SPACE is built on TripAdvisor hotel reviews and includes a training set of approximately 1.1 million reviews for over 11 thousand hotels.\r\n\r\nFor evaluation, we created a collection of human-written, abstractive opinion summaries for 50 hotels, including high-level general summaries and aspect summaries for six popular aspects: building, cleanliness, food, location, rooms, and service. Every summary is based on 100 input reviews, an order of magnitude increase compared to existing corpora. In total, SPACE contains 1,050 gold standard summaries. You can view the full instructions for out multi-stage annotation procedure here.","description_withheld":null,"homepage":"https://github.com/stangelid/qt","introduced_date":"2020-12-08","introduced_date_note":null,"introduced_by":{"paper":"/paper/extractive-opinion-summarization-in-quantized","title":"Extractive Opinion Summarization in Quantized Transformer Spaces","first_author":"Stefanos Angelidis","url":null},"license":null,"modalities":[{"name":"Texts","url":"/datasets/modality/texts"}],"tasks":[{"name":"Unsupervised Opinion Summarization","url":"/task/unsupervised-opinion-summarization","datasets_with_task":"/datasets/task/unsupervised-opinion-summarization"}],"languages":[{"name":"English","url":"/datasets/language/english"}],"variants":["SPACE (Opinion Summarization)"],"data_loaders":[],"num_papers_in_archive":4,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/unsupervised-opinion-summarization-on-space","task":"Unsupervised Opinion Summarization","dataset_variant":"SPACE (Opinion Summarization)","rows":1,"metrics":["ROUGE-2","ROUGE-L"],"first_row_in_archive_order":{"model":"Hercules (abstractive)","paper":"/paper/attributable-and-scalable-opinion","metrics":{"ROUGE-2":"14.76","ROUGE-L":"27.22"},"code_links":[{"title":"tomhosking/hercules","url":"https://github.com/tomhosking/hercules"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/attributable-and-scalable-opinion","title":"Attributable and Scalable Opinion Summarization","date":"2023-05-19","rows_on_this_dataset":1,"code_links":1,"syntology":null}],"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."}
