Man-machine interaction method, device and equipment based on table data

Abstract

The invention provides a human-computer interaction method, device and equipment based on table data. According to the method, the retrieval library is constructed offline, and the SQL statements of table data support query and the problem representation vectors corresponding to the SQL statements are stored in the retrieval library. During online question answering / dialogue, an input question is encoded to generate a semantic representation vector of the input question, and similarity matching is performed on the semantic representation vector of the input question and a question representation vector in a retrieval library, so that an SQL statement accurately matched with the input question can be found, and Text-to-SQL language conversion is realized; model training does not need to be carried out based on a data set in a specific application field, generalization is higher, and efficiency is higher; furthermore, the SQL statement corresponding to the input question is operated, the table data can be inquired to obtain the answer information of the input question, the response time during online question answering / dialogue can be shortened, and the response timeliness of the human-computer interaction system based on the table data is improved.

Description

technical field [0001] The present application relates to the field of artificial intelligence, and in particular, to a method, device and device for human-computer interaction based on table data. Background technique [0002] The human-computer interaction system (Table QA) based on tabular data is to convert the natural language questions input by the user into SQL statements, and find the results corresponding to the SQL statements in the data table used to store the tabular data in the database and feed it back to the user. . Since tables are a common data storage structure in daily work and life, the human-computer interaction system based on table data has a wide range of application scenarios, such as data query, statistics and screening, etc., which can be applied to government affairs, finance, energy, etc. in the field of application. [0003] At present, the human-computer interaction system based on tabular data uses the language conversion model to convert th...
