Method and device for searching music and building index, and method for judging search results

Abstract

Embodiments of the invention disclose methods and apparatuses for searching music and establishing an index, and a search result judgment method. The method for searching the music comprises: receiving a query string and performing word segmentation on the query string to obtain one or more query words; obtaining a candidate first song set according to the query words; obtaining an arrangement attribute of songs in the first song set, and performing segmentation on the query string according to the position offset of the query words in the arrangement attribute of the songs to obtain one or more segmented texts; matching the segmented texts with the arrangement attribute of the songs, and calculating a correlation weight of the query string and the songs based on a matching result; and sorting the songs in the first song set according to the correlation weight of the query string and the songs to obtain a second song set, setting the second song set as a search result of the query string, and returning the search result to a user. According to the method for searching the music, provided by the invention, the returned search result can better conform to the search intention of the user.

Description

technical field [0001] The present application relates to the field of search technology, in particular to a method and device for searching music and building an index, and a method for judging search results. Background technique [0002] With the development of computer technology and multimedia technology, music search is widely used because it can retrieve music information that meets the user's intention for a large number of users. [0003] In the technical field of music search, a song usually includes multiple arrangement attributes, such as song name, artist name, album name and so on. When users search for music, they generally construct query strings according to the arrangement attributes. Usually, a query string may match one permutation attribute of a song, or a combination of multiple permutation attributes. In addition, the user may use incomplete arrangement attribute information and combinations thereof to construct query strings due to incomplete unders...

AI Technical Summary

Problems solved by technology

[0006] In the process of implementing this application, the inventors found that there are at least the following problems in the prior art: Considering the impact of the positional relationship of keywords in the query string on the user's search intention, the existing music search method only applies to all keywords in the query string. The inverted index of the keywords is used to find the intersection. The accuracy of the search results returned by this method still needs to be improved
