Natural language querying of a data lake using contextualized knowledge bases

摘要

A method of querying a data lake using natural language includes: receiving a natural language query directed to an electronic data lake; parsing the natural language query to determine a plurality of entities within the natural language query; identifying the plurality of entities using at least one contextual knowledge base, wherein the plurality of entities are compared against at least one entry in the at least one contextual knowledge base; mapping a dependency of the plurality of identified entities based on the parsed natural language query; constructing a structured data query based on the plurality of identified entities and the mapped dependency; and automatically generating a visual output of a result of the structured data query based on at least one characteristic from the set of: a data type, a data format, and a data size of the result of the structured data query.
