Embodiment Construction

[0021] The invention provides a music retrieval method based on a semantic data set. The function of this method is that it can map audio content to a label-based semantic feature space by using a semantic annotation model, trying to overcome the difficulty of extracting acoustic features. Find the connection between raw signal and semantics. At the same time, the crawled music in the music database is also automatically marked using the trained model, so that the similarity between the retrieval example and the music database is compared in the semantic space, and semantically related music is obtained. A well-designed user interface , to fully express the semantic information to the user, and at the same time facilitate the user to make corresponding modifications to the semantic expression, and facilitate the user to express personal subjective feelings about a certain music. Saving user annotation information on songs is conducive to expanding Chinese music datasets, there...

Abstract

The invention discloses an establishment method of a music retrieval data set based on semantics, and belongs to the fields of cloud computing and big data. The method is used to solve the problem ofestablishing the music retrieval data set based on the semantics. Technical key points are crawling of Chinese song data, selection of labels and generation of a semantic vector set. An effect is thatuser retrieval intention can be more naturally and accurately acquired by the data set.

Description

technical field [0001] The invention relates to a method for establishing a retrieval data set, in particular to a method for establishing a semantic-based music retrieval data set. Background technique [0002] The semantics experienced in music, such as user subjective feelings such as mood and style, are one of the important factors that encourage people to listen to and pursue music. As a high-level semantic feature of music, music semantic recognition and semantic-based retrieval have always been the difficulties and hotspots of researchers in the field of Music Information Retrieval (MIR). The "gap" between the underlying physical features of music and the high-level semantic features has plagued and restricted the development of content-based music retrieval research. With the development of technology and the deepening of research, researchers have established the connection between musical features and semantics in various ways, gradually narrowing the gap. Many r...
