The present disclosure concerns automatically generating data retrieval queries. A system may include data residing on a first data store and a knowledge graph residing on a second data store. The knowledge graph may include a semantic model of the data. The knowledge graph may be structured differently than the data and may be stored in a format different from the data. The system may include a query builder that receives one or more inputs through a user interface. The user interface may be based in part on the knowledge graph. The one or more inputs may indicate a subset of the data. The query builder may retrieve metadata from the knowledge graph based on the one or more inputs. The query builder may then generate a query for retrieving the subset of the data using the one or more inputs and the metadata retrieved from the knowledge graph.
