Abstract

The embodiment of the invention discloses a music genre classification method and device and a storage medium. The scheme comprises: collecting positive and negative samples of preset genre music; extracting first lyric text data of music in the positive and negative samples; preprocessing the first lyric text data; extracting audio data of music in the positive and negative samples; preprocessingthe audio data; compressing audio data, and extracting a first audio feature in the compressed audio data; and extracting semantic codes of the first lyric text data according to the trained preset language model, combining the semantic codes with the first audio features, inputting the combined data into a music classification model generated based on the language model for training, and determining the music genre of the to-be-classified music according to the trained music classification model. According to the scheme provided by the embodiment of the invention, the genre of the to-be-classified music is determined through the trained classification model, and the accuracy of music genre classification is improved.

Description

Technical field [0001] The present invention relates to the technical field of data processing, in particular to a classification method, device and storage medium of music genres. Background technique [0002] At present, with the development of the Internet, people have more and more access to the music content provided by the Internet, and the requirements for music services are also getting higher and higher. Efficient music information retrieval can help people find music resources that meet individual needs from massive data. A common search method, you can search for songs by genre and genre tags. However, due to the large number of songs in the music library and the high cost of manually assigning tags, there are still a large number of songs without genre or genre tags. Therefore, major music platforms usually adopt the method of constructing genre / genre classifiers to automatically assign songs. Assign the corresponding label. [0003] Currently, genre classification o...
