Problems solved by technology
That is, the two users cannot establish a similarity relationship
From this, it can be seen that the similar users that can be covered by traditional user-based collaborative filtering algorithms are very limited, and the calculation of user similarity is not accurate enough. Therefore, it is impossible to effectively recommend products to users.

The present invention provides an information push method and apparatus based on a similarity degree between users. The method comprises: obtaining historical operation information of a plurality of users, and performing clustering processing on service objects comprised in the historical operation information to obtain a service object set; according to information of user operation on the service object in the service object set, obtaining attention degrees of different users to different service object sets; calculating a similarity degree between users according to the attention degrees; receiving a login request of a current user, and obtaining attribute information of the current user ; obtaining a similar user corresponding to the current user according to the attribute information and the similarity degree between users; and recommending a corresponding service object to the current user according to the historical operation information of the similar user. The method and apparatus provided by the present invention can cover more similar users and provide more service object recommendation information for the user so that it is easier for the user to view a related service object according to service object recommendation information.
Description
technical field [0001] The invention relates to the technical field of the Internet, in particular to a method and device for pushing information based on the similarity between users. Background technique [0002] In Internet technologies, websites often need to recommend various product information to users. For example, an e-commerce website recommends products that users may be interested in on a web page. Through this recommendation method, the path for users to find the products they need is shortened and the user experience is improved. [0003] Currently, user-based collaborative filtering recommendation algorithms are mostly used in e-commerce recommendation systems to recommend product information to users. The algorithm evaluates the similarity between users by analyzing the ratings of different users on the same product, and makes recommendations based on the similarity between users. When the number of users is far greater than the number of products, the reco...
