MCG-NJU/VideoChat3-Academic2M
收藏资源简介:
VideoChat3-Academic2M是VideoChat3使用的学术视频指令数据。它通过对公开学术视频数据集进行重新注释,用于视频字幕生成、视频问答和细粒度运动理解。该数据集遵循基于证据的注释增强流程,将简短答案、仅选项标签和简洁字幕重写为更丰富的指令跟随响应,这些响应提及可见对象、动作、场景、时间线索和支持证据。然后通过一致性过滤阶段,确保重写注释与原始学术标签保持一致。
VideoChat3-Academic2M is the academic video instruction data used by VideoChat3. It re-annotates public academic video datasets for video captioning, video question answering, and fine-grained motion understanding. The dataset follows an evidence-grounded annotation enhancement pipeline. Short answers, option-only labels, and concise captions are rewritten into richer instruction-following responses that mention visible objects, actions, scenes, temporal cues, and supporting evidence. A consistency filtering stage is then used to keep rewritten annotations aligned with the original academic labels.
