Software and Data

I have built several open-source software packages and data sets in the course of my research and other work. Open-source software distribution and open data are key pieces of my research dissemination strategy. My most significant development efforts are:

  • LensKit, a toolkit for building, researching, and studying recommender systems. As of Nov. 1, 2022, the original Java software (in development 2010–2018; paper RecSys11) is known to be used in 70 papers and theses and was used by over 2500 students to complete programming assignments in the Recommender Systems MOOC. The Python software (2018–, papers CIKM20-lk and Reveal18-lk) is used in over 30 papers, theses, and educational resources, including the PBS show Crash Course AI, and has been downloaded over 9000 times from the Python Package Index in the last 6 months (according to PyPIStats). The current version is 0.14.2, released on July 16, 2022; it is the 23rd release of LensKit for Python. https://lenskit.org (current list of known uses: https://lenskit.org/research/)
  • Book Data Tools, software tools to integrate multiple public sources of book and book consumption data into a data set for studying social effects in book publication, reading, and recommendation. Used in UMUAI21 and RecSys18. https://bookdata.piret.info

My work has also produced a number of utility packages to support this software and other efforts, including:

  • seedbank, a Python package for consistently seeding random number generators. https://seedbank.lenskit.org
  • csr, a Python package for managing sparse matrices in CSR format compatible with the Numba JIT for scientific python, and with Intel MKL acceleration for several operations. https://csr.lenskit.org
  • binpickle, a Python package for saving scientific data structures (such as machine learning models) to disk in either compressed or memory-mappable format. LensKit uses this package to serialize models for both storage and shared-memory parallelism. https://binpickle.lenskit.org
  • happylog, a Rust package for easily configuring log output for command-line programs. https://github.com/mdekstrand/happylog
  • Grapht, a dependency injection framework for Java with novel configuration and static analysis capabilities (paper JOT16). http://grapht.grouplens.org
