AI-powered Data Curation & Publishing Virtual Assistant. EU Horizon Europe research project automating curation and publishing of personal health data using AI.

Overview

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]

Vision

"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 across institutions, at national and EU level.[3]

Technology Pillars

  1. Automation of quality enhancement and FAIRification of collected health data, in compliance with EU data privacy
  2. 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]
  3. Deep learning for information extraction from narrative content — NLP developed in three languages
  4. AI-generated explanations during the process to increase users' confidence (explainability)[5]

Use Cases

  1. Breast cancer patient registries — structured registry data curation
  2. Longitudinal health records for cardiovascular patients — integrating heterogeneous data sources over time

Both tested in three languages with hospitals and emerging personal data intermediaries.[6]

Solution Architecture

  • Data cleaning machine — orchestrating multiple AI-based tools to automate curation
  • Personal Health Knowledge Graph (PHKG) — universal semantic representation of all personal health data
  • Conversational AI assistant — engages patients, with explainability capabilities
  • Metadata capture — on data sources to support automation within a formalised Data Transfer Specification
  • Tools orchestrated include: OCR, syntactic transformation, semantic transformation, entity deduplication, NLP, feature extraction from imaging[7]

Impact

  • Decrease workload of clinical data stewards through increased automation
  • Improve effectiveness of clinical care through high-quality data
  • Support clinical research with reusable, interoperable data
  • Long-term: democratise participation in data curation by citizens/patients
  • Support delivery of the European Health Data Space (EHDS)[8]
