| Abstract: | Traditional researches on user preferences mining mainly explore the user's overall preferences on the pro ject, but ignore that the fundamental motivation of user preferences comes from their attitudes on some attributes of the pro ject. In addition, traditional researches seldom consider the typical preferences combination of group users, which may have influence on the personalized service for group users. To solve this problem, a method with noise reduction for group user preferences mining is proposed, which focuses on mining the multi-attribute preference tendency of group users. Firstly, both the availability of data and the noise interference on preferences mining are considered in the algorithm design. In the process of generating group user preferences, a new path is used to generate preference keywords so as to reduce the noise interference. Secondly, the Gibbs sampling algorithm is used to estimate the parameters of the model. Finally, using the user comment data of several online shopping websites as experimental objects, the method is used to mine the multi-attribute preferences of different groups. The proposed method is compared with other methods from three aspects of predictive ability, preference mining ability and preference topic similarity. Experimental results show that the method is significantly better than other existing methods. |
