Abstract

The invention discloses a label propagation clustering method, terminal equipment, storage medium and device. The method includes: acquiring frequent words of each text; extracting text information of the text from a sample text set, and passing through Build a heterogeneous text network with a preset mapping relationship; generate a node influence threshold through the preset node influence relationship for the corresponding text nodes in the heterogeneous text network, and obtain a target label according to the node influence threshold; in the heterogeneous text network In the quality text network, the total similarity threshold between the texts is generated through the preset total similarity relationship, and the target text node is obtained according to the total similarity threshold; the target label is propagated between the target text nodes , and cluster the text corresponding to the same target label to obtain clustering result clusters. The technical scheme of the invention can solve the technical problems of label propagation randomness and clustering accuracy and low reliability.

Description

technical field [0001] The present invention relates to the technical field of tag propagation and clustering, in particular to a tag propagation clustering method, a terminal device, a storage medium and a device. Background technique [0002] At present, in agricultural production, information retrieval, financial and biological information processing, etc., it is necessary to process a large amount of data information before using it. Generally, labels are used for dissemination and processing before clustering; for example, in the study of crop pests When analyzing, it is necessary to mark the damage phenomenon of the damaged crops, and then judge whether it belongs to which type of pest. Using the label propagation algorithm, the phenomenon can be quickly clustered to obtain the results, and finally the pest can be remedied . However, this label propagation algorithm not only has randomness, but also has low accuracy and reliability after clustering the marked data. ...
