NODES 2022

HealthECCO will be speaking at NODES 2022:
The HealthECCO Knowledge Graph: Applying Neo4j Technologies in Health Data Research
Description

Health data, in general, is often siloed and inaccessible. The FAIR data principles have contributed to overcome this situation and make health data more findable, accessible, interoperable, and reusable – but mostly within their very specific data domains.
Using the examples of COVID-19 data and data from health studies in epidemiology provided by the NFDI4health study hub, researchers at University Medicine Greifswald will showcase how a knowledge graph integrates multiple open data sources using a Neo4j graph database. It connects previously disparate data domains, and then offers specific interfaces for data access and exploration.

The focus of this talk will be on introducing the main code repositories included in the HealthECCO graph, explaining the workflow behind the data loading pipeline, and showcasing the use of Neo4j for health data exploration. Whenever a new data source should be added, the pipeline can be modified to integrate the (fully annotated) dataset.
