  1. healthdata.govnow and next challenges overview hhsocio, health datapalooza 2012

  2. session agenda • now • tools and features • next • target architecture • challenges • explanations in sequence

  3. now – tools and features • Drupal • publishing workflow and community engagement • Solr • faceted search • CKAN • ‘on demand resources’ (RESTful API and feeds) • EC2 • powered by GovCloud • github.com/hhs • public repo’s coming soon!

  4. publishing workbench • insert interesting workbench screenshot

  5. community engagement • insert interesting community engagement screenshot • question and/or ideas example

  6. faceted search

  7. hub.healthdata.gov/api/rest/dataset step 1: HTTP GET /dataset collection as JSON (GUID or name)

  8. hub.healthdata.gov/api/rest/dataset/{name} step 2: HTTP GET each /dataset (as JSON, RDF/XML, or N3)

  9. hub.healthdata.gov/api/search/dataset?q=medicare+costs JSON results for ‘medicare’and ‘costs’ search query

  10. hub.healthdata.gov/feeds/dataset.atom atom feed for all datasets (including recent updates and changes)

  11. hub.healthdata.gov/feeds/custom.atom?q=medicare+cost custom search query result atom feed (anything with ‘medicare+cost’)

  12. next – target architecture • linked data • (closed) google knowledge graph • open health knowledge graph • integration framework • top down modeling • bottom up mapping • social curation

  13. #gkg – (closed) ‘things, not strings’ “The Knowledge Graph helps us understand the relationships between things [… that are] linked in our graph. […] It’s not just a catalog of objects; it also models all these inter-relationships.” source

  14. open health knowledge graph

  15. health.data.gov/id/hospital/393303

  16. clinical quality linked data (HDI II)

  17. lifting and enrichment

  18. Linked Data Integration Framework GKG/Watson/Siri/… healthdata.gov PCAST DEAS HKG Variety Volume Velocity Health Data Actor

  19. social meta/data – graph curation

  20. i2 challenges • two types • three domain specific • improve the integration and liquidity of data made available • four platform specific • enhance the capabilities of the technology components • 3 release rounds • sequenced to leverage dependencies • round 1: June through October 2102 • round 2: November 2012 through May 2013 • round 3: June through December 2013

  21. round 1 challenges • June 2012 through October 2012 • domain specific • [1.1] cross domain and domain specific metadata • voluntary consensus standards organizations, defacto standards, other • platform specific • [1.2] Simplified Sign On (SSO) • WebIDidentity provider and relying parties, HDP infrastructure components • $35K: $20K 1st, $10K 2nd, $5K 3rdplace prizes

  22. round 2 challenges • November 2012 through May 2013 • domain specific • [2.3] Mapping, Reconciliation and Correlation • structural variety, authoritative URI’s, linking heuristics • platform specific • [2.4] Faceted Browsing and Visualization • D3 (backbone, jQuery, etc.) • [2.5] Custom API • Linked Data API ‘configurator’ for dataset resources • each of these builds on [1.1] results

  23. round 3 challenges • June 2013 through December 2013 • domain specific • [3.6] Correlating HHS and NHS Classifications • structural variety, authoritative URI’s, linking heuristics • platform specific • [3.7] Linked Data API based Data Element Access Services • ‘securing the data, not just the device’ • builds on [1.1], [1.2], and [2.5]

  24. domain challenge [1.1] • 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. • 374 on challenge.gov

  25. W3C SKOS – concept schemes

  26. W3C DCAT – data catalogs

  27. hub.healthdata.gov/dataset/hospice-medicare-cost-report-data.rdfhub.healthdata.gov/dataset/hospice-medicare-cost-report-data.rdf rdf/xml output uses dublin core and dcat metadata (mapping issues to work out, N3 output is incomplete, etc.)

  28. https://github.com/HHS/hd2-ckan/blob/master/templates/package/read.rdfhttps://github.com/HHS/hd2-ckan/blob/master/templates/package/read.rdf ckan script that creates dc and dcat metadata tags / values (thanks @JoshData! public github repo soon :-)

  29. W3C Data Cube – statistics refactor CQLD vocabs/data? start here and follow imports

  30. W3C Provenance – change mgmt apply to CKAN /revisions

  31. hub.healthdata.gov/revision

  32. W3C org – organization

  33. quantity, units, dimensions, time

  34. OGC GeoSPARQL – geospatial

  35. OMG BMM – business motivation image source

  36. CQLD domain specific

  37. platform challenge [1.2] • WebIDbased SSO • will improve community engagement • by providing simplified sign on (SSO) for external users interacting across multiple HDP technology components, • making it easier for community collaborators to contribute, • leveraging new approaches to decentralized authentication. • 375 on challenge.gov

  38. relying party WebID login

  39. identity provider WebID login

  40. edit WebID property ACL at IdP

  41. property is now visible to the RP

  42. domain challenge [2.3] • Mapping, Reconciliation and Correlation • builds on the Metadata domain challenge [1.1] • 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.

  43. automating structural transformations

  44. ‘reconciling’ strings to things

  45. result: turtle is the new JSON!

  46. link automation heuristics editor

  47. platform challenge [2.4] • Faceted Browsing and Visualization • builds on the Metadata domain challenge [1.1] • uses the most popular browser based UI frameworks and libraries to realize novel exploration and discovery techniques for traversing large amounts of interrelated data, • contributing to a growing collection of open source widgets that make it easy for third parties to create new applications and embed health data in their content.

  48. surfing the domain schemata no domain knowledge required to discover entities and relationships

  49. agents construct e/r queries Siri, which {LA County} Hospitals have the best {Heart Attack} stats?

  50. d3 (jQuery, backbone, etc.)
