Abstract

The invention discloses a deep hash retrieval method and device and a medium. The method comprises the steps that a hash retrieval model pre-generated through multiple sets of training samples and a preset algorithm is determined; generating and storing a hash code corresponding to each article through a hash retrieval model; determining a to-be-retrieved article input by a user, and outputting ahash code of the to-be-retrieved article through the hash retrieval model; and determining a retrieval result according to the hash code of the article to be retrieved and the stored hash code corresponding to each article. According to the method, the hash retrieval model is trained and generated through the preset algorithm, so that the hash retrieval model can effectively consider the content contained in the article when aiming at the article to be retrieved input by the user, the quality of the generated hash code is improved, the final retrieval accuracy is also improved, and the user experience is improved. Complementary information between different modes can be fully mined, and compared with a single text mode detection method, the method has higher robustness.

Description

technical field [0001] The present application relates to the field of retrieval, in particular to a deep hash retrieval method, device and medium. Background technique [0002] In recent years, with the rapid development of the Internet, multimedia data (such as pictures, text, video, audio, etc.) has shown explosive growth. How to find the required information from the vast data stream has become a hot topic in current research. [0003] Usually, when people need to consult relevant information, they will search related articles in the same field according to the existing articles. However, when searching, if you only search based on the title or abstract of the article, the results are often not comprehensive enough, and it takes too much time to search after reading the entire article. The general solution is to search through the user input keywords, and then return the articles containing keywords. However, when the keywords given by the user are not accurate or suff...
