Embodiment Construction

[0074] In order to understand the present invention more clearly, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0075] refer to figure 1 As shown, the figure clearly shows the knowledge elements contained in the computer network course and the relationship between them. Among them, services, protocols, etc. are concepts, and the definitions of protocols and subnet masks are knowledge elements. The relationship between concepts in the figure is represented by thin arrows, and the text above the thin arrows indicates the relationship type. For example, the concept of "service" and the concepts of "connection-oriented service" and "connectionless service" belong to the relationship between classes and subclasses, while the relationship between the concepts of "protocol" and "IP" is the relationship between classes and instances relation. The relationship represented by the knowledge element is represented by a t...

Abstract

The invention discloses a method for obtaining user specific metaknowledge interest. The method is specific to a learner in a network learning system, aims at exactly identifying and obtaining learning interest of the network learner, predicts the future interest change of the learner, and improves learning efficiency and performance of the network learner. In the aspect of user model, a user interest model facing the network learner group is adopted. In the interest omission algorithm of dynamic interest perception, an interest omission algorithm featuring automatically discovering and omitting the threshold is adopted. In the interest prediction algorithm, a prediction method featuring user collaborative prediction is adopted. The invention analyzes blogs of the learner to exactly identify the interest change of the user towards metaknowledge, conception and learning resource, reflects interest degree in a quantitative way, predicts the interest change of the learner, improves defects of the existing technologies, and has good application prospect in the network learning system and network individual service.

Description

[0001] Field [0002] The invention belongs to the technical field of computer design and application, and relates to a method for obtaining the degree of interest in specific knowledge elements of users.
