Problems solved by technology
With the development of Internet technology, the amount of information on the Internet is growing explosively, the number of individual stock announcements is too large, and the traditional MySQL and PostgreSQL database systems are relational database systems, which have strong transaction processing and data analysis functions. However, due to the complexity of demand semantics, the response speed of traditional databases will be significantly reduced due to a large number of data statistical analysis operations

The invention discloses a query processing method, which comprises the following steps: receiving an input query script, defining a Mongo database data format, and converting an original database intoa Mongo database matched with the query script; Defining a natural language processing interface and a front-end display interface; An input natural language query statement is received, and query condition information in the natural language query statement is obtained through a natural language processing interface; Utilizing the query script to perform query processing in the Mongo database according to the query condition information to obtain a query result; and displaying the query result through a front-end display interface. According to the method, when the natural language query statement is received, query processing can be carried out in the Mongo database according to the query condition information in the natural language query statement, and the problem that the response speed is reduced due to the complexity of the required semantics is avoided. The invention further provides a query processing system and device and a computer readable storage medium which have the above beneficial effects.
Description
technical field [0001] The present application relates to the field of query processing, and in particular to a query processing method, system, device, and computer-readable storage medium. Background technique [0002] Stock announcements are the most authoritative and timely information display window for listed companies, and their content is likely to have an important impact on investors' judgment of the company's fundamentals. Stock announcements often include all kinds of accurate and objective data information, important time periods and time node information, and the progress, operation, and preconditions for implementation of many matters. [0003] For investors, it is particularly important to obtain the information in individual stock announcements quickly and accurately. In the prior art, users usually query the information on individual stock announcements in the database by inputting keywords and query conditions. Match in , and output all data information t...
