Abstract
A method for querying and analyzing datasets via natural language processing (NLP) with context propagation is disclosed. In one embodiment, a computer-implemented method includes receiving, by a user interface, at least one of an utterance or a structured query language statement. The method includes identifying zero or more previous data conversation steps indicated by the utterance. The method includes determining an effective schema targeted by the utterance. The method includes generating, based on the utterance and the effective schema, an intermediate structured query language statement that is representative of the utterance. The method includes generating an executable structured query language statement based on the intermediate structured query language statement and zero or more previous structured query language statements. The method includes executing the executable structured query language statement for the data query engine schema. The method includes communicating, via the user interface, a result set and metadata.
