Problems solved by technology

[0003] In the prior art, when calculating the entropy value of each descriptive word, a simple calculation is only performed based on the appearance of the descriptive word in the title of the business object, and the accuracy rate obtained is relatively low, that is, some tags calculated in this way It may not really represent the main characteristics of the business object, and when using this tag for clustering or relevance recommendation of the business object, the results obtained will not be accurate enough

Embodiment Construction

[0031] The following will clearly and completely describe the technical solutions in the embodiments of the application with reference to the drawings in the embodiments of the application. Apparently, the described embodiments are only some of the embodiments of the application, not all of them. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in this application belong to the protection scope of this application.

[0032] First of all, it needs to be explained that in practical applications, people are usually used to looking for the change rule of a thing over a period of time, and can predict the next change under certain circumstances, such as predicting the weather. Therefore, in this embodiment of the application, in order to obtain the tags of the business objects more accurately from the text description information of the business objects, some training corpus can be obtained first, and a training model can be established...

Abstract

The invention discloses a method and a device for acquiring business object labels and building a training model. The method includes: acquiring the word description information of a target business object, and performing word segmentation on the word description information to obtain a plurality of description words; extracting the features of each description word; inputting the features of the description words and the text information of the description words in the target word description information into a preset training model, and determining whether the description words can be used as the labels of the corresponding business object or not according to the output results of the training model, wherein the training model is used for predicting the probability that the description words in the target word description information can be used as the labels of the corresponding business object, and the probability is related to the features of the current description words and the text information of the current description words in the target word description information. By the method, predicting results are high in accuracy.

Description

technical field [0001] The present application relates to the technical field of text data processing, in particular to methods and devices for acquiring business object tags and establishing training models. Background technique [0002] With the development of Internet technology, users can conduct various businesses on the Internet. In order to carry out various businesses smoothly, various business objects need to be displayed on the Internet, and such business objects can often be displayed through pictures, text descriptions, or videos. For example, commodity objects displayed on an e-commerce platform, etc. In practical applications, in order to facilitate correlation clustering of business objects, or to recommend related business objects to users when users browse a certain business object, it is often necessary to add tags (Tag) to each business object. Further describe the main characteristics of the business object. In actual implementation, this kind of label...
