Research with LensKit

LensKit is intended to be particularly useful in recommender systems research. See the Experiment Quickstart to get started using LensKit in your own research.

If you publish research that uses LensKit, please cite:

Michael D. Ekstrand, Michael Ludwig, Joseph A. Konstan, and John T. Riedl. 2011. Rethinking The Recommender Research Ecosystem: Reproducibility, Openness, and LensKit. In Proceedings of the Fifth ACM Conference on Recommender Systems (RecSys ’11). ACM, New York, NY, USA, 133-140. DOI=10.1145/2043932.2043958.

For your convenience, here is the BibTeX:

    title = "Rethinking the Recommender Research Ecosystem: Reproducibility, Openness, and {LensKit}",
    booktitle = "Proceedings of the Fifth {ACM} Conference on Recommender Systems",
    author = "Ekstrand, Michael D and Ludwig, Michael and Konstan, Joseph A and Riedl, John T",
    publisher = "ACM",
    pages = "133--140",
    series = "RecSys '11",
    year =  2011,
    url = "",
    conference = "RecSys '11",
    doi = "10.1145/2043932.2043958"

We would also appreciate it if you could send a PDF and citation for your article to, so we can know where all LensKit is being used.
