{"url":"/dataset/listops","name":"ListOps","full_name":"ListOps","description_markdown":"The ListOps examples are comprised of summary operations on lists of single digit integers, written in prefix notation. The full sequence has a corresponding solution which is\r\nalso a single-digit integer, thus making it a ten-way balanced classification problem. For example, [MAX 2 9 [MIN 4 7 ] 0 ] has the solution 9. Each operation has a corresponding closing square bracket that defines the list of numbers for the operation. In this example, MIN operates on {4, 7}, while MAX operates on {2, 9, 4, 0}. \r\n\r\nSource: [ListOps: A Diagnostic Dataset for Latent Tree Learning](https://arxiv.org/pdf/1804.06028v1.pdf)","description_withheld":null,"homepage":"https://github.com/NYU-MLL/spinn/tree/listops-release","introduced_date":"2018-04-17","introduced_date_note":null,"introduced_by":{"paper":"/paper/listops-a-diagnostic-dataset-for-latent-tree","title":"ListOps: A Diagnostic Dataset for Latent Tree Learning","first_author":"Nikita Nangia","url":null},"license":{"name":"Custom","url":"https://github.com/NYU-MLL/spinn/tree/listops-release"},"modalities":[{"name":"Texts","url":"/datasets/modality/texts"}],"tasks":[{"name":"Natural Language Inference","url":"/task/natural-language-inference","datasets_with_task":"/datasets/task/natural-language-inference"},{"name":"Structured Prediction","url":"/task/structured-prediction","datasets_with_task":"/datasets/task/structured-prediction"},{"name":"ListOps","url":"/task/listops","datasets_with_task":"/datasets/task/listops"}],"languages":[],"variants":["ListOps"],"data_loaders":[{"repo":"https://github.com/NYU-MLL/spinn","url":"https://github.com/NYU-MLL/spinn","frameworks":["pytorch"]}],"num_papers_in_archive":97,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[],"papers_with_a_benchmark_row":[],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":0,"samples_harvested":0,"samples_ran":0,"samples_unverified":0,"pointer_only_for_licence":0,"papers_with_no_sample_that_ran":0,"note":"the per-paper counts above, summed; not a rate"},"papers_note":"The archive never published its papers-using-dataset list; these are papers with a leaderboard row on this dataset's benchmarks."}
