Problems solved by technology

Since the output space of multi-label classification increases exponentially with the number of label items, when the number of label items is large, this classification method of directly predicting all-level labels takes a long time and is relatively inefficient.

Abstract

The invention relates to a method for classifying text data, which comprises the following steps: predicting a first label item string of the text data, which is used for representing a first-level category of the text data, and the first label item string comprises one or more levels of label items with a progressive relationship; according to the first-level category of the text data, predicting a second label item string, used for representing a second-level category of the text data, of the text data, where the second-level category belongs to a sub-category of the first-level category, and the second label item string comprises one or more levels of label items with progressive relations; and performing splicing according to the first label item string and the second label item string to obtain a classification result of the text data. The invention further relates to a device for classifying the text data, a computer readable storage medium and electronic equipment.

Description

technical field [0001] The present application relates to data processing, in particular to a method and a device for classifying text data whose category is indicated by a label implying a multi-level progressive relationship. Background technique [0002] In data classification, labels are often used to indicate the category to which the data corresponds. At present, there are two main label systems, one is a single and independent fragmented label system, such as the label system of NetEase Cloud Music, its label set includes "Chinese", "Japanese", "Cantonese", "popular", " Rock", "folk" and other labels. In the fragmented label system, each label contains only one label item, and they are independent of each other and have no joint relationship. The other is a label system that implies a multi-level progressive relationship, in which each label contains multiple label items separated by separators and arranged in a progressive relationship, so that a string is composed...
