Researchers have developed a new framework utilizing AI foundation models, specifically Large Language Models (LLMs) and Vision-Language Models (VLMs), to enhance semantic search and recommendation for documents containing spatial and temporal information. The framework introduces two novel algorithms: CAMERA, which combines textual and visual data for richer embeddings, and ASTRA, which refines ranking by considering scale-dependent spatiotemporal relevance alongside semantic similarity. Experiments using environmental event data showed that the VLM-enhanced methods significantly outperformed unimodal, LLM-based approaches, offering improved insights into localized environmental changes.
