AIDAVA
AI-powered Data Curation & Publishing Virtual Assistant. EU Horizon Europe research project automating curation and publishing of personal health data using AI.
AIDAVA prototypes and tests an AI-powered virtual assistant that maximizes automation of data curation and publishing of unstructured and structured, heterogeneous health data. The assistant includes a backend library of AI-based data curation tools and a frontend based on human-AI interaction modules.[1]

"Curate once, reuse many times" — supporting patients, clinical care providers and clinical researchers from the same curated data.[2]
The project addresses the core problem that integrated, high-quality personal health data represents a potential wealth of knowledge for healthcare systems, but there is no reliable conduit for this data to become interoperable, AI-ready and reuse-ready at scale.[3]
Technology Pillars
- Automation of quality enhancement and FAIRification of collected health data, in compliance with EU data privacy
- Knowledge graphs with ontology-based standards as universal representation — each Personal Health Knowledge Graph (PHKG) is an instance of a common reference knowledge graph based on ontologies derived from SNOMED, HL7 FHIR resource profiles, LOINC, and other domain-specific terminologies[4]
- Deep learning for information extraction from narrative content — NLP developed in three languages
- AI-generated explanations during the process to increase users' confidence (explainability)[5]
Use Cases
- Breast cancer patient registries — structured registry data curation across 3 university hospitals
- Longitudinal health records for cardiovascular patients — integrating heterogeneous data sources over time
Both tested in three languages (Dutch, German, Estonian) with hospitals and emerging personal data intermediaries.[6]
Evaluation Results (from March 2025 Flash)
- 83 patients recruited; 70 completed evaluation
- G1 prototype (June 2024) tested in Estonia, Austria, Netherlands
- 45% of documents curated automatically
- Average 20 minutes per document (too slow)
- Usability good, but explanations suboptimal and benefits unclear
- G2 delivery: end 2025, testing early 2026
- Project end: August 2026
