Abstract

The invention relates to the technical field of computers, in particular to a method and a device for providing information. The method comprises the steps of receiving a user login request sent by a terminal; returning a corresponding webpage content to the terminal according to the user login request, wherein the webpage content include article information related with user's past behaviors which are behaviors of articles provided by a website webpage belongs to before the user logs in this time. The obtaining process of the article information related with the user's past behaviors comprises the steps of obtaining a frequent item set according to an article matching set and user behavior data corresponding to the article matching set in iteration and hash modes; obtaining the article information related with the user's past behaviors according to the obtained frequent item set. By adopting the method, the frequent item set is obtained in iteration and hash modes, and the practicability of provided information is improved.

Description

technical field [0001] The invention relates to the field of computer technology, in particular to a method and device for providing information. Background technique [0002] With the rapid development of computer technology, the Internet has become an important way for users to obtain information about items. When a user operates an item, he usually operates multiple items at the same time, and there is a strong association between the multiple items operated at the same time, wherein the items operated at the same time are the item set of the item. According to the strong association between items operated by the user, information can be effectively reminded to the user. [0003] In the existing method for providing information, the provided information is obtained through a collaborative filtering algorithm. The collaborative filtering algorithms used are mainly: user-based collaborative filtering and item-based collaborative filtering. User-based collaborative filter...
