+- Dataset card refresh based on Slack review feedback:
+  - **Tasks and Submission Formats** table: Single Object Tracking now categorized as `Spatio-Temporal`. Metric updates: `2D Object Localization → F1@0.5`, `2D Referring Expressions → mIoU`, `Single Object Tracking → AUC`. The per-task submission-format column has been removed; expected formats and the leaderboard will be published soon.
+  - **Metric Notes** refreshed: added `mIoU`, `F1@0.5`, `AUC`; dropped `mAP@IoU`, `Acc@IoU`, `HOTA`.
+  - **Dataset Quantification** table: `Videos` column renamed to `Media`. Per-task counts updated. Totals now report `Total Entries (Annotations): 35,027` and `Total Media Samples (across tasks, with overlaps): 3,346`.
+  - **Evaluation Server** description: clarified that the GitHub repo is a sample evaluation pipeline. Predictions are submitted to the official leaderboard, live by end of May 2026.
+  - **Task overview figure** in References now renders full-width via inline HTML `<img width="100%">`.

 ### Metric Notes

 - **SODA-c**: Metric for dense video captioning quality across event coverage and language quality.
 - **mAP@tIoU**: Mean Average Precision measured over temporal IoU thresholds.
 - **F1 Score**: Harmonic mean of precision and recall.
-- **mAP@IoU**: Mean Average Precision measured over spatial IoU thresholds.
-- **Acc@IoU**: Correct grounding if predicted box overlaps target above IoU threshold.
+- **F1@0.5**: F1 score at an IoU threshold of 0.5.
+- **mIoU**: Mean Intersection over Union — average overlap between predicted and ground-truth bounding boxes.
 - **Pointing Accuracy**: Percentage of correctly selected target regions.
-- **HOTA**: Higher Order Tracking Accuracy, combining detection and association quality.
+- **AUC**: Area under the ROC curve, measuring the model's ability to distinguish correct detections or tracks from incorrect ones across varying confidence thresholds.
 
 ### Evaluation Server
 
-Predictions are submitted to the evaluation server hosted on HuggingFace. The server computes metrics against held-out annotations and updates the public leaderboard.

-Evaluation server: [VANTAGE-Bench](https://github.com/anon-benchmark/VANTAGE-bench)
+The [VANTAGE-Bench GitHub repository](https://github.com/anon-benchmark/VANTAGE-bench) provides a sample evaluation pipeline for generating model predictions. Predictions are submitted to the official leaderboard, which will go live by the end of May 2026.
