ScanQA Test w/ objects Benchmark (3D Question Answering (3D-QA))
A 3D-QA task requires models to answer a question when given all the information of a 3D scene. Here, models use the 3D spatial information, such as RGB-D scans or point cloud data. We also require models to specify the 3D-bounding boxes of objects that are related to this question answering. This prevents models from answering questions by relying on the textual priors of the trained questions without examining the scene. However, unlike 3D dense captioning, we do not require models to target one described object for each question. This is because multiple objects can be used to answer certain questions. For example, the question “What color is the chairs around the table?” is related to multiple objects. This question is also answerable as long as the chairs around the unique table in the scene have the same color. In such scenarios, we require models to answer the question addressing multiple 3D-bounding boxes.

The chart needs JavaScript; the table below carries every value.
Direction inferred from the metric name, not from the archive: BLEU-1 (higher is better), BLEU-4 (higher is better), ROUGE (higher is better). Not inferred (points only, no best-so-far line): Exact Match, METEOR, CIDEr. Points are placed at the row's paper date; 18 of 18 rows carry one.
Results archive 2025-07-28
Archive rows end at the archive snapshot, 2025-07-28: no result published after that date is in this table. Rank is the archive's row order at that snapshot; not re-ranked here. Metric values are the archive's strings. Column headers sort the table in your browser; each row keeps its archive rank.

Syntology Ran reads "N of M ran · U unverified": of the M code samples Syntology harvested from repositories linked to that row's paper (joined by arXiv id), N executed on a synthesized input and the other U = M−N are unverified (harvested, no recorded run). It counts code from repositories linked to that row's paper, not this result: the row's number was not reproduced and nothing here is a correctness claim. The other cell texts mean no graph line for the row: "linked, not harvested" (the archive links code, Syntology has not harvested it), "no code linked" (no code link in the archive), "not matched" (the row's paper URL matched no paper on this site). 11 rows have a graph line, from 8 distinct papers; 11 rows (8 papers) have at least one sample that ran. Counting each paper once: Syntology ran 67 of 129 samples; 62 unverified. Separately, 28 of those 129 are pointer-only (licence): the site points at that code rather than redistributing it, a licence property recorded for ran and unverified samples alike; each cell's tooltip carries the row's own pointer-only count.
