Abstract

The invention discloses a table-based question and answer method and system. The method comprises the following steps: constructing a first SQL query statement according to an input problem of a natural language and predefined table metadata; updating the first SQL query statement according to the historical context information to obtain a second SQL query statement; executing the second SQL query statement to obtain a query result; and constructing a response of the input question according to a query result of the second SQL query statement. Due to the fact that the second SQL query statement is combined with the historically executed SQL query statement and the execution result thereof, the query result of the second SQL query statement is more comprehensive and accurate, the real intention of the user is hit more possibly, questions of the user are reduced, the interaction efficiency between the system and the user is improved, and the user experience is improved.

Description

technical field [0001] The present disclosure relates to the field of computer technology, and in particular, to a table-based question answering method and a systematic method. Background technique [0002] With the development of computer technology, more and more users obtain the required information through the Internet, such as online inquiries about ticketing, catering, etc. In order to save labor costs and improve service efficiency, intelligent question answering systems have been used in these scenarios. In the prior art, the intelligent question answering system can design tables and table data in advance, and limit the questions input by the user to the range corresponding to the table data. Known as NL2SQL), and then build the answer based on the query result of the SQL query statement. A table is a storage method for structured data. Tabular data refers to organizing and storing structured data in a table according to a table structure. [0003] However, in th...
