  • 1. Open Health Knowledge Graphs#hdpalooza 2013Technical Development Track6/3, 1:30-2pm, Congressional RoomGeorge Thomas, HHS OCIO
  • 2. 1agenda (as advertised)1. This session introduces the business value of Linked Data,demonstrating how Linked Data enables the network effectthrough a process of „collaboration without coordination,‟resulting in the integration of information systems acrossdisparate open government data publishers.2. This session will describe healthdata.govplatform components, including new functionality thatprogrammatically exposes tabular and graph-oriented data.3. We will set the context for follow-up sessions that reviewrecent winning submissions for developer challenges and afinal panel discussion about technical opportunities andupcoming developer challenges contributing to thematuration of healthdata.gov as a useful knowledge graph.

  • 10. 93.1 first domain developer challenge• Metadata– requests the application of existing voluntaryconsensus standards for metadata common to allopen government data– and invites new designs for health domain specificmetadata to classify datasets in our growing catalog,creating entities, attributes and relations– that form the foundations for better discovery,integration and liquidity.• results page
  • 11. 103.2 second domain developer challenge• Mapping, Reconciliation and Correlation– builds on the Metadata domain challenge– begins by acknowledging disparate open government publishingpractices– and seeks the demonstration of an innovative and automatedsolution for transforming semi-structured data into structured data,– reconciles decentralized distributions about the same data entityagainst the master identity of an authoritative source,– and correlates these master identities when multiple authoritativesources exist,– enabling the network effect by introducing strong identity resolutiontechniques that ease the ability to aggregate different data aboutthe same entities from independent publishers.
