Embodiment Construction

[0036] The specific implementation manners of the present invention will be further described in detail below in conjunction with the accompanying drawings and embodiments. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0037] figure 1 A schematic flow chart of a method for analyzing emotional stress of a song provided by an embodiment of the present invention is shown.

[0038] In step S1, the lyrics are segmented, for example, the lyrics are divided into vocabulary, preferably, the lyrics can be firstly divided into sentences, and then the sentences are divided into vocabulary. The lyrics of the song can be in LYRIC file format (*.LRC) containing time information and lyrics information. The sentence segmentation strategy is relatively simple, and the lyrics line of the LRC file is directly regarded as a sentence. When lexical segmentation, a two-way maximum matching strategy is adopt...

Abstract

The invention discloses a song emotion pressure analysis method comprising steps: S1, cutting the lyrics; S2, judging the structure of lyrics by analyzing the repetition, parataxis of the lyrics and the lyrics fragment sequence; S3, determining the average singing speed of the song according to the words of the lyrics and the singing time; S4, abstracting the emotion unit from the lyrics and judging the emotion pressure polar of the emotion unit; S5, calculating the lyrics emotion pressure index according to the structure of the lyrics, the average singing speed of the song and the emotion pressure polar of the emotion unit. Based on the method, the user can exactly position the required song, thereby improving the song searching hit rate and shortening the song searching time.

Description

technical field [0001] The invention relates to song analysis technology, in particular to a song emotional pressure analysis method and system based on lyrics. Background technique [0002] The demand for songs in the current society is increasing day by day, and listening to songs has shifted from personal computers to online audio-visual on the Internet. The gradual popularization of 3G communication networks will inevitably promote the expansion of song operations from the Internet to mobile phones. In response to the above needs, various intelligent song search and recommendation systems have gradually emerged. Song classification is a key technology for intelligent song search and recommendation. The goal is to give songs a specific category label to facilitate user search or system recommendation. Song categories include objective categories and connotative categories. For example, geographical category is an objective category set according to the location of song ...
