{"url":"/dataset/3dssg","name":"3DSSG","full_name":null,"description_markdown":"3DSSG provides 3D semantic scene graphs for 3RScan. A semantic scene graph is defined by a set of tuples between nodes and edges where nodes represent specific 3D object instances in a 3D scan. Nodes are defined by its semantics, a hierarchy of classes as well as a set of attributes that describe the visual and physical appearance of the object instance and their affordances. The edges in our graphs are the semantic relationships (predicates) between the nodes such as `standing on, hanging on, more comfortable than` or `same material`.","description_withheld":null,"homepage":"https://3dssg.github.io/","introduced_date":"2020-04-08","introduced_date_note":null,"introduced_by":{"paper":"/paper/learning-3d-semantic-scene-graphs-from-3d","title":"Learning 3D Semantic Scene Graphs from 3D Indoor Reconstructions","first_author":"Johanna Wald","url":null},"license":null,"modalities":[],"tasks":[{"name":"Scene Graph Generation","url":"/task/scene-graph-generation","datasets_with_task":"/datasets/task/scene-graph-generation"},{"name":"3D Scene Graph Alignment","url":"/task/3d-scene-graph-alignment","datasets_with_task":"/datasets/task/3d-scene-graph-alignment"},{"name":"3d scene graph generation","url":"/task/3d-scene-graph-generation","datasets_with_task":"/datasets/task/3d-scene-graph-generation"}],"languages":[],"variants":["3DSSG"],"data_loaders":[],"num_papers_in_archive":36,"source":{"archive":"pwc-archive (Hugging Face), CC BY-SA 4.0","snapshot":"2025-07-28"},"benchmarks":[{"leaderboard":"/sota/3d-scene-graph-alignment-on-3dssg","task":"3D Scene Graph Alignment","dataset_variant":"3DSSG","rows":2,"metrics":["MRR","F1","Hits@1"],"first_row_in_archive_order":{"model":"SG-PGM","paper":"/paper/sg-pgm-partial-graph-matching-network-with","metrics":{"F1":"89.4","Hits@1":"97.5","MRR":"98.6"},"code_links":[{"title":"dfki-av/sg-pgm","url":"https://github.com/dfki-av/sg-pgm"}]},"note":"rows are the archive's own order at snapshot; nothing here re-ranks them"}],"papers_with_a_benchmark_row":[{"paper":"/paper/sg-pgm-partial-graph-matching-network-with","title":"SG-PGM: Partial Graph Matching Network with Semantic Geometric Fusion for 3D Scene Graph Alignment and Its Downstream Tasks","date":"2024-03-28","rows_on_this_dataset":1,"code_links":1,"syntology":null},{"paper":"/paper/sgaligner-3d-scene-alignment-with-scene","title":"SGAligner : 3D Scene Alignment with Scene Graphs","date":"2023-04-28","rows_on_this_dataset":1,"code_links":1,"syntology":{"read_at":"2026-09-24T18:15:14+00:00","samples_harvested":10,"samples_ran":7,"samples_unverified":3,"pointer_only_for_licence":0,"claim":"Per-sample execution on synthesized fixtures; not a correctness claim."}}],"syntology_totals":{"read_at":"2026-09-24T18:15:14+00:00","papers_with_samples":1,"samples_harvested":10,"samples_ran":7,"samples_unverified":3,"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."}
