Embodiment Construction

[0068] The solution provided by the present invention will be described below with reference to the accompanying drawings.

[0069] As mentioned above, using natural language for data query can greatly reduce the technical threshold of query data operation, so that query operators can easily query data without having to master a professional data query language. However, there are also problems in using natural language for data query at present. For data query and analysis based on natural language, for data extraction, the query statement obtained after language parsing is basically required to be completely accurate. This aspect is different from natural language processing algorithms in the field of traditional natural language processing (NLP), where the results of traditional natural language processing are usually probabilistic rather than completely accurate. Therefore, the current mainstream technical solutions for using natural language for data query (such as the s...

Abstract

The embodiment of this specification provides a data query method and device, the method includes: acquiring the first sentence used for data query of the data storage system, the first sentence is based on natural language; determining the natural semantics of the first sentence, the natural semantics Including the query condition on which the data query is based, and a description of the target data item that the data query is intended to obtain; based on natural semantics, a query logic tree is generated, and the query logic tree indicates an intermediate logical step for obtaining the target data item according to the query condition, Moreover, the intermediate logic steps have nothing to do with the data storage structure; according to the query logic tree, the second statement based on the data query language is generated.

Description

technical field [0001] One or more embodiments of this specification relate to the field of natural language processing and data analysis, and in particular, to a data query method and apparatus. Background technique [0002] Natural language query is a data query based on natural language. Natural language query reduces the technical threshold of data query operations, so that operators can easily query data without mastering a professional data query language. In particular, for example, in the case of insufficient number of professional and technical personnel who master the data query language in the enterprise, or in a scenario with a huge demand for data query, it can help enterprises to bottleneck the workload of data query due to the above reasons, and improve the efficiency of enterprise data query. However, the existing data query methods using natural language still have the problems that the query accuracy rate is still low and the support capability for complex...
