When One Moment Isn't Enough: Multi-Moment Retrieval with Cross-Moment Interactions

Existing Moment retrieval (MR) methods focus on Single-Moment Retrieval (SMR). However, one query can correspond to multiple relevant moments in real-world applications. This makes the existing datasets and methods insufficient for video temporal grounding. By revisiting the gap between current MR tasks and real-world applications, we introduce a high-quality datasets called QVHighlights Multi-Moment Dataset (QV-M2), along with new evaluation metrics tailored for multi-moment retrieval (MMR). QV-M2 consists of 2,212 annotations covering 6,384 video segments.
