Researchers have introduced V-STORM, a novel framework designed to enhance spatio-temporal reasoning in Multimodal Large Language Models (MLLMs). This framework converts videos into Spatio-Temporal Scene Graphs (STSGs) and derives Grounded Chain of Thought (GCoT) annotations from validated evidence paths, making each reasoning step traceable. A dataset of 260,000 samples and a 3,000-sample benchmark have been constructed using this method, revealing that while current MLLMs can identify relevant spatio-temporal cues, they struggle to integrate them into multi-step reasoning. Fine-tuning with V-STORM has shown significant improvements in both answer accuracy and grounding faithfulness. AI
