Embodiment Construction

[0024] The technical solutions in the embodiments of the present application will be described below with reference to the drawings in the embodiments of the present application.

[0025] It should be noted that like numerals and letters denote similar items in the following figures, therefore, once an item is defined in one figure, it does not require further definition and explanation in subsequent figures. Meanwhile, in the description of the present application, relative terms such as "first", "second", etc. are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply that these entities or operations, any such actual relationship or order exists. Furthermore, the term "comprises", "comprises" or any other variation thereof is intended to cover a non-exclusive inclusion such that a process, method, article or apparatus comprising a set of elements includes not only those elements, but also includes elements ...

Abstract

The invention relates to a model training method and device, a data processing method and device and electronic equipment, and belongs to the technical field of computers. The training method comprises the steps of obtaining a data sample set and divided the set into a training set and a test set according to a preset proportion, wherein the data sample set comprises a plurality of positive comment texts and a plurality of negative comment texts related to a specified target in a webpage; iteratively training a BERT model by using the training set and the test set to obtain a trained sentiment classification model, after an input layer of the BERT model passes through an embedded layer, respectively performing average pooling and maximum pooling along the length direction of a sentence sequence, and cascading the input layer and the maximum pooling. By improving the BERT model and considering the average response and the maximum response of each sentence, the trained word vector not only contains semantic information, but also considers the sentiment polarity expression of the whole sentence, so that the sentiment classification prediction accuracy is improved.

Description

technical field [0001] The application belongs to the field of computer technology, and specifically relates to a model training method, a data processing method, a device and electronic equipment. Background technique [0002] With the development of the Internet and the popularization of e-commerce, online shopping has become a popular shopping method, and shopping reviews on e-commerce websites have gradually increased. Feelings are of great reference value for consumers to choose products that meet their wishes. At the same time, they are also an important basis for businesses to improve their marketing strategies. With the massive accumulation of review information on e-commerce platforms, consumers are paying more and more attention to the subject information of products they are interested in, such as product quality, packaging, or delivery speed. Therefore, it is a hot topic to obtain the emotional information of product topics from e-commerce reviews. [0003] At ...
