Problems solved by technology

However, with the continuous expansion of the resource base, the result of keyword search is only the accumulation of a large number of resources, lacking the integrity and systematization of the course content, the level is not clear enough, and the recall rate and precision rate are no longer sufficient. satisfy people's demands
[0004] There are already many online course resources on the market today. Although there are huge resource banks as support and rich content, the structure is complicated and unclear. Easy to cause stray phenomenon

Embodiment Construction

[0030] The present invention will be further described below in conjunction with the accompanying drawings.

[0031] Such as figure 1 Shown is the hierarchical structure diagram of the present invention. The bottom layer is the resource entity layer, including teaching resources in various formats, which are stored on the server. The middle layer is the semantic layer, which is the most important part of the whole framework. In fact, the database is used to store resource entity descriptions and knowledge point information to form resource description tables and knowledge point tables. Among them, the knowledge point table is compiled into an Excel table by experts in various disciplines, and then imported into the database after compression and analysis, recording information such as the relationship between knowledge nodes and the mapping relationship between resources and knowledge maps. The topmost layer is the display layer, which presents the resource list retrieved fr...

Abstract

The invention discloses a knowledge map based resource retrieval method applied to help learners to quickly position study resources as needed and guide the learners to learn. The method includes the following steps: 1), organizing knowledge points; 2), creating a knowledge map; 3) mapping resource entities to the knowledge map; 4), retrieving and displaying resources. The knowledge map based resource retrieval method is quick to retrieve and accurate in positioning.

Description

technical field [0001] The invention is a resource retrieval method based on a knowledge map, which is used to help learners quickly locate required learning resources and guide learners to learn. Background technique [0002] The development of information technology and the popularization of online distance education have led to a rapid increase in various educational resources. When students search online, they often get lost in the ocean of resources and cannot find the resources they want. The increasingly large network resource library provides more choices of learning resources for network learners, but at the same time increases the difficulty of searching resources, making it difficult to find target resources. [0003] The traditional subject resource retrieval is mainly based on the keyword method. Its three models, such as Boolean model, vector model and probability model, are simple, fast and easy to implement. They have met people's needs for a long time and ar...
