Abstract

The invention discloses a data query method supporting a natural language. The method comprises the following steps of receiving a natural language query statement of a user; establishing a natural language query statement based on the translation model, and translating and converting the natural language query statement into a target standard SQL statement; judging whether a target standard SQL statement can be obtained or not; if yes, outputting a data query result based on the target standard SQL statement; and if not, prompting the user to re-input other natural language query statements,and carrying out model training optimization on the translation model. By firstly decoding and translating natural language query statements into SQL statements, correctly marking the natural languagequery statements which cannot be translated and predicted by a translation model or have wrong translation, amplifying a model training sample set, and continuously training, an existing machine translation model is optimized for a natural language query system to call. On the other hand, the invention further provides a data query system supporting the natural language.

Description

technical field [0001] The invention relates to the technical field of data query, in particular to a data query method and system supporting natural language. Background technique [0002] With the extensive development and popularization of database applications and information retrieval systems, and the emergence and use of various intelligent portable information terminals, more and more non-professional users need an easy-to-grasp man-machine interface to access the required information. At present, most of the common forms are data reports based on windows and menus. Users only need to click with the mouse and a small amount of keyboard operations to obtain the required information from the database. But this method is not flexible and comprehensive enough, and many problems cannot or are difficult to express in this way. Another common way is to query the database through the standard SQL language. Although the SQL language is concise, clear and efficient, its langua...
