Scene graph generation (SGG) aims to parse a visual scene into an intermediate graph representation for downstream reasoning tasks.Despite recent advancements, existing methods struggle to generate scene graphs with novel visual relation concepts.To address this challenge, we introduce a new open-vocabulary SGG framework based on sequence generation.Our framework leverages vision-language pre-trained models (VLM) by incorporating an image-to-graph generation paradigm.Specifically, we generate scene graph sequences via image-to-text generation with VLM and then construct scene graphs from these sequences.By doing so, we harness the strong capabilities of VLM for open-vocabulary SGG and seamlessly integrate explicit relational modeling for enhancing the VL tasks.Experimental results demonstrate that our design not only achieves superior performance with an open vocabulary but also enhances downstream vision-language task performance through explicit relation modeling knowledge.
