Abstract

The invention discloses a text feature determination method and device. The method includes the steps that after a text of a to-be-recognized industry is determined, marking operation is executed on the text of the to-be-recognized industry, and the accuracy and efficiency of executing the hash value determination operation of the text can be improved; and the mapping operation is automatically executed on the determined hash value of the text without depending on a fixed word list. Therefore, the word data volume of the text can be reduced under the condition that the words of the required text are kept, so that the feature vector of the accurate text can be quickly determined, and the accuracy and efficiency of identifying the industry category matched with the text can be improved.

Description

technical field [0001] The present invention relates to the technical field of text processing, in particular to a method and device for determining text features. Background technique [0002] As an important channel for merchants and companies in different industries to promote and market products, Internet advertisements often include the brand, name, and related introduction, ingredients, and slogans of the corresponding promoted products. Effectively classifying them by industry is helpful for advertising in different industries. Explore brands and categories embedded in form and advertising. Among them, in order to accurately identify the industry of the advertisement text, it is very necessary to first determine the digital features of the advertisement text. The traditional method is to use the one-hot one-hot encoding method to process the traditional long string of words to obtain the digital features of the text. However, it has been found in practice that the o...
