Problems solved by technology

This content-based user interest discovery method is essentially based on statistical information. It does not make full use of the comprehensive structural information and rich semantic information such as different types of objects and different interaction semantics in the heterogeneous information network, and cannot be well developed. Reflect the user's real interest in the song

Abstract

The invention relates to a method for finding user interests in a music information network. Firstly, an information subnet related to a user and a network mode of the information subnet are obtained through N-step long random walking in the music information network; next, pruning is carried out on the information subnet, correlation among different types of nodes is calculated in the pruned information subnet through a HeteSim algorithm, and weights of different types of edges are obtained; then, a shortest path set and shortest path weights of all songs are obtained according to a unisource shortest path algorithm, and an element path set and an element path weight are worked out; finally, the songs are clustered into three types based on element paths through a PathSelClus algorithm, and the interests and hobbies of the user to the songs are analyzed according to a clustering result. According to the method, the significance character of the element paths in the heterogeneous information network is utilized, and the interests of the user to the songs can be found better.

Description

Technical field [0001] The invention relates to the field of information retrieval, in particular to a method for discovering user interests in a music information network. Background technique [0002] The music information network is actually a heterogeneous information network composed of an information subnet and a social subnet. The information subnet usually contains songs and song-related type nodes, such as singers, lyricists, genres, etc., which exist in the network. Relationships include the relationship between songs and singers, the relationship between songs and lyrics, the relationship between songs and genres, etc. The social subnet includes the relationship between users. Friend relationship, song-player relationship between users. [0003] At present, the user interest discovery method in the music information network mainly uses the singer, lyricist, genre and other information of the song as the attribute features of the song, and then maps the user-song ...
