Embodiment Construction

[0024] In order to make the purpose, technical solution and advantages of the present application clearer, the present application will be further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the present application, not to limit the present application.

[0025] use as figure 1 The graphical programming tool shown is often used to provide graphical programming learning for teenagers. The process of establishing the program uses interesting processes such as graffiti, recording, and finding pictures. Students' works can be directly published on the official website of the graphical programming platform, and the published works can be viewed by other users on the network. This application is applied to this graphical programming tool to recommend works for users.

[0026] In one embodiment, such as figure 1 As shown, a graphical programmi...

Abstract

The invention discloses a graphical programming platform resource recommendation method and device. The method comprises the steps of obtaining a user cluster where a target user is located for the target user, enabling the user cluster where the target user is located to correspond to a user score matrix, and obtaining a dimension-reduced user score matrix; calculating the score similarity between the target user and other users by adopting the dimensionality-reduced user score matrix to obtain a neighbor set of the target user; and adopting the neighbor set of the target user to predict and score the works which are not scored by the target user, and selecting a preset number of works with high scores according to a predicted score value and recommending the works to the target user. According to the technical scheme, resource pushing is facilitated, a foundation can be laid for subsequent programming courses, and the method is of great significance in improving the interest of the user and improving the programming ability.

Description

technical field [0001] This application belongs to the field of educational resource recommendation, and in particular relates to a resource recommendation method and device for a graphical programming platform. Background technique [0002] Scratch is a graphical programming tool developed by MIT's "Lifelong Kindergarten Team", which is mainly open to teenagers. The process of establishing the program uses interesting processes such as graffiti, recording, and finding pictures. Students' works can be published directly to the official website through the software. The published works can be seen by countless people through the Internet. Therefore, in this learning environment, how to intelligently recommend works of interest to students and improve students' learning interest has become very necessary. [0003] For student users, through the existing student user behavior habits, find student groups with the same hobbies, and then analyze the user behavior in the group t...
