US Patent 10007879 Authoring system for assembling clinical knowledge

Ranking of data and retrieval of data or relationships of the data responsive to the ranking. A data model is represented as a graph, with edges in the graph linking related concepts, and an assertion represented in the graph as a reified n-ary relation. The graph is ingested though traversal and storage of the node paths. The traversal includes concepts and categories. In addition, neighborhood of one or more adjacent concepts are followed and stored in relation to the node paths. The ingested graph is converted into a set of flat document structures supported by information ranking and a retrieval framework.
