Learning apparatus in digital environment

A learning apparatus in a digital environment, characterized in that the system comprises a cloud server platform and a terminal device, wherein the cloud server platform further comprises a knowledge point structurized storage apparatus and a user information storage apparatus;

• the knowledge point structurized storage apparatus comprises a knowledge point library module, a tag library module, a relationship library module and a structurized knowledge library module, wherein:
• the knowledge point library module stores various knowledge points;
• the tag library module stores tags of the various knowledge points, with the tags and the knowledge points being in one-to-one correspondence;
• the relationship library module stores a relationship among the various knowledge points;
• and
• the structurized knowledge library module constructs a knowledge point structure based on the relationship among the various knowledge points and stores all the knowledge points with the structure;
• and
• the user information storage apparatus stores user information about various users, wherein each piece of user information at least comprises a user attribute, tag classification information about the knowledge points corresponding to the user, relationship information about the knowledge points corresponding to the user, structurized knowledge corresponding to the user and social attribute information about the user, wherein the tag classification information about the knowledge points corresponding to the user is a classification of tags based on the user's mastery degree for the knowledge points, the relationship information about the knowledge points corresponding to the user is a relationship among the knowledge points learnt by the user, the structurized knowledge corresponding to the user refers to a knowledge point structure constructed based on the relationship among various knowledge points learnt by the user, and the social attribute information about the user refers to the user's attitude to sharing the learnt knowledge points.
