Abstract

The embodiment of the invention relates to the technical field of text data processing, and discloses a topic mining method, system and device based on a short text and a storage medium. The method comprises the steps of firstly obtaining a to-be-processed short text; and extracting topic distribution information in the to-be-processed short text through a preset short text topic mining model. Visibly, according to the embodiment of the invention, the topic mining operation of the short text is processed by applying the topic mining model special for short text processing, so that the topic ofthe short text can be accurately mined, and the technical problem that the topic of the high-quality short text is difficult to accurately mine is solved.

Description

technical field [0001] The invention relates to the technical field of text data processing, in particular to a short text-based topic mining method, system, device and storage medium.
