Open Health Knowledge Graphs Moderator: George Thomas, Enterprise Architect, Office of the Chief Information Officer (CIO), U.S. Department of Health & Human Services This session introduces the business value of Linked Data, demonstrating how Linked Data enables the network effect through a process of ‘collaboration without coordination,’ resulting in the integration of information systems across disparate open government data publishers. This session will describe healthdata.gov platform components, including new functionality that programmatically exposes tabular and graph-oriented data. We will set the context for follow-up sessions that review recent winning submissions for developer challenges and a final panel discussion about technical opportunities and upcoming developer challenges contributing to the maturation of healthdata.gov as a useful knowledge graph.

3.1 first domain developer challenge
• Metadata
– requests the application of existing voluntary
consensus standards for metadata common to all
open government data
– and invites new designs for health domain specific
metadata to classify datasets in our growing catalog,
creating entities, attributes and relations
– that form the foundations for better discovery,
integration and liquidity.

3.2 second domain developer challenge
• Mapping, Reconciliation and Correlation
– builds on the Metadata domain challenge
– begins by acknowledging disparate open government publishing
practices
– and seeks the demonstration of an innovative and automated
solution for transforming semi-structured data into structured data,
– reconciles decentralized distributions about the same data entity
against the master identity of an authoritative source,
– and correlates these master identities when multiple authoritative
sources exist,
– enabling the network effect by introducing strong identity resolution
techniques that ease the ability to aggregate different data about
the same entities from independent publishers.
