# VideoGLaMM ActivityNet Entities GCG — object text review, 20 samples

Independent review Space; the reference VIPOSeg Space is unchanged. Layout adapted from [VIPOSeg Grounded Caption Review](https://huggingface.co/spaces/Viviannnyang/VIPOSeg_Grounded_Caption_Review).

20 distinct original ActivityNet video IDs, one randomly selected eligible segment per video (seed 20261030). The supplied media are 10 sampled RGB frames per segment, not complete videos. The source masks/bounding boxes are supplied on one reference frame only. No mask propagation or new segmentation was performed. Frame time labels are estimates from the source sampling procedure; original video FPS is unknown. Playback is a slideshow at a user-facing inspection rate, not original speed.

Uses the exact words of `refined_caption` after stripping source phrase/SEG markup and normalizing whitespace. Original `refined_caption`, `new_caption`, original JSON, model JSON, derived spans, and mask provenance remain available. All text groups are retained, including groups without masks.

All 20 OpenAI Batch requests completed, with no API/parse failures. GPT saw 10 clean RGB frames plus the all-mask ID overlay, identity sheet, and binary-mask sheet for each sample. 107 entity groups and 188 mentions, 32 source masks. Model candidates: 24 matched, 52 missing mask, 21 not visible in reference, 7 mask quality issue, 2 ambiguous, 1 requires mask union. No complete correspondence candidates; no human-reviewed samples in the immutable source data. Structural validation does not prove semantic correctness or full entity coverage.

The provided annotation guideline is preserved verbatim in `data/TEXT_ANNOTATION.original.md` and embedded in `data/annotation_prompt.txt`. Source example inconsistencies and approved execution notes are recorded separately. Original annotation rule SHA256: d6ebb95f5bc1912569660ddf7622329204c71245050d044813e52ac21d425ac6.

Review status and notes are saved only in this browser (versioned localStorage key `videoglamm-activitynet-object20-review-v1`). They do not change original data or create shared server annotations. Export/import JSON to move reviews between browsers or send them for aggregation. Exports bind to the immutable dataset SHA256. A review mark does not make missing masks complete.
