Label system construction method, device, electronic device and storage medium

Abstract

The present disclosure relates to a method, device, electronic device and storage medium for constructing a tag system. The method includes: obtaining a search word sequence, where the search word sequence includes multiple historical search words; obtaining search word vectors corresponding to the historical search words; Perform multi-level clustering on word vectors to obtain multi-level clustering results, and the multi-level clustering includes at least a first-level clustering and a second-level clustering; wherein, the first-level clustering includes: clustering multiple search word vectors. The second-level clustering includes: clustering multiple first-level categories to obtain second-level categories, and the number of second-level categories is less than the number of first-level categories; based on historical search terms and multi-level clustering The correspondence between the results generates the initial labeling system. The initial label system generated by this method has more reasonable structure division, finer granularity of label division, and bottom-up construction method, which can fully describe users' demands in search, and is more accurate and reliable.

Description

technical field [0001] The present disclosure relates to data processing technologies, and in particular, to a method, device, electronic device and storage medium for constructing a label system. Background technique [0002] The search tag system is a detailed description and division of the user's search intent, and it is used in a wide range of search scenarios. In the related art, the tag system of video search is mainly divided according to the video content, such as music, dance, entertainment, sports and so on. At present, this division method mainly relies on manual work, that is, the system is characterized and described as a whole through human prior knowledge. [0003] Since the construction of the current labeling system mainly depends on the subjective cognition of people, different people have different cognitions, which makes the built labeling system have a lot of problems such as overlap, repetition, and membership errors, resulting in an unreasonable syst...
