binding and anaphora. For much of this work, I have tried to incorporate techniques from functional programming and type theory into linguistic analysis, looking especially at how the algebraic structures used to model computational side effects can be leveraged to organize natural language composition. I have also worked on pragmatic models integrating rational inference over dynamic denotations. And I have participated in projects investigating semantic parsing, statistical grammar learning, and the implicatures of clefts and exclusives across languages.
