摘要:针对内容推荐系统中的瓶颈问题——特征表示问题,将特征属性进行了排序,并利用高斯函数获得产品的属性取值.进而借助Topsis中理想解与负理想解的思想定义了产品在各个属性上的相似性,并通过Topsis中属性间的可补偿性获得了产品间的相似度.
Focused on the trouble of the features representation of merchandise in Contentbased Recommendation system. In this paper, the features were ranked with their important. Meanwhile, with Gaussian function, the indexes of features were obtained. With the ideM solution and negative ideal solution of Topsis, the similarity of each feature of product was de- fined. Finally, the similarity between the products was get by the attribute of compensatory in Topsis method.
