DataTools4Heart_Milestone MS15: AI-powered Virtual Assistants (VAs) supporting multilingual interaction in at least 7 languages built, demonstrated, and released

MS15 has been achieved. The DataTools4Heart (DT4H) Virtual Assistant has been integrated into the DT4H platform, demonstrated to relevant stakeholder groups, and released as an operational component supporting multilingual interaction in seven languages: English, Spanish, Swedish, Dutch, Italian, Romanian, and Czech. The VA enables natural-language access to the Data Catalogue and supports privacy-preserving retrieval of aggregated cohort metadata through FEM/SMPC, while operating within the platform’s secure authentication and access-control framework. The milestone outcome was validated through repeated demonstrations to clinicians, researchers, AI developers, technical partners, and ethics/legal experts during consortium meetings. MS15 is further evidenced by Deliverable D6.1, which provides demonstrator material for the platform and the AI-powered Virtual Assistant.
