Towards Holistic Language-video Representation: the language model-enhanced MSR-Video to Text Dataset

원문 초록

A more robust and holistic language-video representation is the key to pushing video understanding forward. Despite the improvement in training strategies, the quality of the language-video dataset is less attention to. The current plain and simple text descriptions and the visual-only focus for the language-video tasks result in a limited capacity in real-world natural language video retrieval tasks where queries are much more complex. This paper introduces a method to automatically enhance video-language datasets, making them more modality and context-aware for more sophisticated representation learning needs, hence helping all downstream tasks. Our multifaceted video captioning method captures entities, actions, speech transcripts, aesthetics, and emotional cues, providing detailed and correlating information from the text side to the video side for training. We also develop an agent-like strategy using language models to generate high-quality, factual textual descriptions, reducing human intervention and enabling scalability. The method's effectiveness in improving language-video representation is evaluated through text-video retrieval using the MSR-VTT dataset and several multi-modal retrieval models.
