Design architecture for the Ontology based keyword search system. When the user wants to query the patient graph database to retrieve matching records, the only input necessary is the medical terms (q‐terms) and an indication to include any synonym, parent, or children terminology classes in the search. The software queries the Bioportal API and retrieves all the matching NCIT, SNOMED, ICD‐10 classes to the q‐terms. A SPARQL query is generated and executed on the graph database SPARQL endpoint and the results indicating the matching patient records and their corresponding data fields are displayed to the user. Our architecture includes the generation of text corpus from breath first search of individual patient graphs and using word embedding models to generate feature vectors to identify similar patient cohorts.
