Multimodal Sentiment Analysis (MSA) focuses on leveraging multimodal signals for understanding human sentiment. Most of the existing works rely on superficial information, neglecting the incorporation of contextual world knowledge (e.g., background information derived from but beyond the given image and text pairs), thereby restricting their ability to achieve better multimodal sentiment analysis (MSA). In this paper, we propose a plug-in framework named WisdoM, to leverage the contextual world knowledge induced from the large vision-language models (LVLMs) for enhanced MSA. WisdoM utilizes LVLMs to comprehensively analyze both images and corresponding texts, simultaneously generating pertinent context. Besides, to reduce the noise in the context, we design a training-free contextual fusion mechanism. We evaluate our WisdoM in both the aspect-level and sentence-level MSA tasks on the Twitter2015, Twitter2017, and MSED datasets. Experiments on three MSA benchmarks upon several advanced LVLMs, show that our approach brings consistent and significant improvements (up to +6.3% F1 score).
