Abstract

The invention provides an information recommendation method, an electronic device and a storage medium. The information recommendation method comprises the following steps: preprocessing user scoringoriginal data of all projects, and randomly selecting a preset number of users from all the users as an original clustering center by utilizing a clustering algorithm according to the preprocessed data; then, according to the evaluation score of each project by the user, respectively calculating the distance from each user to each clustering center by adopting a formula of combining a normalized time function and a Pearson correlation coefficient, and classifying each user into a set corresponding to the nearest clustering center; and calculating the predicted score of the target user for eachproject according to the user data contained in each set, sequentially arranging all the projects according to the size order of the predicted scores to obtain a recommended project set, and recommending the projects in the project set to the target user according to the sorting order. By utilizing the information recommendation method, the information interested by the user can be predicted moreaccurately by combining the time attribute.

Description

technical field [0001] The invention relates to the field of intelligent decision-making, in particular to an information recommendation method, device and storage medium. Background technique [0002] The user-based collaborative algorithm finds a set of user data similar to the target user, uses this set of user data to predict the target user, and obtains the score value of the target user, thereby recommending users based on the score value. This does not take into account that the user's interests change over time and is inaccurate. Contents of the invention [0003] The present invention provides an information recommendation method, device and storage medium, the main purpose of which is to predict the information of interest to the user in combination with the time attribute and recommend it to the user, so as to improve the accuracy of information recommended to the user. [0004] In order to achieve the above purpose, the present invention provides an informatio...
