Abstract

The invention belongs to the technical field of data processing, and discloses an interactive unsupervised label classification system, method, medium, and terminal, which use pseudo-labels and pre-trained models to perform unsupervised classification on data sets, and perform auxiliary classification by adding and expanding vocabulary , and adding negative nodes or negative samples to exclude negative samples in the pre-training model. The invention satisfies the business requirement of dividing data sets according to different label systems in different business scenarios, and proposes a general data processing flow, which can solve unsupervised or weakly supervised label classification tasks. The present invention mainly uses pseudo-label learning technology, which can solve the problem of cold activation; reduce the demand for labeling data; adjust the label system structure in real time; allow manual intervention; visualize the relationship between label systems; Sample or parent node.

Description

technical field [0001] The invention belongs to the technical field of data processing, and in particular relates to an interactive unsupervised label classification system, method, medium and terminal. Background technique [0002] At present, with the popularization of the electronic and information age, various types of documents are pouring in, such as: news, papers, patents, periodicals, etc., each type of text has its own unique fields of application and structural characteristics, through a single label system , it is impossible to reasonably classify various types of documents at the same time, and it is necessary to use multiple label systems. Even for a single type of style, only a single label system cannot be fully expressed. Taking patents as an example, only a single IPC classification can be used. Express its technical field, but its ability to express its application field is insufficient. In order to meet various application scenarios, it is necessary to use...
