|a Recently, integrating vision and language for in-depth video understanding e.g., video captioning and video question answering, has become a promising direction for artificial intelligence. However, due to the complexity of video information, it is challenging to extract a video feature that can well represent multiple levels of concepts i.e., objects, actions and events. Meanwhile, content completeness and syntactic consistency play an important role in high-quality language-related video understanding. Motivated by these, we propose a novel framework, named Hierarchical Representation Network with Auxiliary Tasks (HRNAT), for learning multi-level representations and obtaining syntax-aware video captions. Specifically, the Cross-modality Matching Task enables the learning of hierarchical representation of videos, guided by the three-level representation of languages. The Syntax-guiding Task and the Vision-assist Task contribute to generating descriptions which are not only globally similar to the video content, but also syntax-consistent to the ground-truth description. The key components of our model are general and they can be readily applied to both video captioning and video question answering tasks. Performances for the above tasks on several benchmark datasets validate the effectiveness and superiority of our proposed method compared with the state-of-the-art methods. Codes and models are also released https://github.com/riesling00/HRNAT
