TraceCIR / RevCIR

A multi-turn revision-layer Composed Image Retrieval (CIR) benchmark over fashion. Each chain is a shopper iteratively editing an image search (POS / NEG / MIXED / COMMIT→RETRACT / cross-category turns), with per-turn query forms (rule tag-diff, FashionIQ-style terse, and a persona-styled rich utterance).

Data is hosted on HuggingFace (private): fashiontrace/tracecir (request access; then huggingface-cli login).

Current renderer version = v4 (multi-turn rebuild, all chains ≥3 turns). The releases/latest/ path always points at the version the viewer currently renders:

# full set / splits (jsonl, one chain per line)
huggingface-cli download fashiontrace/tracecir releases/latest/tracecir.jsonl      --repo-type dataset --local-dir .
huggingface-cli download fashiontrace/tracecir releases/latest/tracecir.val.jsonl  --repo-type dataset --local-dir .
huggingface-cli download fashiontrace/tracecir releases/latest/tracecir.test.jsonl --repo-type dataset --local-dir .

Images are a single shared pool, archived as images_pool.tar in the repo root (~3.59 GB, 142,704 images; covers every release version v1–v4). This full pool is the retrieval gallery for eval; only 9,768 distinct images appear in the 2,988 chains, so the gallery is ~15× the referenced set (what makes Recall@k meaningful). Download + extract once:

huggingface-cli download fashiontrace/tracecir images_pool.tar --repo-type dataset --local-dir .
tar xf images_pool.tar          # -> images/<category>/<image_id>.jpg

Image id in the jsonl = the filename stem (e.g. fashion200k_dress_00123 or a FashionIQ id).

Versions

• v4 (releases/v4/, current): multi-turn rebuild — 2988 chains, category-balanced (498/cat×6), all ≥3 turns (~82% ≥4 turns), persona-styled rich queries per turn. Judged consistently by Qwen3.6-35B-A3B (thinking); failed turns recovered by re-judge + salvage (image-grounded edit re-derivation). val 1470 / test 1518.
• v3 = data/revcir_balanced.json (2982 chains, 75% 2-turn). v1/v2 text = versions/.
