The Semantic Retrieval System for Learning Resources Based on Subject Knowledge Ontology

摘要

There are many kinds of learning resources in the online education platform, but there are still many problems, such as learning resources are difficult to retrieve, search results are redundant, and can only be retrieved by keywords, but lack of semantic support. This paper integrated semantic web into the retrieval of learning resources, and designed the subject knowledge ontology as the knowledge description of learning resources semantic retrieval system, and implemented the semantic retrieval of learning resources through ontology concept similarity analysis, ontology reasoning and ontology in computing and other sectors, to reduce the redundancy of information retrieval results and realize the display of high related resources.
