Embodiment Construction

[0029]The technical solutions of the present application will be clearly and completely described below in conjunction with the embodiments. Apparently, the described embodiments are part of the embodiments of the present application, not all of them. Based on the embodiments in this application, all other embodiments obtained by persons of ordinary skill in the art without making creative efforts belong to the scope of protection of this application.

[0030] In the process of information search based on natural language input by users, the existing processing idea is often to establish a mapping relationship directly from pure natural language to database (such as: SQL) execution language through a certain algorithm, through which the mapping relationship is Natural language can be directly converted into database execution language to complete information search. However, this method only requires one conversion process, which often has the problem of insufficient conversio...

Abstract

The invention provides a natural language query statement processing method and device and electronic equipment. The method comprises the steps of obtaining a natural language query statement of a user; according to a preset data table and a preset keyword table, performing target word extraction and identifier labeling on the natural language query statement to obtain a target word combination, namely a plurality of target words and attribute identifiers and position identifiers corresponding to the target words; according to the attribute identifiers and the position identifiers corresponding to the multiple target words, performing text reconstruction on the multiple target words by utilizing a target text reconstruction rule corresponding to the target word combination to obtain a target query statement; and converting the target query statement into a database execution language so as to carry out information query. According to the method and device, the natural language query statement of the user can be converted into the target query statement through the target word extraction and the rule-based text reconstruction process, then the target query statement is converted into the database execution language, and the accuracy of information query can be greatly improved through two times of conversion.

Description

technical field [0001] The present application relates to the technical field of natural language processing, in particular to a natural language processing method, device and electronic equipment. Background technique [0002] In the process of information search based on natural language input by users, the existing processing idea is often to establish a mapping relationship directly from pure natural language to database (such as: SQL) execution language through a certain algorithm, through which the mapping relationship is Natural language can be directly converted into database execution language to complete information search. However, this method only requires one conversion process, which often has the problem of insufficient conversion accuracy, which may lead to deviations in the converted database execution language, which in turn leads to inaccurate information search results. Contents of the invention [0003] The purpose of this application is to provide a ...
