Data query method and device

Abstract

The embodiment of the invention provides a data query method and device. The method comprises the steps of obtaining a first statement used for conducting data query on a data storage system, wherein the first statement is based on a natural language; determining the natural semantics of the first statement, wherein the natural semantics comprises a query condition of a data query basis and description of a target data item to be acquired for the data query; on the basis of natural semantics, generating a query logic tree, wherein the query logic tree indicates that an intermediate logic step of the target data item is obtained according to the query condition, and the intermediate logic step is irrelevant to the data storage structure; and generating a second statement based on the data query language according to the query logic tree.

Description

technical field

[0001] One or more embodiments of this specification relate to the fields of natural language processing and data analysis, and in particular, to a data query method and device. Background technique

[0002] Natural language query is data query based on natural language. Natural language query lowers the technical threshold of data query operation, so that operators can conveniently perform data query without mastering professional data query language. In particular, for example, in scenarios where the number of professional and technical personnel who master the data query language in the enterprise is insufficient, or the demand for data query is huge, it can help the enterprise to improve the efficiency of enterprise data query due to the bottleneck of data query workload caused by the above reasons. However, the existing data query methods using natural language still have the problems of low query accuracy and insufficient support for complex query oper...
