Embodiment 1

[0026] Embodiment 1: as Figure 1-4 As shown, the cross-domain sentiment classification method based on multi-source domain integration transfer,

[0027] The concrete steps of described emotion classification method are as follows:

[0028] Step1. Using the Feature-extending NeuralStructural Correspondence Learning (FNSCL) model to obtain the source domain D s Migrate to the features of the target domain Dt, and then train different logistics classifiers, D s1 to D t Training to get logistics classifier 1, D s2 to D t Training to get logistics classifier 2, D s3 to D t Train to get logistics classifier 3;

[0029] As a preferred solution of the present invention, the FNSCL model uses the extended pivot feature to perform feature migration, and not only considers the mutual information MI value between the feature and the label in the training set when screening the pivot feature, but also considers the word frequency of the feature, And the TF-IDF feature selection al...

Abstract

The invention relates to a cross-domain emotion classification method based on multi-source domain integration migration, and belongs to the field of computer and information technology. The present invention comprises the steps: first, the neural structure corresponding learning FNSCL model of feature expansion is used to obtain the source domain D s Migrate to target domain D t features, and train different logistics classifiers; then according to the principle of ensemble consistency, calculate the weight of the logistics classifier; finally use the simulated annealing algorithm to optimize the weight of each classifier. The present invention can improve the emotion classification effect of cross-domain target domain, and the product review (electronic product review, book review, kitchen utensils review, DVD review) emotion classification experiment result of Amazon's four different fields shows that the multi-source domain-based A cross-domain sentiment classification approach that integrates transfer is effective.

Description

technical field [0001] The invention relates to a cross-domain emotion classification method based on multi-source domain integration migration, and belongs to the field of computer and information technology. Background technique [0002] At present, e-commerce has had a huge impact on our lives. The comment texts of historical consumers on e-commerce products are subtly affecting the purchase behavior of other consumers. Therefore, research on sentiment classification of product reviews on e-commerce platforms has gradually become a new research hotspot. However, the sentiment classification of product reviews is very domain-specific, and the performance of a sentiment classifier trained on labeled data in a certain field will drop more when applied to other fields. In response to this problem, the existing technologies are: Aue et al. proposed to train a classifier by mixing a small amount of labeled data and unlabeled data, the effect is good, and the trained model can...
