Inquiry method and device based on hierarchical label, equipment and storage medium

Abstract

The invention discloses a query method and device based on hierarchical labels, equipment and a storage medium. The method comprises the steps of when a voice query instruction is received, analyzingthe content of the voice query instruction to obtain a keyword of the voice query instruction; determining a combination relationship of the keywords according to the acquired keywords, and constructing a retrieval formula according to the combination relationship of the keywords; and based on the retrieval formula, retrieving a tag set composed of a plurality of hierarchical tags in a database, and outputting a retrieved file as a query result. And through a retrieval formula constructed by the voice query instruction, in combination with a label set composed of a plurality of hierarchical labels in a database, the target file is retrieved and a query result is output. Due to the fact that detailed retrieval information is prevented from being input manually, the target file can be retrieved rapidly and accurately, and the beneficial effects of reducing time consumption and improving retrieval efficiency are achieved.

Description

Technical field [0001] The present invention relates to the field of information query, in particular a query method, device, equipment and storage medium based on hierarchical tags. Background technique [0002] With the development of technology and the Internet, people are producing more and more files, and the size of files has also become larger due to the improvement of file content. Therefore, in order to facilitate the storage of files, various databases and storage spaces have emerged. However, in the prior art, when people retrieve stored files, they need to input detailed information to accurately retrieve the target file. For example, when public security personnel retrieve voice files for evidence collection, they need to manually enter retrieval information, such as The target file can be retrieved only with the specific date, prisoner's name, geographic location, etc. This requires public security personnel to be familiar with the stored files; in addition, the re...
