Embodiment 1
[0052] This embodiment provides a marketing text recognition method. First, an independent text graph is constructed for each document, and a label graph is constructed by using the label information of the training set; then a topic model is trained by using the label information corresponding to the text graph nodes and the text graph, Generate the topic word probability distribution; then build a perceptron to map the topic word probability distribution to the label vector space, build a graph convolution network, learn the label correlation and semantic information under the guidance of the label graph, and update the label vector to obtain the label embedding representation; Finally, after jointly learning words and labels to obtain the final text representation, the final classification result is output through the sigmoid layer. like figure 1 shown, including the following steps:
[0053] Step 1: Obtain the training set and the text to be recognized, and perform data p...
Embodiment 2
[0121] This embodiment provides a marketing text recognition system, which specifically includes the following modules:
[0122] A preprocessing module, which is configured to: obtain the text to be recognized, and perform preprocessing;
[0123] The graph building module is configured to: construct a text graph of the to-be-recognized text based on the pre-processed to-be-recognized text;
[0124] a joint learning module, which is configured to: generate a text-level word representation based on a text graph of the text to be recognized, and combine the embedded representations of all tags to generate a text representation;
[0125]A classification module, which is configured to: based on the text representation, use a classifier to obtain a result of whether the text to be recognized belongs to the marketing text;
[0126] Among them, the method of obtaining the embedded representation of the label is: based on the text map of the training set and its labels, generate the p...
Embodiment 3
[0129] This embodiment provides a computer-readable storage medium on which a computer program is stored, and when the program is executed by a processor, implements the steps in the method for recognizing marketing text as described in the first embodiment above.
