1. George Thomas from the HHS OCIO discussed the health knowledge graph (GKG) which models relationships between things to help systems like Watson, Siri understand context. 2. He advocated for an open health knowledge graph to integrate health data from sources like healthdata.gov and link datasets. 3. The graph would use common schemas like schema.org and provide tools for users to edit, curate and link data.

“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
