Abstract

The invention provides a data information classification method and device. The method comprises steps of obtaining the to-be-classified text information; sequentially performing vectorization processing, fusion processing and global average pooling processing on the text information to obtain the aggregated information corresponding to each feature vector; performing screening processing on the aggregation information by using two fully connected networks to obtain a screening parameter corresponding to each feature vector; judging whether the feature vectors are noise features or not according to the screening parameters, if yes, shielding the feature vectors, and updating the remaining feature vectors to obtain updated feature vectors; updating representation features of multiple aspects according to the updated feature vectors; dimension reduction processing being performed on the updated representation features of the multiple aspects so that a target feature can be obtained; andobtaining the classification information of the text information according to the target features. According to the method, the classification purpose can be achieved more comprehensively and accurately, and the method is simple, efficient and low in cost.

Description

technical field [0001] The invention relates to the technical field of information processing, in particular to a data information classification method, a data information classification device, a storage medium and electronic equipment. Background technique [0002] With the rapid development of the information age, the information resources on the Internet are becoming more and more abundant, the scale of information data is becoming larger and larger, and the forms of expression are becoming more and more diverse. However, for massive information and data resources, most of them can only be understood by humans, and it is still very difficult for machines to understand this information, especially the huge amount of text data, and natural language understanding has always been very popular. research field. [0003] In the process of natural language processing, text classification is particularly important as the basis for applications such as content classification, se...
