Course and teaching outline combined ontology learning guide method and system

Abstract

The invention relates to a course and teaching outline combined ontology learning guide method and system. The method comprises the steps of obtaining a user demand of a set application scene; determining fields and ranges of course and teaching outline applications according to the user requirements; determining an entity according to the field and range of the course and teaching outline application and a conditional random field model based on fusion features; constructing an ontology of a course and a teaching outline according to the entity; and learning is guided according to the courseand the body of the teaching outline. According to the invention, the accuracy of learning guide results is improved.

Description

technical field [0001] The invention relates to the field of semantic search, in particular to a teaching guidance method and system combining courses and ontology of teaching syllabus. Background technique [0002] With the development of Internet technology, new network technologies have had a significant impact in various fields of society, and many studies on integrating network technology into the field of education have been derived. The application of semantic web and ontology technology in the field of education has been used to invent Semantic models of various learning entities. Ontology conceptualized domains of knowledge can be understood not only by humans but also by computers using formal languages. Ontologies describe the concepts in a domain and the relationships between them, and provide a vocabulary for the terms used. Semantic annotation of concepts and terms can be processed and understood by humans and machines. Curriculum and syllabus provide import...

AI Technical Summary

Problems solved by technology

The characteristics of resources in different fields have different ontology construction methods, and the traditional ontology construction methods cannot meet the needs of our research fields.

[0003] Most of the teaching syllabi we are currently in contact with are displayed in the form of documents. When searching for relevant information on the Internet, we cannot feed back the results we want. Usually, what is returned is a whole document or a large paragraph of text. The difference between the course and the syllabus The connections are not well applied in practical teaching

The value of the syllabus cannot be well explored by both students and teachers, and there is currently no complete system for retrieving knowledge related to courses and syllabus

At present, most of the keyword-based search systems cannot understand the user's semantics very well, and the returned results are not accurate enough.
