This study presents a semantic approach to integrate health data from decentralized systems. It utilizes Semantic Web technologies like RDF and SKOS for better data interoperability in public health surveillance.

Area of Science:

  • Health Informatics
  • Semantic Web Technologies
  • Public Health Surveillance

Background:

  • Decentralized health information systems enable wider surveillance but often lack public health data utilization.
  • Representational and semantic heterogeneity challenges distributed health data integration.

Purpose of the Study:

  • To introduce a semantic approach for integrating health data from disparate sources.
  • To address challenges in public health use of decentralized health information systems data.

Main Methods:

  • Utilized Semantic Web technologies, specifically Resource Definition Framework (RDF).
  • Employed Simple Knowledge Organization System (SKOS) for knowledge organization.
  • Developed a semantic framework for health data integration.

Main Results:

  • Demonstrated a method for integrating health data across heterogeneous systems.
  • Facilitated improved data representation and semantic consistency.

Conclusions:

  • The proposed semantic approach enhances the integration of health data for public health applications.
  • Leveraging Semantic Web standards (RDF, SKOS) is effective for overcoming data heterogeneity in health surveillance.
