Knowledge Graph Based Query Generation

摘要

Computer-implemented methods, systems and program storage devices for knowledge graph based query generation are disclosed herein. A computer-implemented method includes storing electronically a knowledge graph that represents relationships between a plurality of knowledge models. Further steps include: receiving a query specification that identifies a knowledge model for a query dataset; determining with a computing device a path based on path cost criteria, where the path covers a portion of the knowledge graph across one or more knowledge models to one or more data sources; and generating an initial query plan according to one or more knowledge models along the determined path to fulfill the query specification with data from one or more data sources.

1. A computer-implemented method for knowledge based query generation, comprising:
(a) storing electronically in memory a knowledge graph that represents relationships between a plurality of knowledge models; (b) receiving a query specification that identifies a knowledge model for a query dataset; (c) determining with a computing device a path based on path cost criteria, where the path covers a portion of the knowledge graph across one or more knowledge models to one or more data sources; and (d) generating an initial query plan according to the one or more knowledge models along the determined path to fulfill the query specification with data from the one or more data sources.
