It contains 2,700 simulation videos from 27 physics families. The family shards are loaded together as the default configuration. ## Usage ```python from datasets import load_dataset dataset = load_dataset( "World-Representation-Lab/World-Embedding-Optics-Retrieval", split="test", ) ``` ## Fields - `query_id`: unique text-query identifier. - `case_id`: simulation case identifier. - `raw_text`: structured physical description. - `parsed_text`: natural-language retrieval caption. - `video`: simulation video. The benchmark uses `parsed_text` for text-video retrieval. ## Citation ```bibtex @misc{liu2026worldembeddingbenchmark, title = {World Embedding Benchmark}, author = {Yiqi Liu and Ruifeng Yuan and Yang Wang and Long Li and Fengyu Cai and Hou Pong Chan and Jialin Yu and Hao Zhang and Chenghua Lin and Chenghao Xiao}, year = {2026}, eprint = {2610.03632}, archivePrefix = {arXiv}, primaryClass = {cs.CV}, url = {https://arxiv.org/abs/2610.03632} } ```
