# Stanford I2V 600K

Frozen MTEB/MOEB representation of the official Stanford I2V 600K evaluation
release for image-to-video+audio retrieval.

## Construction

The dataset is reconstructed from Stanford Digital Repository record
[`zx935qw7203`](https://purl.stanford.edu/zx935qw7203), version
`15`. Query IDs, corpus paths, and relevance annotations
are preserved from `600k_dataset_queries_public.txt`,
`list_database_clips_600k_public.txt`, and `600k_dataset_public.txt`.
Multiple temporal annotations for the same query/video pair are collapsed to one
binary scene-level relevance judgment, matching the source scene-retrieval
protocol.

The construction script is maintained in the MTEB repository at
`scripts/data/stanford_i2v_retrieval/create_data.py`. Every source archive part is checked
against the size and MD5 digest in the Stanford record before extraction. Images
are decoded, videos are probed for a valid video stream, and their AAC soundtracks
are placed in a separate audio column and fully decoded with strict error handling.
Soundtracks with valid AAC streams are losslessly remuxed. The
81 tracks containing malformed source packets are
decoded and re-encoded while preserving timestamp gaps. One of those tracks has
an unrecoverable first 69 seconds, which are replaced with silence; its only
relevance annotation (2:25-2:27) lies in the recoverable suffix.

## Frozen evaluation contents

- Queries: 229 (official: 229)
- Corpus video+audio clips: 3401 (official: 3401)
- Binary query/video qrels: 1280 (official: 1280)
- Source temporal annotations: 2260
- Distinct positive corpus videos: 1188 (official: 1188)
- Distractor corpus videos: 2213 (official: 2213)
- Missing or corrupt queries: 0
- Missing or corrupt videos: 0
- Missing or corrupt audio tracks: 0
- Re-encoded source-malformed audio tracks: 81
- Tracks with an unrecoverable prefix replaced by silence: 1
- Queries removed because no positive survived: 0

Configs follow MTEB's standard retrieval representation: `queries`, `corpus`,
and `qrels`, each with a `test` split.

## Evaluation

The source benchmark reports mean average precision over the top 100 retrieved
scenes. The corresponding MTEB primary metric is `map_at_100`. Stanford's scorer
divides each query's precision sum by the total number of relevant corpus videos,
which matches standard truncated AP@100 for this release.

## Comparability with the 2015 paper

The 600K query and ground-truth manifests are byte-identical to the full release:
all 229 queries and all annotated positive videos are preserved. The corpus is
the official 3,401-video 600K corpus rather than the 84,443-video full corpus used
for the principal 2015 paper results. The query set, qrels, and metric are
therefore identical, but scores are not directly comparable because the 600K
release contains fewer distractor videos. The 600K release was documented in the
later Bloom-filter retrieval paper.

## Licensing and provenance

The Stanford source record provides public download access but does not specify a
dataset-wide license. Accordingly, this repository records the license as **not
specified** and does not claim that the source media is under an open license.
Query images originate from news websites and corpus videos are recorded
newscasts; rights may remain with their respective owners. Users are responsible
for confirming that their use complies with applicable source terms and law.
