From Data Streams to User Screens: a Multimodal hEalth Datawarehouse for ITAly (MEDITA). 

Abstract : 

Public health data are essential for understanding population health, monitoring trends, and informing evidence-based decision-making. Data Warehouses (DWs) play a critical role in standard­ izing, integrating, and analyzing large-scale datasets. However, existing solutions often encounter challenges such as data fragmentation, structural complexity, and limited user interactivity. This paper presents MEDITA (Multimodal hEalth Datawarehouse for ITAiy), a prototype platform de­ signed to unify and analyze both textual and tabular data from Italian public health sources through an Extract-Transform-Load-Model-Deploy (ETLMD) pipeline. MEDITA includes interactive visu­ alization tools, statistical modeling for time series analysis, and a Retrieval-Augmented Generation (RAG) chatbot that enables real-time querying in Italian. As a centralized and user-friendly reposi­ tory, MEDITA enhances accessibility for both healthcare researchers, who require structured data for analysis, and the general public, who can explore public health insights without technical expertise. Future development may include support for video, audio, and electronic health records, expanding the role of multimodal analytics in public health research.
