Researchers have introduced IAE-VTG, a novel approach to Video Temporal Grounding (VTG) that specifically addresses queries involving actions performed by entities. Unlike previous methods that treat queries holistically, IAE-VTG disentangles action and entity information within the query to better align with complementary video features. This is achieved through a Fine-grained Disentangled Interaction Module (FDIM) and an Interaction-Sensitive Assignment (ISA) training strategy, which improves the accuracy of temporal localization by considering both temporal overlap and semantic compatibility. Experiments on benchmark datasets like QVHighlights, Charades-STA, and TACoS demonstrate that IAE-VTG enhances existing baselines and achieves competitive or state-of-the-art results, particularly for complex events with repeated actions or entities.
